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"/>

</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:
DECLARE @mockup TABLE(ID INT IDENTITY,YourXML XML);
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 (eg *:
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).
