Re: [xsl] Variable : string or temporary tree

["Siarhei Biarozkin" <sberyozkin at zandar dot com>]

Hi,
When testing whether the variable was a tree or not, I meant to say
$treeTest/node/*, that is I'd like to test whether a variable contains
element children, not any childtren, like text.
Thanks, S.Biarozkin
