Hello.
Forgive me for asking newbie questions, but it's only because I'm a newbie :)
I want to have my XSL stylesheet evaluate to see if a tag exists or the
value is blank. How do I do this using <xsl:if> or <xsl:when> ?
For example, take the following schema:
<library>
<book>
<name>Hound of the Baskervilles</name>
<author>Sir Arthur Conan Doyle</author>
</book>
<book>
<name>A Dying man's prayer</name>
</book>
<book>
<name>XSLT Programmer's Reference</name>
<author>Michael Kay</author>
</book>
</library>
In the second record, the <author> data is not available. I want to check
for this (or the tags being empty) and then conditionally produce the
output. What would be the best way to do this?
Thanks for your help.
