Selective validation or "validation from a standpoint"...

#1 July 20th, 2005, 08:47 AM

Hi,

I searched for something like this, but could not locate any
information. I may have used bad keywords, or it does not make any
sense...

Anyhow, there it goes...

Let's say you overlay an XML document with markup of another
namespace, how would you tell a validating parser to ignore elements
of that other namespace?

Example:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>
Title
</title>
</head>
<body>
<h1>
<another-namespace:insert id="0"/>
</h1>
</body>
</html>

Is there any kind of validating parser that could ignore the
"another-namespace"-specific markup and simply tell me whether this
XHTML document is valid?

Regards,

Laurent

With DTDs that is not possible, you need to declare them, etc.

You could use a different schema language or you could strip anything
off the document that is not XHTML, a few lines in XSLT.

Those few lines could be:

<?xml version="1.0" ?>
<xsl:stylesheet
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="1.0">
<xsl:output method="xml" indent="yes"/>
<xsl:template match="*">
<xsl:copy><xsl:apply-templates select="@*"/><xsl:apply-templates/></xsl:copy>
</xsl:template>

<xsl:template match="@*">
<xsl:attribute name="{local-name()}"><xsl:value-of select="."/></xsl:attribute>
</xsl:template>

<xsl:template match="*[namespace-uri() !='' and namespace-uri() != namespace-uri(/*)] "/>
<xsl:template match="@*[namespace-uri() !='' and namespace-uri() != namespace-uri(/*)] "/>
</xsl:stylesheet>
