Xquery Empty values

803630Feb 8 2011 — edited Feb 8 2011
How can I check this?

<soap:Header xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:contextid></soap:contextid>
</soap:Header>


I tried data($header/*:contextid) != ' ' but this is not returning true.

Is there any function to check this empty value?Should I use straing length only?

Thanks.
