My apologies if my original example wasn't very clear. Here's some sample data pulled from the XML files:

Code:
<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>


I'm looking specifically at the <Translation_Type> attribute, and deciding whether to comment the entire element or not based upon what that integer is.

In the sample above, I'd want the last element to be commented out in this format:

Code:
<!--<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>-->

I'm familiar with PHP, but I've only done a little XML parsing with it before. I was under the impression that while I could parse through the XML and easily match/do logic on the Translation_Type values, I wouldn't be able to drop in those comments before and after the element? I'll certainly go back and look through my notes, but I was remembering using a multi-dimensional array type data structure to access the various elements, not actually editing the raw line-by-line file itself (that part being hidden via the PHP class, obviously you can add/drop/change the XML attributes).

XML::Grove::AsCanonXML(3pm)				User Contributed Perl Documentation			       XML::Grove::AsCanonXML(3pm)

NAME

       XML::Grove::AsCanonXML - output XML objects in canonical XML

SYNOPSIS

	use XML::Grove::AsCanonXML;

	# Using as_canon_xml method on XML::Grove objects:
	$string = $xml_object->as_canon_xml( OPTIONS );

	# Using an XML::Grove::AsCanonXML instance:
	$writer = XML::Grove::AsCanonXML->new( OPTIONS );

	$string = $writer->as_canon_xml($xml_object);
	$writer->as_canon_xml($xml_object, $file_handle);

DESCRIPTION

       "XML::Grove::AsCanonXML" will return a string or write a stream of canonical XML for an XML object and it's content (if any).

       "XML::Grove::AsCanonXML" objects hold the options used for writing the XML objects.  Options can be supplied when the the object is
       created,

	   $writer = XML::Grove::AsCanonXML->new( Comments => 1 );

OPTIONS

       Comments
	   By default comments are not written to the output.  Setting comment to TRUE will include comments in the output.
