I used $x//text() in place of $x/text() as it try to get text from a direct child of the context element. i.e. head. that is the reason you are not seeing any result.
If you add any text inside <head> then your $x/text() will return the result. If you have to check the text present in any level, you need to use //. Use data and string like below, Please correct somebody if I am wrong here. let $x := <head xmlns="http://www.w3.org/1999/xhtml";> <script type="text/javascript"></script> <title> </title> </head> return data($x/node()[fn:normalize-space(.) ne '']) let $x := <head xmlns="http://www.w3.org/1999/xhtml";> <script type="text/javascript"></script> <title> </title> </head> return string($x/node()[fn:normalize-space(.) ne '']) Please note, performance will be poor in these cases Please don't use $x//string() or $x//data(), It will give you multiple results based on element hierarchy.
