testing xslt parameters

bluegospel · 09-23-2011, 08:12 PM

Hi. I'm trying to find a means to run a simple xsl:if test in xslt, which when true, will set a value I can use in the output of the xslt stylesheet.

I found a somewhat relevant discussion, but I'm not sure of the accuracy of the following excerpt because the method doesn't work when I use it in another context:

I must admit at this point, that I have just realised the code I provided in my first post does work...

<xsl:if test="$page = 1">
do some tranformation
</xsl:if>

This is at: http://www.webmasterworld.com/forum26/235.htm

Although I'm not running a transformation inside the tags. I'm assigning values to some new parameters: eg,

PHP Code:



<xsl:param name="he_she">he</xsl:param>

I appreciate your help.

I wrote an app some years ago which generated xml data which was marked up by an xslt, I don't remember having any issues with xsl:if but I'll check when I get home and post a sample.

Here is an xslt test I have in some of my code where I check for a non-null value.

Code:

<xsl:if test="col[@field='level']!=''">
   <data field="level"><xsl:value-of select="col[@field='level']"/></data>
</xsl:if>

The col[@field='level'] would I suspect be equivalent to your $page

Hope that helps.

Thanks graemef. Either because I'm a newbie or very tired, or both, I don't quite understand what: col[@field='level'] is. I'll look at this again tomorrow. Thanks again!

The col[@field='level'] is just taken from my input file I have a col tag <col> with a param field with a value of field, thus <col field='level'></col> or <coll field='level'>L0</col> and I want to end up with <data field='Level'>L0</data> if and only if I have a non null value in the first example.

Sorry I lied, must have been a different app I was thinking of - this one only has xsl:when :-

Code:

...
<xsl:when test="contains(job_status, 'No Data')">
	<tr bgcolor="#EE6633">
		<td><xsl:value-of select="server_name"/></td>
		<td><xsl:value-of select="job_name"/></td>
		<td><xsl:value-of select="job_status"/></td>
		<td><xsl:value-of select="start_date"/></td>
		<td><xsl:value-of select="time_started"/></td>
		<td><xsl:value-of select="bytes_processed"/></td>
		<td><xsl:value-of select="elapsed_time"/></td>
		<td></td>
	</tr>
</xsl:when>
...

I've not forgotten this issue. I'm kind of pressed with others right now. I will certainly return to this soon.
