• Retrieve XDB$ index not the text ENUM_T values

  All,

  I have a type xdb xml element $ enum_t where I can't find a way to get the text associated with the index value. The only way I seem to be able to get the index value is through the point object relationship (.value) notation. It gives me the index value of the list of restriction. I saw another post referring to the same question, but never responded. I need this xml element limited by this list. Any help or ideas appreciated. I'm using Oracle 11 g.

  Thank you

  Tom

  Hi Tom,

  It is not the right approach for what you are trying to reach.

  XDB$ ENUM_T is internal stuff that is not intended to be handled directly.

  Always use the XQuery/XPath functions to access the node values.

  I need this xml element limited by this list.

  What you mean?

  Object-relational storage via an XML schema that you use? If so, what is the problem?

  Could you put a small suitcase to test?

• Reg: Difference between XQuery and XPath:

  Hi Experts,

  I tried google on this subject and read a few articles but found no adequate explanation or may not be able to understand.

  Of http://stackoverflow.com/questions/924551/difference-between-xpath-xquery-and-xpointer

  In general, XPath is a language used to locate accurate XML nodes in a DOM succinctly. XQuery is a superset of XPath which also provides FLWOR sytnax, which is similar to SQL. Finally, XPointer includes XPath, but also provides a simple model to address based on the post.

  It is also a good read - what is XQuery?

  Any other pointers? According to my understanding, both are used for the XMLs, like the SQL query for relational data. But if the two are similar, what is the reasoning behind the two different technologies?

  
  

  Please share your ideas in this regard.

  Kind regards

  Basic functions?

  http://www.w3.org/TR/XPath/#corelib

  Typing?

  http://www.w3.org/TR/xpath20/#ID-types

  "Transforming data" - you mean CFDS on XML data, right?

  More like SQL, but there is no strict equivalence.
  Given that XML is self-descriptive language, transforming one XML document into another also means the metadata change.
  This is where the concept of XML schema.

  What language do technical FLWOR come - XQuery or XPath?

  XQuery.

  For example:
  for $i in/root/point [1] / value
  where $i/@uom = 'kg '.
  Return to {data ($i)}

  applied to this XML document:
  
   
      123
   
   
  

  will return this sequence:

  123

  Here, / root/point [1] / value is an XPath expression (which is also an XQuery expression) but the construction of FLWOR is strictly XQuery.

• XQuery insert node and assign the value based on an XPATH expression

  Hello

  I am trying to write a function that receives an XML as input parameters and return updated XML output

  -nodes are removed from the input XML code

  -a node must be inserted and the node value must be 1 or 0, based on an XPATH expression

  I discovered how to remove nodes, I discovered how to insert a new node, but I can not set the value of the conditionally inserted node an XPATH expression.

  Here's my current procedure and below a sample of one XML of entry. I use Oracle 12 c.

  CREATE OR REPLACE FUNCTION STRIP_XML
  (
    IN_XML IN SYS.XMLTYPE
  ) RETURN SYS.XMLTYPE AS
  p_result XMLType;
  BEGIN
    select
        xmlquery(
           'declare default element namespace "http://mad.evs.com/search"; (: :)
            copy $d := .
            modify (
    delete node $d//MainCategory/@logId,
             delete node $d/MainCategory/@id,
  -- a lot more of those delete node
   -- insert a node, but the value 1 is conditional
             insert node <DMZ>1</DMZ> after $d/MainCategory/SDataSection/EventDate)
            return $d'
          passing in_xml
          returning content
          ) into p_result
          from dual;
  
  
    RETURN p_result;
  END STRIP_XML;
  

  The condition for the value of is

  
  

  HASPATH (//DigitalAssets/DigitalAsset [@ available = "true" and @videoFormatId = "11"] / VideoLocations/Videorental [@typeId = "8"]) then 1 else 0

  
  

  It is complex because DigitalAssets/DigitalAsset is a collection. Here is an example of an XML to entry

  
  

  
  

