Using Tidy to correct XSL templates.

Hello,

I'm currently looking to use Tidy as a method of cleaning up XSL
templates, if possible. To test it out, I have a very simple stylesheet:

<?xml version="1.0"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">


<img src="/members/images/header.jpg">

test



<xsl:for-each select="/root/page">
<xsl:value-of select="." />
</xsl:for-each>

</xsl:template>
</xsl:stylesheet>

Pretty simple. It contains the two most common errors that people do
when trying to create an XSL template

My problem is twofold:

1) If I just try and parse XML in this file, I get a result like this:

<?xml version="1.0"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">

<img src="/members/images/header.jpg">ok?


<xsl:for-each select="/root/page">
<xsl:value-of select="." />
</xsl:for-each></img>
</xsl:template>
</xsl:stylesheet>

In this case, the <img> tag ends up encompassing whatever is underneath it.

2) On the other hand, if I go ahead and try to do this with XHTML

<?xml version="1.0"?>
<html>
<head>

<title></title>
</head>
<body>
<img src="/members/images/header.jpg" /> ok?

</body>
</html>

Anything with a namespace of xsl (like <xsl:template>) gets removed, and
surrounding <html> tags are added, since HTML is added.

What I'm looking for / wondering with Tidy is either:

a) Can I run tidy on my xsl file in XHTML mode where it doesn't try and
create <html>, <head> and <body> tags to wrap around my code.

or

b) Can I run tidy in XML mode, and specify specific tags like IMG or BR
to auto-correct in a way that the tag gets closed immediately? So that
<br> becomes <br /> and the like, without having to treat it like HTML?

Thanks,

Tidy's XML parser and pretty printer may modify the white space in the
document in ways that you do not wish it to, that would already make it
an unsuitable tool for this task. It also does not know anything about
XSLT, so you cannot expect any context-aware processing. I would suggest
to use some other tool, perhaps libxml2's xmllint does a better job with
the recover option, I would not count on it though.

No.

Probably not.
