• Conversion of extractValue XMLTABLE

  Hello world

  I recently discovered extractValue is obsolete and I am trying to convert my code XMLTABLE.

  Examples, I found on this forum and other places, I think I have the right to the syntax, but it does not return all the values of the XMLTABLE call.

  My version is: Oracle Database 11 g Enterprise Edition Release 11.2.0.3.0 - 64 bit

  SELECT xt.po_num, xt.vendor,

  extractValue (p_t.po_xml_data, ' / PurchaseOrder/PO_Num ',' xmlns = "http://tempuri.org/" ' ")

  OF p_t po_table,.

  XMLTable (XMLNamespaces (default 'http://tempuri.org/'), )

  ' / PurchaseOrder'

  PASSAGE po_table.po_xml_data

  COLUMNS

  po_num PATH VARCHAR2 (12) "PO_Num."

  provider path ACCESS of VARCHAR2 (12) "PO_Vendor") xt

  where p_t.po_xml_data_id = '366000000008143';

  The "extractValue" returns the number of PO for this record.  The other two columns are null.

  The XML data in the po_xml_data of XMLTYPE column in this record looks like this:

  "< PurchaseOrder xmlns = 'http://tempuri.org/" "xmlns: xsi ="http://www.w3.org/2001/XMLSchema-instance"> " "

  "< PO_Num xmlns:ns4 ="http://tempuri.org/"ns4:IsFlagged ="false"> 123454 < / PO_Num >"

  "< PO_Vendor xmlns:ns4 ="http://tempuri.org/"ns4:IsFlagged ="false"> HP < / PO_Vendor >"

  < / PurchaseOrder >

  I appreciate any help you can offer.

  Thank you

  Jack

  Hi Jack,

  You have the right XMLTABLE syntax.

  But I do not reproduce the behavior you describe.

  When I tried to run the query, I get:

  ORA-00904: "PO_TABLE." "" PO_XML_DATA ": invalid identifier

  Shouldn't this part: PASS po_table.po_xml_data

  read this instead: p_t.po_xml_data of PASSAGE?

  Once the problem is corrected, I have another error, which is, in my view, the real issue here:

  SQL> create table po_table (po_xml_data_id varchar2(30), po_xml_data xmltype);
  
  Table created.

  ERROR at line 1:
  ORA-19025: EXTRACTVALUE returns value of only one node
  

  After removing the EXTRACTVALUE call, we can see why the error occurred.

  Oracle retrieves the attribute node, as if it were an element, thus feeding two nodes to EXTRACTVALUE.

  This is a bug, always present in the most recent version of today (12.1.0.2), but it occurs only when the attribute is qualified namespace.

  SQL> SELECT xt.po_num, xt.vendor
    2         --, extractValue(p_t.po_xml_data, '/PurchaseOrder/PO_Num', 'xmlns="http://tempuri.org/"')

  Workaround: extract explicitly down to the text() node:

• ExtractValue, extracted, xmlsequence

  Could someone explain what extractvalue, xmlsequence and excerpt in the following query:
  

  select
     extractvalue(value(a),'Notebook/@Brand') As Brand
    ,extractvalue(value(a),'Notebook/@Model') As Model
  from prod_xml_tab b,
  table( xmlsequence( extract( demo_field,'Product/Notebook' ) ) ) a
  where demo_field is not null;

  I went through documentation and still don't get it and need some basic step by step explanations. for example, what actually GETS back for the first and second rows?
  the code in the table and the data is the following:

  for example, if the first row not contained that single product/Notebook (as the second row) there is need to use TABLE (XMLSEQUENCE...), right? Only extractvalue (demo_field, "Product/Notebook/@Brand") would suffice, right? xmlsequence is necessary because the first line has several entrances laptop and all these multiple information is always returned as a bunch of items for laptop (knots?) instead of relational lines, is that correct? then xmlsequence comes into play in order to convert every book of this bunch of laptops in topics separated more later converted into relational lines by SCOREBOARD operator. is it more correct?

  Thank you

  Yep, that sounds about right.

  With XMLTABLE, it would be something like this...

• Helps the namespace definition in extractvalue()

  Hello
  
  I use PL/SQL on Oracle Enterprise Edition 11.2.0.3.0 to call a Web service.
  
  I have an answer in a variable of type xmltype.
  
  I am trying to extract the md5sum value, but I can't specify the correct namespace for the extractvalue function.
  
