Re: [xsl] trouble forming xpath expression with compound conditions

[Jörg Heinicke <joerg dot heinicke at gmx dot de>]

<xsl:value-of select="item[si/@id='3' and si='SI7']"/>

This statement will return the "sum" of all descendant text-nodes. But only 
from the first occurence of an <item> which fulfills your conditions.

More useful will be <xsl:apply-templates select=".."/>. With this the second 
condition 'select the <item> elements ...' will be fulfilled too.
