T-SQL Find node with matching text and extract value from sibling node in XML field - sql-server

I've a table with an xml field having content like this:
<ContentBlock xmlns="http://corp.com/wdpr/ContentBlock">
<key xlink:href="tcm:0-133036" xlink:title="entityCard" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink"/>

</media>
</ContentBlock>
My goal is to have a query where I can find (for example) the <p> that contains the text "Make a Friend", then get the xlink:href of the <name> element in the same <section> tag.
I tried a few options like in this posts: here and here but I'm not getting the results I need.
This doesn't work
SELECT a.value1,
x.XmlCol.value('(section/content/p)[1]','VARCHAR(100)') AS SendMethod
FROM #test a
CROSS APPLY a.AppConfig.nodes('/ContentBlock') x(XmlCol)
WHERE x.XmlCol.exist('section/content/p[contains(.,"Make a Friend")]') = 1
How can I get it?
Thanks in advance. Guillermo.


Try it like this:

INSERT INTO #mockup VALUES

-First I declare a variable to make the search-string dynamic:
DECLARE #SearchFor VARCHAR(100)='Make a Friend';
--Your XML has a default namespace in the outermost element.
--What makes things a bit weird: There is another default namespace on the element <p>
--We can declare this with a speaking prefix
WITH XMLNAMESPACES(DEFAULT 'http://corp.com/wdpr/ContentBlock'
,'http://www.w3.org/1999/xlink' AS xlink
,'http://www.w3.org/1999/xhtml' AS InnerDflt )
SELECT YourXML.value('(/ContentBlock/section[(content/InnerDflt:p/text())[1]=sql:variable("#SearchFor")]/name/#xlink:href)[1]','nvarchar(max)')
FROM #mockup
The query runs as this:
Start with <ContentBlock>. Look for a <section>, where the text() of <p> below <content> is the search-string. Important: At this stage we are still on the level of <section>. So we can continue the XPath with <name> and find the attribute there.


Shnugo stole my thunder but I'm still posting what I put together as it will work as well and demonstrates a few tricks (e.g. *: for when you're too lazy to add the correct namespace syntax) ;). I was going to mention the use of sql:variable to pass a SQL variable into your XPath expressions - shnugo's post demonstrates how to do that (it's missing in what I'm posting).

Add variable as attribute to subnodes of a XML in TSQL

I am trying to add the value of a pre-defined variable to each individual subnode of my XML. I found this question SO Question and its answer, which looks pretty neat to me.
However, I can't use the variable #modification_time as an input for the attribute.
DECLARE #xml XML=
N'<ContentTemplate>
<Tab Title="Lesson">
<Section Title="Lesson Opening" />
<Section Title="Lesson/Activity" />
</Tab>
<Tab Title="Wrap Up and Assessment">
<Section Title="Lesson Closing" />
<Section Title="Tracking Progress/Daily Assessment" />
</Tab>
<Tab Title="Differentiated Instruction">
<Section Title="Strategies - Keyword" />
<Section Title="Strategies – Text" />
<Section Title="Resources" />
<Section Title="Acceleration/Enrichment" />
</Tab>
<Tab Title="District Resources">
<Section Title="Related Content Items" />
<Section Title="Other" />
</Tab>
</ContentTemplate>';
I can't figure out if it's possible and how to add the variable value to the subnode.
DECLARE #modification_time nvarchar(30);
SET #modification_time = FORMAT(CURRENT_TIMESTAMP,'yyyy-MM-ddTHH:mm:ss' ) ;
SET #xml=#xml.query(
'<ContentTemplate>
{
for $t in /ContentTemplate/Tab
return
<Tab Title="{$t/#Title}" PortletName="CommunitiesViewer" ModificationTime="VariableValuehere" >
{$t/*}
</Tab>
}
</ContentTemplate>');

xidel: add object into json array

I want extract some information on a website. For this, i use xidel.
I use this command line:
xidel --template-file template.xml --dot-notation=on
and here my template file :
<actions>
<action>
... code before ...
<page url={$url}/>
<pattern>
<div class="row p-r-15 p-l-15 contenu-collec">
{$collection := []}
<t:loop>
{$manga := {}}
<div univers="1">
<div class="post-block collec-titre">
<h2 class="post-title detail-objets">{$manga.title:=.}</h2>
<div>
<input>{$manga.value:=#value}</input>
</div>
</div>
</div>
<!--<call action="test"/>-->
{$collection := $collection.push($manga)}
</t:loop>
</div>
</pattern>
<loop var="t" list="$collection">
<call action="test"/>
</loop>
</action>
<action id="test">
<page url="http://site">
<post name="editions" value="{$t.value}"/>
<post name="action" value="collec_objets_serie"/>
<post name="univers" value="1"/>
<post name="user_id" value="{$userid}"/>
<template>
<!-- <div style="display:block;">{$t.test}</div> -->
<t:loop>
{$t.tome := {}}
<a>{t.tome.url:=#href}</a>
</t:loop>
</template>
</page>
</action>
In the loop i create a object $manga. How to add this object to the $collection array ?
I have tried
{$collection := $collection.push($manga)}
but don't work.

