Hi,
I am desperately hoping someone out there may be able to help me out with an
xquery app that I am building.
I have only just started with Marklogic and XQuery. It's going fairly well,
however I am having a really tough time in modifying the content of one of my
XML documents. I just cannot seem to get a change to an element to pick up.
Here's my process (I have had to take things back as basic as I could just to
try and get it working):
1. In Query console I have one tab open which queries for the contents of one
XML doc
xquery version "1.0-ml";declare namespace html =
"http://www.w3.org/1999/xhtml";xdmp:document-get("C:/Users/Paul/Documents/MarkLogic/xml/ppl/ppl/jdbc_ppl_3790.xml")
2. This brings back the document as below
<?xml version="1.0"
encoding="UTF-8"?><document><meta><rm_mimetype></rm_mimetype><rm_hasattachments>
false
</rm_hasattachments><rm_attachmentcount>...3790
</ppl_id><ppl_name>
Victoria Wilson
</ppl_name>
3. I now want to update the <ppl_name> element using XQuery but it's just not
happening. Here's the XQuery:xquery version "1.0-ml";declare namespace html =
"http://www.w3.org/1999/xhtml";;
let $docxml :=
xdmp:document-get("C:/Users/Paul/Documents/MarkLogic/xml/ppl/ppl/jdbc_ppl_3065.xml")/document/meta/ppl_namereturn
for $node in $docxml/* let $target :=
xdmp:document-get("C:/Users/Paul/Documents/MarkLogic/xml/ppl/ppl/jdbc_ppl_3790.xml")/document/meta/*[fn:name()
= fn:name($node)] return xdmp:node-replace($target, $node)
--- I am basically looking to replace the <ppl_name> element in the target
(3790) with the <ppl_name> element from the source (3065).
4. I run the Xquery - it completes without error (making me thing it has
worked) - return value reads "your query returned an empty sequence"
5. I then go back to the same tab as I used in step 1 and re-run the XQuery
used in step 1. The doc (3790) comes back but it STILL has Victoria Wilson as
the <ppl_name>
Can anyone please help? Perhaps the change needs committing? I just don't know.
Thanks for readingPaul
