Regular Expression search

[Howard Katz]

I'm betting that Eduardo's question is simply, "How do I find elements whose
contents begin with "MyNameIs"? and that he's simply using subTagA and
subTagB as examples representing *any* named containing element.

Firstly, it's not good XML design to use structured names for elements.
Rather than have two elements <subTagA> and <subTagB> it's better design to
use <subTag type="A"> and <subTag type="B">. But of course you sometimes
have to query badly-designed XML.
 
Secondly, you don't actually need regular expressions (though you can use
them if you want: see the matches() function). You can achieve this using
starts-with:
 
//*[starts-with(name(), 'subTag')][starts-with(., 'MyNameIs')]

Hi everyone,
lately I've been trying to build a xquery search that contains regular
expressions to get my result, but I couldnt make it. So I would like to know
how to search within a xml structure for some generic tags. For example: 
 
This xml:
 
<tagA>
    <subTagA>MyNameIsEduardo</subTagA>
</tagA>
<tagB>
    <subTagB>MyNameIsElarrat</subTagA>
</tagB>
 
How do I search for subTags that begins with "MyNameIs" and ends with
anything else so I can have both subTags on my result? Thanks in advance,
 
 
Eduardo Elarrat
