XMLTYPE extract some nodes

Hello
< book >
< book >
< id > 12 / < ID >
Oracle < name > < / name >
< / book >
< book >
< id > 15 / < ID >
< name > net < / name >
< / book >
< / books >

Please how can I retrieve the node containing the oracle book without the order of the element, in 10 g and 11 g

I mean that the result should be

< book >
< id > 12 / < ID >
Oracle < name > < / name >
< / book >

Thanks in advance

How about using the EXTRACT with following XPath function? :
book/books / [name = 'oracle']

The whole sample test case:
------------------------------------------------------------
CREATE TABLE testtab)
ID NUMBER PRIMARY KEY,
XML XMLTYPE
);
INSERT INTO testtab VALUES (1, XMLTYPE ('))

12
Oracle


15
NET

'));
COMMIT;

SELECT EXTRACT (xml, '/ books/book [name = "oracle"]') FROM testtab;

    With above document XML stored as varchar2 (4000) in 12.1.0.2.0, how can I retrieve and display the relevant information(sql_id,session_id,plan_hash,duration,read_bytes) based on the place where condition to filter on any node. For example.

    select * from (
SELECT EXTRACT (xmltype.createxml (a.report_summary), '//stats/stat[2]/text()').getstringval () AS elap_time from dba_hist_reports a WHERE component_name = 'sqlmonitor'
)
where elap_time > 100000000
/

    Here, I try to get sql_id, sql_exec_id, duration and other information stored in the xml document by applying the where on elapsed_time condition. But to do this, I must write the part EXTRACT for all nodes in the inline view which seems like very bad way of writing of XML query. Is there an easy way to get all the information of nodes so that I can freely apply node whatever, I want in the WHERE condition to filter the records? No better way to write the code then the code below?

    Don't know why, but it pays just 1 or 0. Even in your case his statement just 0 or 1 for all X 2 columns table.

    I guess I do something wrong in declaring XPATH for X 2 table but not able to find what it is.

    It makes account 0 or 1 because path expressions are bad.

    "For example: ' @name ="duration"

    This is a Boolean expression, not a step of XPath and so gets evaluated as such, which gives 0/1 for false/true values.

    What you need, it is something like this:

    SELECT x1.*

   , xmltable('/report_repository_summary/sql'

  • How to extract the node where the value of the node is the max in all of the XML document?

    Hello

    I have a transaction that refers to an xmltype in iRecruitment, containing multiple versions of the same node as follows:

    (only for the example data)



    {noformat} & lt; Transaction & gt;


    & lt; data & gt;


    & lt; ObjectVersionNumber & gt; 1 & lt; / object_version_number & gt;


    & lt; EO & gt;


    & lt; Attribute1 & gt; A & lt; / Attribute1 & gt;


    & lt; Attribut2 & gt; B & lt; / attribut2 & gt;


    & lt; /EO & gt;


    & lt; / data & gt;


    & lt; data & gt;


    & lt; ObjectVersionNumber & gt; 2 & lt; / object_version_number & gt;


    & lt; EO & gt;


    & lt; Attribute1 & gt; A & lt; / Attribute1 & gt;


    & lt; Attribut2 & gt; C & lt; / attribut2 & gt;


    & lt; /EO & gt;


    & lt; / data & gt;


    & lt; data & gt;


    & lt; ObjectVersionNumber & gt; X & lt; / object_version_number & gt;


    & lt; EO & gt;


    & lt; Attribute1 & gt;? & lt; / Attribute1 & gt;


    & lt; Attribut2 & gt;? & lt; / attribut2 & gt;


    & lt; /EO & gt;


    & lt; / data & gt;


    & lt; / Transaction & gt; {noformat}

    I can extract a value for FULL-TIME 1 or 2, is not a problem.
    However, how can I go on the selection of a value of an attribute below FULL-TIME X, where X is the maximum value of FULL-TIME in any node in the XML document?

    I tried to the last node corresponding to my way, but it is not always the case that the FULL-TIME max will correspond to this scenario.

