Re: [xsl] No Duplicate Contain() is Allowed?

["Jesper Tverskov" <jesper@xxxxxxxxxxx>]

1. Your XML is not well-formed, look at:
 <publisher>Oreilly</publisher

2. Commenting out the last xsl:if does not make any difference when I
test with SAXON 9B.

3. The contains() function is for testing a string. But your xml
element contains mixed content that is both other elements and text
nodes.

It is not a good idea to mark up data as mixed content.

This is much better:
<book>
	<name>XSLT 2.0: From Beginning to Professional</book>
	<topic>XML</topic>
	<publisher>Wiley</publisher>
</book>

Cheers,
Jesper Tverskov
