[xquery-talk] Any problem with xmlns attribute on output html element?

Wed Mar 21 14:01:36 PST 2007

Hello,

The most likely possibility is that your FLWOR expressions use names 
that are not in any namespace. By adding the xmlns attribute without any 
prefix, you have just placed unprefixed names in the XHTML namespace. 
Since your names are not in any namespace, they no longer match.

For example:

<html>
{
    for $a in doc("a.xml")/a
    return $a
}
</html>

finds all the <a> elements in the a.xml document. On the other hand,

<html xmlns="http://www.w3.org/1999/xhtml">
{
    for $a in doc("a.xml")/a
    return $a
}
</html>

looks for all the {http://www.w3.org/1999/xhtml}a elements in the a.xml 
document. There aren't any, so it returns an empty sequence.

Without seeing your FLWOR expressions, it is impossible to know for sure.