    Any help would be greatly appreciated!

    Thank you very much, Pete

    Here is the result:

    Race 1 (getstringval):

    Race 2 (getstringval):

    Race 3 (getstringval):

    Replace getstringval with getclobval seems to fix the problem.

    By creating the xml as literal does not show the same problem.

    Probably a bug on this version.

    Kind regards.

  • XMLType extract query

    Hello:

    How to change the following query to get only the element with a given person_id? Actually, I have a CLOB containing an XML document. I thought that step 1 is to create a view, or something that casts of this column to an XMLType object, so I do that in the data of test here as well. If I do not need to do, it makes it very well.
    with base as ( -- Base XML
    select '<?xml version="1.0" encoding="UTF-8"?>
    <person_record_set>
    <person>
    <lname>Doe</lname>
    <fname>John</fname>
    <person_id>12345</person_id>
    </person>
    <person>
    <lname>Smith</lname>
    <fname>John</fname>
    <person_id>54321</person_id>
    </person>
    <person>
    <lname>Jones</lname>
    <fname>Mary</fname>
    <person_id>33333</person_id>
    </person>
    </person_record_set>' bdata
from dual
),
Q1 as ( -- We want it as an XMLType
select xmltype(bdata) xtdata 
from base)
-- End of test data setup
select '<rows>' || extract(xtdata,'//person') || '</rows>' from Q1
    Thank you

    You can use conditions on the xpath:

    with q1 as (select xmltype('
    
    
    Doe
    John
    12345
    
    
    Smith
    John
    54321
    
    
    Jones
    Mary
    33333
    
    ') xtdata from dual)
-- End of test data setup
select '' || extract(xtdata,'//person[person_id=12345]') || '' from Q1

    I don't like particularly the addition of '', though; that's what you do with this data? There are probably better ways to do this.

  • A parameter of xmltype extraction problem

    Hello
    I am using oracle 11g and I am trying to use an xmltype as input to an SP parameter, here's my SP:

    create or replace PROCEDURE ABC
    (FE_Param OF XMLType)
    AS
    BEGIN
    I'm IN
    (
    SELECT XMLTYPE. EXTRACT (VALUE (a),
    ' Root/FE_ID/text()').getstringval (LIKE FE_ID)
    TABLE
    (XMLSEQUENCE (FE_Param.EXTRACT
    ("/ FEData/Root")
    ) ) a )

    LOOP
    INSERT INTO table1
    VALUES (i.FE_ID);
    END LOOP;

    The XML parameter looks like this:
    <? XML version = "1.0" encoding = "utf - 8"? >
    < FEData >
    < root > < FE_ID > 900000031 < / FE_ID >
    < FE_ID > 900000032 < / FE_ID > < FE_ID > 900000050 < / FE_ID > < / root > < / FEData >

    Thank you

    Ok. Wasn't sure. Thank you for that clarification.

    .. .but please make an attempt with XMLTABLE XMLQUERY, XMLCAST (or CAST) and other XML functions that support XQuery and not to use the engine of 'old '... I hope that these features will keep things as it should...

    .. .If not... create an SR with support of Oracle on this issue. Changes, if you base your SR on these 'old' operators XML/SQL and functions that are her will not be able to help, mainly due to the fact that your last version and stuff like EXTRACT / getStringVal() etc. are announced officially discouraged in this 11.2.0.2.0 version. As far as I know the t.xmldata.extract, the xml_type.extract and the other syntaxes, outlaw count of 10.1 (although I know, he appealed to java / OO people kind).

  • XMLType.extract: result of split

    Hello

    I use this function of the soap_api.sql for web services.
    FUNCTION get_return_value(p_response   IN OUT NOCOPY  t_response,
                          p_name       IN             VARCHAR2,

  RETURN VARCHAR2 AS
-- ---------------------------------------------------------------------
BEGIN

        RETURN p_response.doc.extract('//'||p_name||'/child::text()',p_namespace).getstringval();

END;
    The problem is that it returns a large number of values, and they are all concatenated to the return value. Is there a way to divide all values with a separator or something?

