Hi Kashif,
Why not treat your XML as XML instead of a string. Then you can just use
XPath. Something like:
let $document :=
<report>
<body>
<row>
<ChapterTitle>Front Matter</ChapterTitle>
</row>
</body>
</report>
return $document//ChapterTitle
=>
<ChapterTitle>Front Matter</ChapterTitle>

Subject: [MarkLogic Dev General] Unable to get the value of Element Š.
Hello Everyone, I am having a problem extracting value from an element
Here is the XML on which I am trying to run my query
Let $document := "<report>
<body>
<row>
<ChapterTitle>Front Matter</ChapterTitle>
</row
</body>
</report>"
These are the functions that I have written to extract the value of the
"ChapterTitle" Tag
declare function oxy:getHierarchyElements() {
let $TagName := "Chapter Title"
(:removing the space between Chapter and Title:)
let $tokenizedString := fn:tokenize(($TagName), '\s')
let $concatString := fn:concat($tokenizedString[1],
$tokenizedString[2])
return
element {$concatString} {''}
};
declare function oxy:getLevel($document as xs:string){
let $file := doc($document)
let $hierarchy := oxy:getHierarchyElements()
return
$file/report/body/row/$hierarchy
};
When I call oxy:getLevel($oxy:document) I get <ChapterTitle/> instead of
"Front Matter" from the XML file.
If I replace $file/report/body/row/$hierarchy with
$file/report/body/row/ChapterTitle I get the correct value.
Thanks for your help in advance
