[XSL-LIST Mailing List Archive Home] [By Thread] [By Date] [Recent Entries] [Reply To This Message] Mysterious appearance of xmlns="" in output
Well hopefully it's only mysterious to me...
I get extra xmlns="" attributes in different HTML tags in the output
generated by MSXML4. I've reduced the problem to the following XSLT:
---------------------------------------------------
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" encoding="UTF-8" indent="yes"/>
<!-- VERY SIMPLE ROOT TEMPLATE MAKES A SINGLE CALL TO Header-->
<xsl:template match="/">
<html xmlns="http://www.w3.org/1999/xhtml" lang="en" xml:lang="en">
<xsl:call-template name="Header"/>
</html>
</xsl:template>
<!-- HEADER TEMPLATE SIMPLY OUTPUTS A BASIC HTML Head TAGSET-->
<xsl:template name="Header">
<head>
<meta http-equiv="Content-Type" content="text/html;
charset=iso-8859-1"/>
<title>Title</title>
</head>
</xsl:template>
</xsl:stylesheet>
---------------------------------------------------
I expected the following output from the transformation:
---------------------------------------------------
<?xml version="1.0" encoding="UTF-8"?>
<html lang="en" xml:lang="en" xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type"
content="text/html;
charset=iso-8859-1" />
<title>Title</title>
</head>
</html>
---------------------------------------------------
What I get instead is a 'head' tag that looks like this:
<head xmlns="">
If I replace the <xsl:call-template name="Header"/> with the contents
from the Header template, the xmlns attribute is NOT inserted.
If I remove the xmlns="http://www.w3.org/1999/xhtml" attribute from the
<html> tagset and leave the <xsl:call-template name="Header"/>, the
xmlns attribute again is NOT inserted.
If I go back to inserting the <head> tagset with a call-template and
change the Header template to the following (I know it's invalid HTML,
but for testing purposes I don't believe that should matter):
---------------------------------------------------
<xsl:template name="Header">
<head/>
<meta http-equiv="Content-Type" content="text/html;
charset=iso-8859-1"/>
<title>Title</title>
</xsl:template>
---------------------------------------------------
I get three extra xmlns="" attributes as follows:
---------------------------------------------------
<?xml version="1.0" encoding="UTF-8"?>
<html lang="en" xml:lang="en" xmlns="http://www.w3.org/1999/xhtml">
<head xmlns="" />
<meta http-equiv="Content-Type"
content="text/html;
charset=UTF-8"
xmlns="" />
<title xmlns="">Title</title>
</html>
---------------------------------------------------
Does anyone understand this behaviour, and more importantly does anyone
know how I can turn it off without sacrificing call-templates or the
xmlns namespace definition? Actually for that matter, I'm not sure what
the xmlns namespace definition does for me. I added it when I converted
the website to XHTML just because I blindly copied from an example
somewhere. If I can sacrifice that without violating any spec, I will,
although, I'd still like to understand what's happening...
Thanks.
