Yep. > 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; Make this: <meta xmlns="http://www.w3.org/1999/xhtml" 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?

You could also add the declaration to the stylesheet element (then you wouldn't have to repeat it). XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
