Re: [xsl] Plse Help! something to do with counter....

Hi, Thanks! It instead solve much of my problems but if I want to omit any one of the Resource element, for e.g I don't want to have a checkbox for the 3rd element but I still want to display other values of this element, and at the same time the value attribute of the checkbox will still be in consecutive numbers. position() don't seem to be able to work this way...

Sorry, if I didn't explain clearly. Thanks for your help!

Hi Justin,

Ah... I'm sorry - I misinterpreted your question.  Thanks for posting
more details.

So, you want to have a different input element for each Resource; each
Resource has an Index child which gives the name for the checkbox, and
you want each to have a distinct value.

That's actually a lot easier. Just apply templates to the Resource
elements:

<xsl:template match="/">
   <html>
      <body>
         <form method="GET" action="../servlet/takeLoan">
            <xsl:apply-templates select="List/Resource" />
         </form>
      </body>
   </html>
</xsl:template>

Now, the processor takes that set of Resource elements and sorts them
into a list (in document order) that it will process, called the
current node list.  You can have a template that matches the Resource
element to provide you with the output that you want for each of them.
Within this template, you can use position() to get the position of
the particular Resource element you're currently processing (the
current node) within the current node list.  And you can use that to
get the incrementing values that you want:

<xsl:template match="Resource">
   <div align="right">
      <input type="checkbox" name="{Index}" value="c{position()}" />
   </div>
   <br />
</xsl:template>

I hope that helps,

Jeni
