Re: [xsl] Comparing nodes in axis

[xptm <xptm@xxxxxxx>]

Well, the "else" part is cut&paste, so i'm not writing more code... but
the important here is the execution of code without necessity, so i'll
change to the choose/when/otherwise.

Your sugestion of using

<xsl:value-of select="number(parent::menu=(//menu)[$pos])"/>

is very neat. However i cant use it cause the "otherwise" is not 0 but
instead the prior value of the node, that could be 1 or 0.

But ofcourse, you could not guess that...

Thanks again.