  <MainCategory xmlns="http://mad.evs.com/search" id="9" logId="3349" logType="3">
    <Name>Sport</Name>
    <Serie id="163" externalId="557">
    <TitleAKA>UCL 2006/07</TitleAKA>
    <DigitalAssets available="true" som="20:28:49:05" dur="00:02:46:04" videoDurationMinutes="3">
       <DigitalAsset available="true" som="20:28:49:05" dur="00:02:46:04" videoDurationMinutes="3" videoFormatId="3">
          <VideoLocations>
              <VideoLocation id="3" path="003349MA.mxf" typeId="1" locationId="1" priority="0"/>
              <VideoLocation id="3" path="003349MA.mxf" typeId="2" locationId="1" priority="0"/>
              <VideoLocation id="3" path="003349MA.mxf" typeId="5" locationId="1" priority="0"/>
           </VideoLocations>
        </DigitalAsset>
        <DigitalAsset available="true" som="20:28:49:05" dur="00:02:46:04" videoDurationMinutes="3" videoFormatId="11">
           <VideoLocations>
              <VideoLocation id="101" path="003349MA.mpg" typeId="1" locationId="1" priority="0"/>
              <VideoLocation id="101" path="003349MA.mpg" typeId="2" locationId="1" priority="0"/>
              <VideoLocation id="101" path="003349MA.mpg" typeId="8" locationId="1" priority="0"/>
           </VideoLocations>
        </DigitalAsset>
    </DigitalAssets>
    <SDataSection xmlns="http://mad.evs.com/search">
      <EventDate>2006-08-09</EventDate>
      <LogType>3</LogType>
    </SDataSection>
  </MainCategory>
  

  
  

  In this case, because HASPATH expression could be set to true, the value of the added node must be 1.

  
  

  Any help or advice how I should fight against that would be appreciated. I have no experience with XML and XQuery, I create my function through from trial and error of the doc.
  

  
  

  Thanks and regards, Pierre
  

  Hi Pierre,.

  You can use the if-then-else statement, like this:

  Insert the node

  {

  If ($d/MainCategory/DigitalAssets/DigitalAsset[@available="true' and @videoFormatId = '11'] / VideoLocations/Videorental [@typeId = '8'])

  then 1

  0 otherwise

  }

  After $d, MainCategory, SDataSection, EventDate

  XSLT can be an alternative to the XQuery Update in this case.

  Shree says:
  1. can differentiate you these XSLT, XPath and XQuery.

  XSL stands for EXtensible Stylesheet Language is a language of style sheet for XML documents. XSLT stands for XSL Transformations.
  XQuery is to XML SQL format to database tables. XQuery is designed to query XML data.
  XPath is used to navigate through elements and attributes in an XML document. XPath is a major element of trailer of the W3C XSLT - and XQuery and XPointer are both built on XPath expressions.

• OSB: xpath as a result of the XQuery output?

  Hello
  
  I have a related XML non-schema as input. Value of one of the tags will be 'KEYWORD'.
  I want a dynamic text 'Hello' instead of the KEYWORD.
  From now I convert XML to a string with fn - bea: serialize() and then create a fn: replace.
  
  Viz:
  Let $received_input: = KEYWORD < C > < D >/< d: > < / c >
  Let $convertedXML: = fn-serialize ($received_input)
  Let $temp_string: = fn:replace($convertedXML,"KEYWORD","hello")
  Let $final_output: = fn - bea:inlinedXML ($temp_string)
  return $final_output
  
  Now, notice that the xml entry still varies as * < Z > keyword / < z > * or keyword < B > < C > < D >/< d: > < E > keyword < /E > < / c > < / b > or anything, only 'KEYWORD' will be there for you.
  
  Because xml input varies, I don't have a diagram. What if I want to use to replace action by node contained in the variable received_input? I need to calculate the xpath of the node that has the value = KEYWORD. It is a dynamic calculation of xpath.
  
  I wonder if there is a feature of xquery that I could use in OSB for this? Basically idea is to contribute a value and function returns the xpath of the node which conntains the value.
  
  
  Thanks and greetings
  Patricia Kharwadkar

  Hi Patricia Kharwadkar,.

  You can do what you want using plain xpath...

  $input =

  
  b
  keyword
  d
  keyword
  
  

  $value = "Hello".

  Replace the Xpath = / / * [. = 'keyword'] variable = expression of $input = $value (replace content of the node) will give you...

  
  b
  hello
  d
  hello
  
  

  This works for any schema that the xpath expression is looking for content only.

  I hope this helps...

  See you soon,.

  No doubt.

  Based on the old account information, I guess will be a recurring element. So I would build an update (based on the 'position' / 'POSITION for ordinalite', in XPATH position() function via PL/SQL and their update (swap), the and at once so content still would have the same structure, iow 'XXX.) XX. " The content could be replaced and or split via 'SUBSTR' and 'REPLACE '.

  Here, is: whenever a character does not match with any character in the set match ([ab] here), looks like a character before it?

