Re: Selection based on attribute value

Try something like these 2:

<xsl:value-of
select="//Portal:ScreenPreferences/Portal:Screen[@primary='true']/Portal:screenTitle"/>

<xsl:value-of
select="//Portal:ScreenPreferences/Portal:Screen[@primary='true']/Portal:screenColor"/>

(If you're already inside a template for Portal:ScreenPreferences, you
can obvoiusly shorten those expressions.)

The key bit is [@primary='true'].

When we've gotten to Portal:Screen, we have a node-list of all the
Portal:Screen nodes: then [@primary='true'] selects from that list just
those nodes that have a primary attribute with value "true" -- which
happens to be just the one node. Then it's simple to get it's children.
