Re: Using the XML::Parser Module

[leriksen]

Another option is XML::GDOME, which, apart from a slightly outdated install process, seems to work well. And has XPath support out of the box. Again another case of the thin perl wrapper around the speedy C implementation. Doco is complete, but it doesnt hold anyones hand - if you know XML reasonably well, you should be fine - if your not familiar with the XML concepts, finding what you need can be difficult.

#!/usr/bin/perl -w

use strict;

use XML::GDOME;

my $fname = '/path/to/your.xml';

my $doc = XML::GDOME->createDocFromURI($fname,GDOME_LOAD_SUBSTITUTE_EN
+TITIES); # or whatever gdome options float your boat

my @nodes = $doc->findnodes('/xpath/to/required/element');

foreach my $node (@nodes) {
    if (needToUpdateAttribute($node)) {
        my $attributeName = getRequiredAttrName(...);
        my $newValue      = getNewAttrValue(...);

        $node->setAttribute($attributeName, $newValue);
    }
}

XML::GDOME is actually a wrapper around libgdome which is a wrapper around libxml2, so it’s no surprise that it supports the same things. libgdome adds full DOM Level 2 support on top of libxml2 (including the Events stuff and such); unless you need that (which few people probably do), you can just use XML::LibXML. The code you’ll write is identical in both cases.
