Subject: Re: xsl:if syntax problem

<xsl:template match="entity">
  <xsl:if test="onClick='' or not(onClick='')">
    do processing
  </xsl:if>

You want to test whether onClick is empty or onClick doesn't exist? then not(onClick='') is the false expression.

Or in other words:
test=" A or not(A)" is always true.

The second part should be "not(onClick)" (without ='', because you would have again boolean in it).

But there is a shorter way too:

either

test="normalize-space(onClick)" (whitespaces are removed)

or

test="string(onClick)" (empty onClick but with whitespaces won't be ignored)

I think normalize-space(onClick) is the right one.

Joerg

However, this xsl does not appear to work. The xsl will run on the following
xml code.

  <entity id="e1">
    <description>Customers</description>
    <oncontextmenu></oncontextmenu>
    <image>images/book.gif</image>
    <imageOpen>images/bookOpen.gif</imageOpen>
    <onClick>http://www.google.com</onClick>

Any help, tips, links will be much appreciated,
Brian.
