Top Forums Shell Programming and Scripting Help using SED to comment XML elements Post 302322369 by fpmurphy on Wednesday 3rd of June 2009 01:42:03 PM

Sorry but sed or awk are not appropriate tools for massaging XML data (documents) except for very simple files. Instead you need to transform the document using a XSLT stylesheet processor.

BTW Translation_Type is an element and not an attribute. Assuming that your document is valid and well-formed, here is a stylesheet which will do the transformation that you want.

The only change I made was to add a top-level node called "root" for well-formedness. You should change "root" to the name of your top-level element.

Here is the stylesheet:
Code:
<?xml version="1.0" encoding="UTF8" ?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">

    <xsl:template match="node()">
        <xsl:if test="./Translation_Type != '9'" >
            <xsl:copy-of select="."/>
        </xsl:if>
        <xsl:if test="./Translation_Type = '9'" >
           <xsl:text disable-output-escaping="yes">&lt;!-- </xsl:text>
           <xsl:copy-of select="." />
           <xsl:text disable-output-escaping="yes"> --></xsl:text>
        </xsl:if>
        <xsl:text>&#xa;</xsl:text>
    </xsl:template>

    <xsl:template match="root">
       <xsl:element name="{ name() }" >
           <xsl:text>&#xa;</xsl:text>
           <xsl:apply-templates select="*"/>
       </xsl:element>
    </xsl:template>

</xsl:stylesheet>

Note you may have to change the encoding to suit your data set.

Assuming your document is called test.xml and your stylesheet is called test.xsl, invoking xsltproc test.xsl test.xsl gives the following output:
Code:
<?xml version="1.0"?>
<root>
<analysisMessages.js>
        <Source_Eng_Old/>
        <Source_Eng_New>Time Graph Base Properties - Analyze activities relative to time.</Source_Eng_New>
        <Source_Trans_Old/>
        <Target_Trans_New>Time Graph Base Properties - Analyze activities relative to time.</Target_Trans_New>
        <NumOfKeys>1</NumOfKeys>
        <Translation_Type>1</Translation_Type>
        <ResourceId>timeGraph???common_props_title</ResourceId>
</analysisMessages.js>
<ganttChartMessages.js>
        <Source_Eng_Old/>
        <Source_Eng_New>Show</Source_Eng_New>
        <Source_Trans_Old/>
        <Target_Trans_New>Show</Target_Trans_New>
        <NumOfKeys>1</NumOfKeys>
        <Translation_Type>1</Translation_Type>
        <ResourceId>drawGanttChartButtonCaption</ResourceId>
</ganttChartMessages.js>
<!-- <peMessages.js>
        <Source_Eng_Old/>
        <Source_Eng_New>Rerun the selected job</Source_Eng_New>
        <Source_Trans_Old/>
        <Target_Trans_New>Rerun the selected job</Target_Trans_New>
        <NumOfKeys>1</NumOfKeys>
        <Translation_Type>9</Translation_Type>
        <ResourceId>jobGrid???tooltip???RERUN</ResourceId>
</peMessages.js> -->
</root>

Note there are some question marks in the output elements. That is because I did not bother setting up the correct locale and code-set on my system to suit your sample data.

XML::Handler::CanonXMLWriter(3) 			User Contributed Perl Documentation			   XML::Handler::CanonXMLWriter(3)

NAME
XML::Handler::CanonXMLWriter - output XML in canonical XML format SYNOPSIS
use XML::Handler::CanonXMLWriter; $writer = XML::Handler::CanonXMLWriter OPTIONS; $parser->parse(Handler => $writer); DESCRIPTION
"XML::Handler::CanonXMLWriter" is a PerlSAX handler that will return a string or write a stream of canonical XML for an XML instance and it's content. "XML::Handler::CanonXMLWriter" objects hold the options used for writing the XML objects. Options can be supplied when the the object is created, $writer = new XML::Handler::CanonXMLWriter PrintComments => 1; or modified at any time before calling the parser's `"parse()"' method: $writer->{PrintComments} = 0; OPTIONS
IOHandle IOHandle contains a handle for writing the canonical XML to. If an IOHandle is not provided, the canonical XML string will be returned from `"parse()"'. PrintComments By default comments are not written to the output. Setting comment to a true value will include comments in the output. AUTHOR
