Hi list,
I have a performance problem with xalan:evaluate, first the scenario:
<somegeneratedxml>
<wishlist>
<item id="length">
<item id="weight">
<item id="speed">
</wishlist>
<data>
<item>
<length>100</length>
<height>100</height>
<weight>100</weight>
<color>red</color>
<speed>100</speed>
</item>
...
the wishlist items are dynamic and represent the set of data that I want to pick from each item in the data set, so I constructed for each wishlist/item a path with xalan:evaluate, which selects the elements from each data/item, but this is very slow. A better idea anyone?
Try
<xsl:key name="pick-ip" match="*" use="name()"/>
...
<xsl:template match="item">
<xsl:apply-templates selec="key('pick-it',@id)"/>
...
This can be extended to slightly more complicated cases.
