Hi
I am working on a webproxy portlet which fetches the contents of a web page and displays it in a portlet.
while doing so this portlet creates proxy of all the links. This is done with the help of an XSL.

Here is the XSL contents:

<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version="1.0"
   xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
   xmlns:bridge="java:org.portletbridge.portlet.BridgeFunctions"
   extension-element-prefixes="bridge">

<xsl:output method="html"
      encoding="UTF-8"
      indent="yes"
      standalone="no"
      omit-xml-declaration="yes"/>

<xsl:param name="bridge"/>
   <xsl:variable name="base" select="/HTML/HEAD/BASE/@href"/>

<xsl:template match="/HTML">
      <xsl:apply-templates select="HEAD"/>
      <xsl:apply-templates select="BODY"/>
   </xsl:template>

<xsl:template match="/HTML/HEAD">
      <xsl:apply-templates select="STYLE"/>
      <xsl:apply-templates select="LINK[bridge:equalsIgnoreCase($bridge, @rel, 'stylesheet') and (not(@media) or (@media != 'print' and @media != 'handheld'))]"/>
      <xsl:apply-templates select="SCRIPT"/>
      <xsl:apply-templates select="TITLE"/>
   </xsl:template>

<xsl:template match="/HTML/HEAD/TITLE">
      <xsl:value-of select="bridge:setTitle($bridge, text())"/>
   </xsl:template>

<xsl:template match="/HTML/BODY">
      <DIV>
	      <xsl:attribute name="class">
	         <xsl:value-of select="@class"/>
	      </xsl:attribute>
	      <SCRIPT>
	          <xsl:value-of select="@onload"/>
	      </SCRIPT>
	      <xsl:apply-templates select="node()"/>
      </DIV>
   </xsl:template>

<xsl:template match="A/@href">
      <xsl:attribute name="href">
         <xsl:value-of select="bridge:link($bridge, $base, .)"/>
      </xsl:attribute>
   </xsl:template>

<xsl:template match="A/@onclick">
      <xsl:attribute name="onclick">
         <xsl:value-of select="bridge:script($bridge, $base, .)"/>
      </xsl:attribute>
   </xsl:template>

<xsl:template match="SCRIPT/@src">
      <xsl:attribute name="src">
         <xsl:value-of select="bridge:link($bridge, $base, .)"/>
      </xsl:attribute>
   </xsl:template>

<xsl:template match="IMG/@src">
      <xsl:attribute name="src">
         <xsl:value-of select="bridge:link($bridge, $base, .)"/>
      </xsl:attribute>
   </xsl:template>

<xsl:template match="INPUT/@src">
      <xsl:attribute name="src">
         <xsl:value-of select="bridge:link($bridge, $base, .)"/>
      </xsl:attribute>
   </xsl:template>

<xsl:template match="MAP/AREA/@href">
      <xsl:attribute name="href">
         <xsl:value-of select="bridge:link($bridge, $base, .)"/>
      </xsl:attribute>
   </xsl:template>

<xsl:template match="/HTML/HEAD/STYLE">
      <xsl:copy>
         <xsl:apply-templates select="@*"/>
         <xsl:value-of select="bridge:style($bridge, $base, .)"/>
      </xsl:copy>
   </xsl:template>
   
   <xsl:template match="@style">
      <xsl:attribute name="style">
         <xsl:value-of select="bridge:style($bridge, $base, .)"/>
      </xsl:attribute>
   </xsl:template>

<xsl:template match="/HTML/HEAD/SCRIPT[@src]">
      <xsl:copy>
         <xsl:apply-templates select="@*"/>
         <xsl:attribute name="src">
            <xsl:value-of select="bridge:link($bridge, $base, @src)"/>
         </xsl:attribute>
      </xsl:copy>
   </xsl:template>

<xsl:template match="/HTML/HEAD/SCRIPT/text()">
      <xsl:value-of select="bridge:script($bridge, $base, .)"/>
   </xsl:template>

<xsl:template match="/HTML/HEAD/LINK">
      <STYLE type="text/css">@import "<xsl:value-of select="bridge:link($bridge, $base, @href)"/>";</STYLE>
   </xsl:template>

<xsl:template match="FORM/@action">
      <xsl:attribute name="action">
         <xsl:value-of select="bridge:link($bridge, $base, .)"/>
      </xsl:attribute>
   </xsl:template>

<xsl:template match="@*|*">
      <xsl:copy>
         <xsl:apply-templates select="@*|node()"/>
      </xsl:copy>
   </xsl:template>
</xsl:stylesheet>

My problem is that if the page that is being accessed using this portlet contains html tag with xmlns then it does not get properly parsed
but if it just has <html> tag then it works properly.

Here is the example:
----------------------------------------
HTML Source:

Since the source has HTML with xmlns <HTML xmlns="http://www.w3.org/1999/xhtml">

The output to the portlet remains same as the original html (which is wrong).
If the source htlm doesn't have xmlns then following is the output for the portlet. (This is desired)

Please suggest me what needs to be changed in XSL to fix this problem.

HTML source:

<HTML xmlns="http://www.w3.org/1999/xhtml">

You should qualify the xsl template to use the namespace:

If you want the template to match against a HTML element which doesn't have a namespace then you could add a "|" (or) condition:
