XSLT choose/when problem.

[JPraveen Kumar]

Hi,

My xml looks like this. I need to select the elements with type = b.

 
<?xml version="1.0" encoding="UTF-8"?>
<a>
<subvertex xmi:type="a" xmi:id="123"/>
<subvertex xmi:type="b" xmi:id="234"/>
</a>
 

Can you please tell me what should be appropriate xslt:choose and xslt:when statements for this.

Instead of choosing inside for-each can I also apply the filter directly in the xsl:template match element?

Thanks Praveen.

You wouldn't need to use xsl:choose for that. An ordinary XPath expression like /a/subvertex[xmi:type='b'] would work, assuming you were interested in getting a list of subvertex elements. And assuming you had the xmi namespace declared.

And yes, you could use that in the match attribute of an xml:template element. Generally it's better (i.e. more in tune with the XSL language) to do that than to use procedural elements like xsl:for-each.