  The XML response is
  < GetFileDetailsResponse xmlns = "http://10.1.0.1" >
  < GetFileDetailsResult >
  < FileDetails xmlns = "" >
  908655930beaa7ea3bca7a98adabfcf4 < md5sum > < / md5sum >
  < FileSize > 50929664 < / size >
  < FileLastModified > 2011 - 05 - 03T 12: 33:16 + 01:00 < / FileLastModified >
  < / FileDetails >
  < / GetFileDetailsResult >
  < / GetFileDetailsResponse >
  
  Simplfying this down I built the following select statement
  
  Select extractvalue (xmltype.createxml ("< GetFileDetailsResponse xmlns ="http://10.1.0.1">))
  < GetFileDetailsResult >
  < FileDetails xmlns = "" >
  908655930beaa7ea3bca7a98adabfcf4 < md5sum > < / md5sum >
  < FileSize > 50929664 < / size >
  < FileLastModified > 2011 - 05 - 03T 12: 33:16 + 01:00 < / FileLastModified >
  < / FileDetails >
  < / GetFileDetailsResult >
  (< / GetFileDetailsResponse > '), ' / GetFileDetailsResponse/GetFileDetailsResult/FileDetails/md5sum ','xmlns = "http://10.1.0.1" xmlns = "" ') md5 twice; "
  
  This property returns null
  
  However, if I remove two references in the XML namespace.
  
  Select extractvalue (xmltype.createxml ("< GetFileDetailsResponse >
  < GetFileDetailsResult >
  < FileDetails >
  908655930beaa7ea3bca7a98adabfcf4 < md5sum > < / md5sum >
  < FileSize > 50929664 < / size >
  < FileLastModified > 2011 - 05 - 03T 12: 33:16 + 01:00 < / FileLastModified >
  < / FileDetails >
  < / GetFileDetailsResult >
  ((< / GetFileDetailsResponse > '), ' / GetFileDetailsResponse/GetFileDetailsResult/FileDetails/md5sum ') double md5;
  
  908655930beaa7ea3bca7a98adabfcf4 - get the answer I want. Looks like I'm specifying the wrong namespace in the statement of extractvalue.
  
  Can someone suggest the statement correct extractvalue I should use. I looked at probably this too long - I'm misses what is obvious.
  
  Thank you for taking the time to read this,
  
  See you soon,.

  Hello

  Because the XPath of done refers to elements in a namespace and elements in no namespace, you must declare a prefix for the default namespace:

  SQL> select extractvalue(
    2    xmltype.createxml('
    3  
    4

    8  
    9  
   10  ')
   11  , '/ns0:GetFileDetailsResponse/ns0:GetFileDetailsResult/FileDetails/md5sum'
   12  , 'xmlns:ns0="http://10.1.0.1"'

  MD5
  --------------------------------------------------------------------------------

  But... extractValue is frowned upon in your version.
  You should now use XQuery functions:

  ---------------------------
  
  As my Xpath only points until the node - ParentPicklistValue and not the child nodes under it. That's why, when I try to interview the child nodes - / ParentPicklistValue/ListOfPicklistValue/PicklistValue/Code, I get the error mentioned above.
  
  REQUIREMENT
  -----------------------
  
  Can someone help me to receive the values of the mother and child values based on xml and query above.

  Hello

  It's a classic ;)

  You need a second XMLSequence who shreds the collection of PicklistValue in relational lines:

  select extractvalue(value(sr2), '/PicklistValue/Code', 'xmlns="urn:/crmondemand/xml/picklist"') AS Display
       , extractvalue(value(sr2), '/PicklistValue/DisplayValue', 'xmlns="urn:/crmondemand/xml/picklist"') AS Return
       , extractvalue(value(sr1), '/ParentPicklistValue/ParentDisplayValue', 'xmlns="urn:/crmondemand/xml/picklist"') AS parent_display
       , extractvalue(value(sr1), '/ParentPicklistValue/ParentCode', 'xmlns="urn:/crmondemand/xml/picklist"') AS parent_return
  from table(
         xmlsequence(
           extract( WEB_SERVICE( ... )
                  , '/soap:Envelope/soap:Body/ns:PicklistWS_GetPicklistValues_Output/ListOfParentPicklistValue/ParentPicklistValue'
                  , 'xmlns="urn:/crmondemand/xml/picklist"
                     xmlns:ns="urn:crmondemand/ws/picklist/"
                     xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"' )
         )
       ) sr1
     , table(
         xmlsequence(
           extract( value(sr1)
                  , '/ParentPicklistValue/ListOfPicklistValue/PicklistValue'
                  , 'xmlns="urn:/crmondemand/xml/picklist"' )
         )
       ) sr2
  ;
  

  What is your version of the database BTW?
  10.2 and upward, you can use the XMLTable.

  XMLTable will do what you want.

  For example, assuming XML_MESSAGE is a database of XMLType column:

  select x.*
  from your_table t
     , xmltable('/ATMWithDrawTrans/Trans/Tran'
         passing t.xml_message
         columns tran_date date   path 'TranDate'
               , amount    number path 'amount'
       ) x
  ;
  

  If your version does not support, see XMLSequence in the documentation.

