XSLT displays too many results

mpetrane · May 30th, 2012, 03:26 PM

Hi,
I'm new at this and I appreciate any help you can give.

Example XML

Code:

<CATALOG>
	<CD>
		<TYPE>45 rpm</TYPE>
		<TITLE>Empire Burlesque</TITLE>
		<PRICE>10.90</PRICE>
	</CD>
	<CD>
		<TYPE>75 rpm</TYPE>
		<TITLE>Hide your heart</TITLE>
		<PRICE>9.90</PRICE>
	</CD>
	<CD>
		<TYPE>45 rpm</TYPE>
		<TITLE>Greatest Hits</TITLE>
		<PRICE>9.90</PRICE>
	</CD>
	<CD>	
		<TYPE>75 rpm</TYPE>	
		<TITLE>Still got the blues</TITLE>
		<PRICE>10.20</PRICE>
	</CD>
</CATALOG>

I have an XSLT for-each for each CD.
How do I get it to stop once it finds a 45 rpm.
The first time I want it to find the first 45 rpm, but the next time I want it to find the second, or third.

OUTPUT IS LIKE THIS KIND OF

Page 1
Blah Blah Blah
Blah Blha etc.

Price $10.90

Page 2
Blah Blah Blah
Blah Blha etc.

Price $9.90

I'm doing something like this but it always brings back both prices for the 45 rpm

Code:

<xsl:for-each select="/CATALOG/CD"/>
     <xsl:if test="type='45 rpm'"/>
           do some stuff here
     </xsl:if>
</xsl:for-each>

I know there is no BREAK an no LOOPS or VARIABLES, but I want it to break.

Any assistance is going to really help.
Thanks,
Mike

If you only want to process the first qualifying element, you don't need a for-each. Just do

Code:

<xsl:apply-templates select="/CATALOG/CD[type='45rpm'][1]"/>

and then write a template rule to process the selected CD.

I bought your book. I'm not smart enough yet to understand it however.

Thanks for the quick reply.

What does the [1] do?

If XX is a node-set, then XX[1] selects the first node in the node-set. Usually the first node in document order, unless XX is a reverse axis, e.g. preceding-sibling::*[1].
