Delete all comments in an XSLT file

bonekrusher · February 25th, 2008, 11:14 AM

Hi,

I am trying to write an XSLT to delete all comments in an XSL-FO file. My file is about 25,000 lines of code. I need to delete all the verbose comments. I tried:

Code:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:fn="http://www.w3.org/2005/xpath-functions" 
exclude-result-prefixes="xs fn">
    <xsl:output method="xml" encoding="UTF-8" indent="yes"/>
    <xsl:variable name="XML1" select="/"/>
    <xsl:template match="/">
        <xsl:copy-of select="."/>
    </xsl:template>
    <xsl:template match="*">
        <xsl:copy-of select="@*"/>
    </xsl:template>
</xsl:stylesheet>

But this only returns the <fo> namespace, but not all the <xsl>.

thanks for the help.

Simply start with the identity transform, and then get the stylesheet to skip comments:

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

<xsl:template match="comment()"/>

Thanks Sam, but none of my xsl: is being returned. On the FO namespace elements.

Works fine for me. Can we see your input XML (i.e. the stylesheet you are trying to change).

Hi Sam,

keep in mind my XML input is an XSLT stylesheet that needs the comments remove.

Here is the XSLT that I need the comments removed from:

Code:

<?xml version="1.0" encoding="UTF-8"?>

<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
xmlns:fo="http://www.w3.org/1999/XSL/Format" 
xmlns:fn="http://www.w3.org/2005/xpath-functions" xmlns:xdt="http://www.w3.org/2005/xpath-datatypes"
 xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" >
    <xsl:output version="1.0" method="xhtml" encoding="UTF-8" indent="no"/>
    <xsl:variable name="XML1" select="/"/>
    <xsl:variable name="fo:layout-master-set">

        <fo:layout-master-set>
            <fo:simple-page-master master-name="default-page" page-height="11in" page-width="8.5in" margin-left="0.5in" margin-right="0.5in">
                <fo:region-before extent="0.60in"/>
                <fo:region-body margin-top="0.60in" margin-bottom="0.65in"/>
                <fo:region-after extent="0.65in"/>
            </fo:simple-page-master>
        </fo:layout-master-set>
    </xsl:variable>
    <xsl:template match="/">
        <fo:root>
            <xsl:apply-templates/>
        </fo:root>
    </xsl:template>
</xsl:stylesheet>

The following stylesheet does the job - I can only assume you have something else in your stylesheet:

Code:

<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="node()|@*">
   <xsl:copy>
   <xsl:apply-templates select="@*"/>
   <xsl:apply-templates/>
   </xsl:copy>
 </xsl:template>
<xsl:template match="comment()"/>
</xsl:stylesheet>

If that still doesn't work then what XSLT processor are you using?

Thanks Sam. I was using XMLspy's processor. I ran it through Saxon 9 and it works fine.

Thanks for the help!