    For example. It returns "TexasLos AngelesChicagoPhoenix" and I would like something like "Texas; Los Angeles; Chicago; Phoenix»

    I am using Oracle 11g

    Thank you

    Hello

    You can use the XMLQuery function and string-join (XPath 2.0).

    For example:

    SQL> DECLARE
  2
  3   xmldoc xmltype := xmltype(
  4  '
  5  Texas
  6  Los Angeles
  7  Chicago
  8  Phoenix

 12   p_name      VARCHAR2(30) := 'city';
 13   p_namespace VARCHAR2(100) := 'test';
 14
 15   v_result    VARCHAR2(100);
 16
 17  BEGIN
 18
 19   select xmlcast(
 20    xmlquery(
 21     ( 'declare default element namespace "'||p_namespace||'"; (::)
 22       string-join(//'||p_name||'/child::text(),";")' )
 23     passing xmldoc
 24     returning content
 25    )
 26    as varchar2(100)

 31
 32  END;
 33  /

Texas;Los Angeles;Chicago;Phoenix

    It works well on 11.2, not sure about 11.1.

    Another way, by blocking the part extracted outside XQuery.
    Perhaps it fits better into your actual design:

    SQL> DECLARE
  2
  3   xmldoc xmltype := xmltype(
  4  '
  5  Texas
  6  Los Angeles

  • Some nodes of property subVIs and graphics seem not to complete all actions unless I look at them.

    I have a few subVIs in use which take the server references to graphics and images and add sliders, establish the limits and the pixel values min/max value.  Sometimes a couple of sliders don't prepare you, or one of the limits will be bad, etc.  If I open the Subvi and place probes or preserve values to see what numbers are passed, everything is running and all of the sliders are defined.  I also had this problem outside a Subvi with a property node affecting 16-bit values min and max of pixels. I checked, and the same / correct are passed to all the nodes property, as are the correct references.  The Subvi always run correctly by operating later in the calling VI, only during initialization do they sometimes fail.

    Thank you

    Brendan

    So I tried to unifying the property node, but that has no effect.  It turns out be related to writing data in the chart before you set the sliders and the mini/maxi.  Even if the chart has not been set on autoscale, it seems that it is be re-scheduled somewhat when the data has been written.

    Thank you!

  • Having trouble getting Windows media player to recognize and extract some burned CD when I insert the CD, nothing comes up on the tab extract. I have licenses for all the protected songs and the same CD was ripped in the past by using media player.

    My computer has a virus and before I wiped it's own, I copied all my files to blank CD I was able to extract these CDs on my computer but they are in the WMA format and I want them in MP3 format. I changed the rip settings but when I put in the CD Ripper re - it, nothing comes tab extract. I tried to delete all the files in windows media player and my computer but media player doesn't always recognize the CD tab extract. I have restored my music files from the bin to WMA, but I really need to extract the songs in MP3 format. What can I do to get Windows to recognize and tear my CD? Any help is appreciated.

    Thank you!

    Make sure that there is no CD in the CD drive. Then, go to Options - confidentiality of WMP and click the button Clear the Caches . Restart WMP, and insert a CD you want to re - rip. Are you able to rip the CD now?

    If it still does not work, you can try to rip the CD from another user account (if necessary, create a new user account in the control panel). Afterwards, you can move the files ripped to MP3 to your own original account. Tim Baets

  • Is it possible to NAT some nodes, but not others?

    Basically, I want to give a public IP address to one of our nodes inside the firewall. I know I could give him a private address and NAT from the public to the private sector, but I want to give the node address and no NAT at all and keep all the benefits of a firewall. It is a PIX 501.

    Let me know if it is still possible.

    Thank you

    O

    Howdy,

    You can certainly. Use the following command to do this:

    NAT (inside) - 0 access list

    Then, create an ACL with the addresses that you do not want to be NAT'ed:

    10.1.2.0 ip access list allow 255.255.255.0 any
