Recursive Loop in XSLT file

mhkay · April 5th, 2010, 05:02 PM

Your "XML" files are not in fact XML: they have two top-level elements, <def> and <Lineage>, which is not allowed. I'll pretend the <def> element is not there, because it only complicates matters.

Then you can replace this code:

Code:

<xsl:if test="//Lineage/sample_001">
  <tr>
    <td valign="top">
      <p class="intitule">1</p>
    </td>
    <td  width="200">
      <dir class="new"><xsl:value-of select="//Lineage/sample_001/time"/></dir>	
    </td>

with something like this:

Code:

<xsl:for-each select="Lineage/*">
  <tr>
    <td valign="top">
      <p class="intitule"><xsl:value-of select="position()"/></p>
    </td> 
    <td  width="200">
      <dir class="new"><xsl:value-of select="time"/></dir>	
    </td>  
    ... etc ...

(I assume "dir" is another typing mistake for "div", but that's a minor detail).

Please find the needed changes below:
1. Add a version (1.0 or 2.0) attribute to <xsl:stylesheet ...
2. Change xmlns:xsl="http://www.w3.org/TR/WD-xsl" to xmlns:xsl="http://www.w3.org/1999/XSL/Transform"

Find the complete stylesheet (with Mike's ideas) below. Copy the whole below code and paste into your current TP.xsl, and then check:

Code:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns="http://www.w3.org/TR/REC-html40">
 
<xsl:template match = "/">

  .new { font-size: 8px; font-family: Verdana, Arial; }

Its because of xmlns:xsl="http://www.w3.org/TR/WD-xsl" you got that "Unknown method. -->position()" error. Try now.

>xmlns:xsl="http://www.w3.org/TR/WD-xsl

Sorry I failed to spot that. Until a few years ago that used to be one of the first things I looked for - but I haven't seen anyone make this mistake for a long time. This namespace was used by Microsoft's very first XSLT-like implementation, released in 1998 before the W3C spec came out the following year, and it has been obsolete for at least ten years. The language has many differences from XSLT (the absence of the position() function being one example) and it's impossible to obtain documentation for it any more. Because there is so little information about it, it's unusual these days for beginners to fall into the trap of using it.

Hello 2 all,

Thank you for posting this solution for me. I am getting my output but i want to do some enhancement. I want to create such type of file in which after clicking on some text the table will be show and whenever I click on the same text the table will be hide.

Also I want to run this XML file in Linux. And in Linux is not support IE. So how to run my XML file in Linux operating system.

Please give me suggestion.

Thanks,
Dhrumil

a) sounds like you want some javascript UI in your output. This has nothing to do with XSLT.

b) Have you tried running it in Firefox? Either that or move to some command line based XSLT processor (such as Saxon perhaps) that runs on any platform.

dhrumil · April 12th, 2010, 10:28 PM

Sir,

a). ok. But i see one xml file in that this kind of function is used and they used xsl:eval for that.

b). yes sir. I tried it in Firefox and also I install the plug-in "xsl result" in Firefox with the hope that the xml file can run in Firefox. But still contain the error - "Error loading stylesheet: Parsing an XSLT stylesheet failed."
Can you just explain how to use this "Saxon" in XML file with a very small example.

Dhrumil.

> they used xsl:eval for that

As I explained, xsl:eval is not an XSLT instruction. It is an instruction in an obsolete Microsoft language dating from 1998, which I refer to as WD-xsl. "They" might have been using this language, but you are not.

> Can you just explain how to use this "Saxon"

Saxon doesn't work in the browser, it is a standalone product. The easiest way for someone with no experience to use it is to download kernow from http://kernowforsaxon.sourceforge.net/