  So, the first character has been verified that is 'f' because it does not, a '<>' was placed before the "f".

  What is the internal work?

  You will find perhaps clearer to imagine a pointer that can be placed before or after the characters, from before the first character after the last character and to check if the model is on the right.

  When the pointer is before the 1st character, there is 0 the or BS on his right, so replace you these 0 characters with '<>' and increments the pointer.

  When the pointer is after the 1st character, but before the 2nd character, there are 3 has the right, if you replace these 3 characters with ', and move the pointer to the end of these 3 characters.

  ...

  When the pointer is between 11 and 12 characters, there are 2 a and b to the right, if you replace these 2 characters by '' and move the position of the pointer 2 to the right.

  When the pointer is after the 13 character (in other words, the last character), there is 0 a or b to his right, so replace you these 0 characters with '<>',

  Hello

  There is no standard XQuery function to do.

  Here are some alternatives:

  1 - construction of the entire XQuery expression dynamically
  2. using a user-defined function to access the items dealt with by the XPath expression
  3 - use excerpt function, but it is obsolete...

• create xmlindex structured with multiple columns reflecting different XPath expressions

  I run a XMLEXISTS query to return documents that contain a specific search template. The search model is based on two distinct XPATHS. I tried to create an XML Index structured to support the request. While I can make it work when I specify that a XPATH, I can't make it work when I specify both.

  Oracle version: 11.2.0.3

  extendeddata / / DESC

  Name                                      Null?    Type

  ----------------------------------------- -------- ----------------------------

  U NOT NULL VARCHAR2 (14)

  XMLCONTENT NOT NULL SYS. XMLTYPE BINARY STORAGE

  ROWINSERTDATE NOT NULL DATE

  XMLSIZE NOT NULL NUMBER (10)

  DATAIMPORTID NOT NULL VARCHAR2 (100)

  MESSAGEFLOWNAME NOT NULL VARCHAR2 (200)

  Table is partitioned by month on ROWINSERTDATE

  XMLType column stored as files secure.

  Here's the query...

  SELECT u, xmlcontent

  To extendeddata

  WHERE the XMLEXISTS ('declare namespace CAMT54 = "urn: iso: std: iso: 20022:tech:xsd:camt.054.001.02";)

  $p / CAMT54:Document / CAMT54:BkToCstmrDbtCdtNtfctn / CAMT54:Ntfctn [CAMT54:Acct / CAMT54:Id / CAMT54:IBAN = $iban]

  [and CAMT54:Ntry / CAMT54:CdtDbtInd = $ctddbtind]' Xmlcontent passing that 'p ',.

  "XXXXXXXXXXXXXXXXXXXXXX" AS "iban",.

  "DBIT" as "ctddbtind")

  AND rowinsertdate > = TO_DATE (' 2014-06-01 00:00:00 ',' ' SYYYY-MM-DD HH24:MI:SS)

  AND rowinsertdate < TO_DATE (' 2014-07-01 00:00:00 ',' SYYYY-MM-DD HH24:MI:SS');

  Here's the index...

  CREATE INDEX EXTENDEDDATA_XML_IDX1 ON EXTENDEDDATA (XMLCONTENT)

  INDEXTYPE IS XDB. XMLIndex LOCAL SETTINGS (' XMLTable EXTENDEDDATAIBAN)

  XMLNAMESPACES ("urn: iso: std: iso: 20022:tech:xsd:camt.054.001.02" as "CAMT54").

  "/ CAMT54:Document / CAMT54:BkToCstmrDbtCdtNtfctn / CAMT54:Ntfctn"

  COLUMNS

  IBAN VARCHAR (34) PATH "CAMT54:Acct / CAMT54:Id / CAMT54:IBAN".

  CTDDBTIND varchar (4) PATH "CAMT54:Ntry / CAMT54:CdtDbtInd" ');

  CREATE INDEXES SEPA_PAY. EXTENDEDDATAIBAN_IDX1 ON EXTENDEDDATAIBAN (IBAN, CTDDBTIND)

  TABLESPACE SEPA_PAY_BIG_IDX;

  exec dbms_stats.gather_table_stats (ownname = > 'SEPA_PAY', tabname = > 'EXTENDEDDATA');

  Can someone help me build an index for the query above?

  Thank you.

