Generate Index.html page

tombliboo · February 11th, 2011, 07:49 AM

Hi

I'm generating the webpages for my website as per my code below, I'm having difficulty generating an Index.html page to go alongside these files, can anyone help?

Code:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="2.0">
<xsl:output method="html" indent="yes" name="html"/>
<xsl:template match="/">

<html>
	<style type="text/css">
		table {		border: solid 3px #000000;}		             th,td {		border: solid 3px #000000;}
	</style>			
	<body>				
	<table><th>Title</th><th>Sub Department</th><th></th>
		<xsl:apply-templates select="departments"/>
	</table>
	</body>
</html>

	</xsl:template>
		<xsl:template match="department">
		<xsl:apply-templates select="department"/>
	</xsl:template>

	<xsl:template match="department">
		<xsl:apply-templates select="subdepartment">
		<xsl:with-param name="title" select="title"/>
		</xsl:apply-templates>
	</xsl:template>

	<xsl:template match="subdepartment">
		<xsl:param name="title"/>
		<xsl:variable name="subdept" select="(.)"/>
		<xsl:variable name="filename" select="concat('output/',$title,' - ',.,'.html')"/>
		<tr><td><xsl:value-of select="$title"/></td>
		<td><xsl:value-of select="concat(.,'.html')"/></td>
		<td><a href="{$filename}">select</a></td></tr>

		<!-- webpages in html file -->
		<xsl:result-document href="{$filename}" format="html">

		<html>
			<body>
                                      <!-- my page code sits here-->
			</body>
		</html>
		</xsl:result-document>
	</xsl:template>
</xsl:stylesheet>

This generates my pages in the form of:

Department 1 - Sub Department 1.html
Department 1 - Sub Department 2.html
Department 2 - Sub Department 1.html
Department 2 - Sub Department 2.html

...and so on. I would like an Index which for the time being just includes hyperlinks to each page, and preferably a higher level link for each department which takes you to the first sub department within it.

I'm still trying to achieve this but in the meantime any assistance is much appreciated, my current attempts fail with errors such as:

Cannot write one than one result document to the same URI;
Or my variables store both sub departments in the same string

By the way I'm parsing this stylesheet through Saxon.

Many thanks

If you have code that generates an error then please show us the code generating that error and the exact error message. And of course we need to see an XML input sample.
If you want to output data from some nodes in different result documents then using modes on your templates can help.

Example of input xml:

Code:

<?xml version = "1.0" encoding = "UTF-8"?>

<departments>
	<department>
		<title>Department 1</title>
		<subdepartment>Dept 1 Sub Dept 1</subdepartment>
		<subdepartment>Dept 1 Sub Dept 2</subdepartment>
	</department>
	<department>
		<title>Department 2</title>
		<subdepartment>Dept 2 Sub Dept 1</subdepartment>
		<subdepartment>Dept 2 Sub Dept 2</subdepartment>
	</department>
	<department>
		<title>Department 3</title>
		<subdepartment>Dept 3 Sub Dept 1</subdepartment>
		<subdepartment>Dept 3 Sub Dept 2</subdepartment>
	</department>
</departments>

The code I'm currently working on I have positioned immediately after the last result-document tag in my above stylessheet:

Code:

<!-- Creating the index file-->
<xsl:result-document href="output/index.html" format="html">
<html><head><title>Index Page</title></head>
	<body>
	<xsl:for-each select="departments/department/subdepartment">
		<xsl:variable name="varDept" select="../title"/>
		<a href="'{$varDept}, - ',{.}'.html"><xsl:value-of select="concat($varDept,' - ',.,'.html')"/>
		</a><br/>
	</xsl:for-each>
	</body>
</html>		
</xsl:result-document>

This generates a blank index.html, only two of the sub department pages where there should be 16 (and works if I remove my Index creating code) and returns the error:

Error at xsl:result-document on line 44 of copystylesheet.xslt:
XTDE1490: Cannot write more than one result document to the same URI:

NB: line 44 is:

<xsl:result-document href="webpages/index.html" format="html">

Correction:

NB: line 44 is:
<xsl:result-document href="output/index.html" format="html">

If you put your
<xsl:result-document href="output/index.html" format="html">
into a template for an element which exists multiple times (like your subcategory elements) then of course your code tries to create the same index.html multiple times. That is not possible. So you need to restructure your code to make sure you create the document only once. As already suggested, in my view using modes is the right way or at least one way to achieve that e.g.

Code:

<xsl:template match="/">
  <xsl:result-document href="output/index.html" format="html">
    <xsl:apply-templates mode="index"/>
  </xsl:template>
  <!-- put other code here -->
</xsl:template>

<xsl:template match="departments" mode="index">
  <html>
    <head>
      <title>Department index</title>
    </head>
    <body>
      <ul>
        <xsl:apply-templates select="index"/>
      </ul>
    </body>
  </html>
</xsl:template>

<xsl:template match="subdepartment" mode="index">
   <li>
     <a href="output/{../title}{.}.html">
        <xsl:value-of select="."/>
     </a>
   </li>
</xsl:template>

<!-- other templates here for other content and/or other modes -->

</xsl:template>

Untested sample, and I am not sure I have used the proper URL in the href attribute you are constructing in your other code but it should give you an idea how to approach that to avoid the error you have described.

Thanks cracked it!