Replace XML Span Element with Inner text of Span Tag in SQL Server

Replace span Element with its inner text whose class is "TAGGED_ITEM " in multiple rows with a column of type XML
<Item title="1234" xmlns="http://www.imsglobal.org/xsd/imsqti_v2p2">
<ItemBody>
<div class="item_text">
<div>
<span class="TAGGED_ITEM " id="c1_ae1">This is a map on a grid.</span>
<span class="TAGGED_ITEM " id="c1_ae2"> It shows a car.</span>
</div>
<span class="TAGGED_ITEM " id="c1_ae3"> It shows a car on Road.</span>
</div>
</ItemBody>
</Item>
Once Element is updated it should looks as below.
<Item title="1234" xmlns="http://www.imsglobal.org/xsd/imsqti_v2p2">
<ItemBody>
<div class="item_text">
<div>
This is a map on a grid.
It shows a car.
</div>
It shows a car on Road.
</div>
</ItemBody>
</Item>

This question had a particular namespace problem which, probably, had aroused the question. Eliminating namespaces on the match= does solve the problem. So an identity transform and a namespace-neutral matching gives the desired result:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="node()|#*">
<xsl:copy>
<xsl:apply-templates select="#*|node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="*[local-name() = 'span']">
<xsl:value-of select="text()" />
</xsl:template>
</xsl:stylesheet>
Result:
<?xml version="1.0"?>
<Item xmlns="http://www.imsglobal.org/xsd/imsqti_v2p2" title="1234">
<ItemBody>
<div class="item_text">
<div>
This is a map on a grid.
It shows a car.
</div>
</div>
</ItemBody>
</Item>

How do you get a node that contains a child node with a given attribute value in an XML document using sql server?

I'm working on parsing XML documents using SQL Server 2008. I'm a complete noob and I was wondering if I can get help from you guys.
I have an XML document like the one below and I want to get the "section" node where the "code" node has val=5.
<root>
<section>
<code val=6 />
...
</section>
<section>
<code val=5 />
...
</section>
<section>
<code val=4 />
...
</section>
</root>
So the result should be:
<section>
<code val=5 />
...
</section>
I tried doing this, but it didn't work:
select #xml.query('/root/section')
where #xml.value('/root/section/code/#val,'int')= '5'
I also tried this:
select #xml.query('/root/section')
where #xml.exist('/root[1]/section[1]/code[#val="1"])= '1'
Any ideas? Thanks in advance.

You could use this query:
DECLARE #x XML=N'
<root>
<section atr="A">
<code val="5" />
</section>
<section atr="B">
<code val="6" />
</section>
<section atr="C">
<code val="5" />
</section>
</root>';
SELECT a.b.query('.') AS SectionAsXmlElement,
a.b.value('#atr','NVARCHAR(50)') AS SectionAtr
FROM #x.nodes('/root/section[code/#val="5"]') a(b);
Results:
SectionAsXmlElement SectionAtr
------------------------------------------- ----------
<section atr="A"><code val="5" /></section> A
<section atr="C"><code val="5" /></section> C

Instead of where you can apply the constraint in an XPath predicate:
#xml.query('/root/section[code/#val=5]')

SQL XML Insert multiple elements

Please help! I have a field of xml within a database. I am trying to insert a new element for each element in the field. E.g:
<some-element>
<a> </a>
<b> </b>
</some-element>
<some-element>
<a> </a>
<b> </b>
</some-element>
would insert element c and go to:
<some-element>
<a> </a>
<b> </b>
<c> </c>
</some-element>
<some-element>
<a> </a>
<b> </b>
<c> </c>
</some-element>
I know I can use #fieldname.modify('insert #CElement into (/some-element)[1]') but this only changes the first element! I want to repeat this for all elements.
Any help would be very much appreciated! (I am using SQL server 2008)
Moved from answer:
Thank you for your reply! Perhaps it would help if I was more specific... I am describing a simple table of data within the xml. I am trying to add a new column. I can add the column within the column descriptions but I need to add the column element to all the rows. (It would not be a simple task to change the structure and I would like to avoid this!) E.g:
<Table>
<Columns>
<Column ID="0">
<Column-Name>0NAME</Column-Name>
</Column>
<Column ID="1">
<Column-Name>1NAME</Column-Name>
</Column>
<Column ID="2">
<Column-Name>2NAME</Column-Name>
</Column>
<Column ID="3">
<Column-Name>!!!! THIS COLUMN IS BEING ADDED !!!!!</Column-Name>
</Column>
</Columns>
<Rows>
<Row ID="0">
<C ID="0">0 contents here</C>
<C ID="1">0 contents here</C>
<C ID="2">0 contents here</C>
<!-- NEW COLUMN NEEDS TO BE CREATED HERE -->
</Row>
<Row ID="1">
<C ID="0">1 contents here</C>
<C ID="1">1 contents here</C>
<C ID="2">1 contents here</C>
<!-- NEW COLUMN NEEDS TO BE CREATED HERE -->
</Row>
<Row ID="2">
<C ID="0">2 contents here</C>
<C ID="1">2 contents here</C>
<C ID="2">2 contents here</C>
<!-- NEW COLUMN NEEDS TO BE CREATED HERE -->
</Row>
</Rows>
</Table>

You can recreate your XML, e.g.:
declare #x xml = '<some-element>
<a>1</a>
<b>2</b>
</some-element>
<some-element>
<a>3</a>
<b>4</b>
</some-element>'
select #x.query
('
for $e in some-element
return
<some-element>
{ $e/a }
{ $e/b }
<c/>
</some-element>
')

Adapting the answer provided by Kirill Polishchuk to the new XML structure:
select #XML.query
('
for $c in Table/Columns
return
<Table>
<Columns>
{ $c/* }
</Columns>
<Rows>
{
for $r in Table/Rows/Row
return
<Row>
{ $r/* }
<C ID="3"/>
</Row>
}
</Rows>
</Table>
')