  This should work better, with the caveat explained above:

  SELECT t.*
  FROM extendeddata t
  WHERE XMLEXISTS('declare default element namespace "urn:iso:std:iso:20022:tech:xsd:camt.054.001.02";(::)
                 /Document/BkToCstmrDbtCdtNtfctn/Ntfctn[Acct/Id/IBAN=$iban]'
          Passing Xmlcontent,
                  'XXXXXXXXXXXXXXXXXXXXXX' AS "iban"
             )
  and XMLEXISTS('declare default element namespace "urn:iso:std:iso:20022:tech:xsd:camt.054.001.02";(::)
                 /Document/BkToCstmrDbtCdtNtfctn/Ntfctn[Ntry/CdtDbtInd=$ctddbtind]'
          Passing Xmlcontent,
                  'DBIT' as "ctddbtind")
  AND rowinsertdate >= TO_DATE(' 2014-01-01 00:00:00', 'SYYYY-MM-DD HH24:MI:SS')
  AND rowinsertdate < TO_DATE(' 2014-07-01 00:00:00', 'SYYYY-MM-DD HH24:MI:SS')
  ;
  

  (see how the predicates in each XQuery expression corresponds to the structure of the index)

  BTW, this kind of "DIY" XMLEXISTS works just as well.

  It emulates what we would have hoped for a single XMLExists in the first place:

  SQL> SELECT t.*
    2  FROM extendeddata t
    3  WHERE rowinsertdate >= TO_DATE(' 2015-06-01 00:00:00', 'SYYYY-MM-DD HH24:MI:SS')
    4  AND rowinsertdate < TO_DATE(' 2015-07-01 00:00:00', 'SYYYY-MM-DD HH24:MI:SS')
    5  AND EXISTS (
    6    SELECT null
    7    FROM XMLTable(
    8           XMLNamespaces(default 'urn:iso:std:iso:20022:tech:xsd:camt.054.001.02')
    9         , '/Document/BkToCstmrDbtCdtNtfctn/Ntfctn'
   10           passing t.xmlcontent
   11           COLUMNS IBAN      VARCHAR2(34) PATH 'Acct/Id/IBAN'
   12                 , CTDDBTIND VARCHAR2(4)  PATH 'Ntry/CdtDbtInd'
   13         ) x
   14    WHERE x.iban = 'XXXXXXXXXXXXXXXXXXXXXX'
   15    AND x.ctddbtind = 'DBIT'
   16  ) ;

• XPath to capture nodes between two nodes

  Hi all

  I met a problem a seemingly simple challenge of mine.

  I have the following xml code.

  Basically, I would like to capture the text between the begin-end blocks

  <? XML version = "1.0" encoding = "UTF-8"? >

  < document >

  < body >

  < paragraph >

  < run >

  < fld type = 'start' / >

  < / paragraph >

  So far, what I came up with is:

  WITH temp AS (
  SELECT 
         XMLTYPE ('<?xml version="1.0" encoding="UTF-8"?>
                    <document>
                       <body>

                          </paragraph>
                       </body>
                    </document>') AS xml_template
  FROM dual
  )
  SELECT x.*
    FROM temp
        ,XMLTABLE('//*/paragraph/run[fld/@type="begin"]/following-sibling::run[following-sibling::run[fld/@type="end"]]/text'
                  PASSING temp.xml_template
                  COLUMNS res varchar2(100) PATH '.'
                 )x
  

  Result:

  RES

  SAMPLE

  FIELD

  SAMPLE

  FIELD2

  SOME UNWANTED TEXT

  SAMPLE

  FIELD3

  Unfortunately what I wrote XPath is not good enough, because with regard to the text between the two blocs of start-end it still captures the unwanted text.

  My XPath knowledgege dept unfortunately not so I would appriciate annything you can help me with even an idea could get through on the edge.

  Thank you

  Steve

  Steve,

  XQuery can help in this case:

  SELECT x.*
  FROM temp
     , XMLTABLE('for $begin in /document/body/paragraph/run[fld/@type="begin"]
                 let $end := $begin/following-sibling::run[fld/@type="end"][1]
                 return $begin/following-sibling::run[. << $end]'
         PASSING temp.xml_template
         COLUMNS res varchar2(100) PATH 'text'
       ) x  ;
  

  Explanation:

  This FLWOR expression traverses all nodes 'start' in the document, finds the corresponding node of the 'end' and returns the sequence of "run" nodes follows 'begin' and above 'end '.

  If you want to concatenate all the fragments of text in a block, you can also do it directly, like this:

  for $begin in /document/body/paragraph/run[fld/@type="begin"]
  let $end := $begin/following-sibling::run[fld/@type="end"][1]
  return string-join($begin/following-sibling::run[. << $end]/text, "")