  Hello

  You must apply the function extractValue on the XML fragment extracted with XMLSequence, not on the original document:

  SELECT extractvalue (x.column_value,'/ROW/USER_CMNT_ID'),
         extractvalue (x.column_value,'/ROW/OPERATOR_ID'),
         extractvalue (x.column_value,'/ROW/CMNT_TEXT'),
         extractvalue (x.column_value,'/ROW/CMNT_DTMS')
  FROM gt_xmltype_tab gt,
       TABLE(
         XMLSequence(
           extract(gt.xmlfile1, '/ROWSET/ROW')
         )
       ) x
  ;
  

  If you're on 10.2 or upward, prefer XMLTable:

  SELECT x.user_cmnt_id
       , x.operator_id
       , x.cmnt_text
       , to_date(x.cmnt_dtms,'DD-MON-RR','nls_date_language=english') as cmnt_dtms
  FROM gt_xmltype_tab gt,
       XMLTable(
        '/ROWSET/ROW'
        passing gt.xmlfile1
        columns user_cmnt_id number        path 'USER_CMNT_ID'

  Hello

  extractValue returns a scalar value (usually a text or attribute node) of a given node, not an instance of XMLType.

  So in your example, varDefinition is an empty element, extractValue gives a NULL value.

  Hello

  You don't need to get a counter for it.
  Here are two solutions depending on your version of the database, both based in break the XML in relational rows and columns:

  Pre-10 gr 2

  SELECT extractValue(x.column_value, '/Subject')
  INTO v_subject
  FROM lib_isbn_t t,
       TABLE(
         XMLSequence(
           Extract(
             t.isbn_payload,
             '/ISBNdb/BookList/BookData/Subjects/Subject'
           )
         )
       ) x
  WHERE t.lib_isbn_t_pk = 1
  ;
  

  10 gr 2 and +.

  SELECT x.subject
  INTO v_subject
  FROM lib_isbn_t t,
       XMLTable(
         '/ISBNdb/BookList/BookData/Subjects/Subject'
         passing t.isbn_payload
         columns subject varchar2(30) path '.'
       ) x
  WHERE t.lib_isbn_t_pk = 1
  ;
  

• Problem with table with XMLTYPE column extractvalue.

  I don't know there is a simple answer, but I have problems
  extract data from a column of xmltype type.
  I have two tables

  XMLTYPE TABLE
  

  descr dab_test

  Name

  A NUMBER
  NUMBER OF AB
  CLOB DATA

  and the myxml in dab_test column.
  
  When I run the following:
  
  SELECT extractvalue (OBJECT_VALUE, ' / PurchaseOrder/reference "")
  OF dab_xml;
  
  SBELL-2002100912333601PDT returned
  
  When I run the present:
  
  SELECT extractvalue (OBJECT_VALUE, ' / PurchaseOrder/reference "")
  FROM (select dab_test myxml);
  
  ERROR on line 1:
  ORA-00904: "OBJECT_VALUE": invalid identifier
  
  Why are the two different?
  
  Any help will be appreciated.
  
  Kind regards
  
  David

  In short, you want to

  SELECT extractvalue(myxml, '/PurchaseOrder/Reference')
  FROM dab_test;
  

  This difference is that for dab_xml, it has no columns defined for the table, so you are [OBJECT_VALUE | http://download.oracle.com/docs/cd/B28359_01/server.111/b28286/pseudocolumns006.htm#sthref830] as an alias for a column does not exist.

  With dab_test, you have a column that contains the XML, you must use this column instead of OBJECT_VALUE name.

• DICOM metadata - extractvalue returns the value of a single node

  Hello
  
  I have difficulties in getting the value of the objects with repeated elements. Specifically, I need to get the value of spacing of pixels in the following excerpt from xml.

  <DICOM_OBJECT>
  ..
       <DECIMAL_STRING tag="00181063" definer="DICOM" name="Frame Time" offset="900" length="2">0.0</DECIMAL_STRING>
       <CODE_STRING tag="0018106A" definer="DICOM" name="Synchronization Trigger" offset="910" length="10">NO TRIGGER</CODE_STRING>
  ..
       <DECIMAL_STRING tag="00280030" definer="DICOM" name="Pixel Spacing" offset="1660" length="22">0.003562</DECIMAL_STRING>
       <DECIMAL_STRING tag="00280030" definer="DICOM" name="Pixel Spacing" offset="1660" length="22">0.003562</DECIMAL_STRING>
       <UNSIGNED_SHORT tag="00280100" definer="DICOM" name="Bits Allocated" offset="1690" length="2">8</UNSIGNED_SHORT>
      <UNSIGNED_SHORT tag="00280101" definer="DICOM" name="Bits Stored" offset="1700" length="2">8</UNSIGNED_SHORT>
  ..
  </DICOM_OBJECT>

  Normally, I use the following query to get the value of spacing of pixels:
  

   select EXTRACTVALUE(t.dicom.metadata
                        ,'/DICOM_OBJECT/*[@name="Pixel Spacing"]'
                       ,'xmlns=http://xmlns.oracle.com/ord/dicom/metadata_1_0')  scale_factor
     from my_dicom_object t

  It works, but not when there are two elements. Then I get the error: "ORA-19025: EXTRACTVALUE returns the value of a single node.
  
  
  All I really need is to get the value of the first node with the name of "spacing of pixels. Despite the many examples available to do with traditional xml paths, I was unable to find an example that makes using XPATH search strings rather than direct tag structure.
  
  Can someone give an example?
