Embarrassing XSLT newbie question

Hi,

I'm trying to delelop a stylesheet to add some tags to the top and bottom of HTML head and body nodes. So, I've started off with a stylesheet that looks like

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

  <xsl:template match="/">
    <xsl:apply-templates select="html"/>
  </xsl:template>
  
  <xsl:template match="html">
    <xsl:comment>
      <xsl:value-of select="' Entered html template '"/>
    </xsl:comment>
  </xsl:template>
</xsl:stylesheet>

which I apply to a random bit of HTML via xsltproc sample.xslt sample.html . The problem is that I don't get any output. I've flooded my code with various <xsl:comment> elements and as far as I can tell, my template for handling the root element is being entered, and that element has an html element as a child, yet when I <xsl:apply-templates select="html"/> , my <xsl:template match="html"/> desn't get executed. I am really confused.

I clearly have a blind spot - I've typed in the Hello, World example from chapter 2 of the O'Reilly XSLT book, and that behaves the same way as my own attempts - i.e. it doesn't work.

Of course, it could be that xsltproc doesn't work properly - I'm on Ubuntu 8.04 LTS - but a quick search on Google doesn't reveal dozens of other people saying the same sort of thing, so I think it's more likely that I'm being daft - again.

I'd _really_ appreciate a nudge in the right direction - ideally a gentle nudge :-)

Thanks,
Alan

here is to be found xslt parser

http://www.xmlsoft.org/XSLT/downloads.html

xsltproc is an alias or batch like
if parametres can be preset

xmllint.exe --xinclude --output %1 %2 %3

first.xml

<?xml version="1.0"?>
<root>
	<data>Daniweb</data>
</root>

first.xsl

<?xml version="1.0"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
	<xsl:output indent="yes" method="html"/>
	<xsl:template match="/">
		<html>
               <!--new root node in result.html -->
			<xsl:apply-templates select="root"/>
                        <!--node in first.xml to changed -->
		</html>
	</xsl:template>
	<xsl:template match="root">
		<xsl:comment>
			<xsl:value-of select="' Entered html template '"/>
		</xsl:comment>
		<body>
			<div>
				<xsl:value-of select="data"/>
			</div>
		</body>
	</xsl:template>
</xsl:stylesheet>

call to excute

xsltproc result.html first.xsl first.xml

result

<html>
  <!-- Entered html template -->
  <body>
    <div>Daniweb</div>
  </body>
</html>

Thanks for the reply. Heaven knows what I was doing wrong this morning, but I've given it another go and have got it working.

I had a problem because my input documents started with <html xmlns="http://www.w3.org/1999/xhtml" lang="en"> rather than with <html> and with the attributes, my stylesheet wouldn't output anything.

I can work around this with a process improvement - I'm going to add the attributes in the stylesheet rather than requiring them to be in the input documents, but I'm curious to know what the problem is, and how I can match elements with the above attributes.

Thanks again,
Alan

For a site that is written in XSLT and you can download both the XSLT and XML.

We generate all our pages out by xslt transform, unfortunately you just see the html rather than the xslt and xml.
