Words inside xml tags

[kaptlid]

I was given some non validating huge xml files to work with.
I need to print the words enclosed between certain tags.

Example: There are 25 instances of words inside <def> </def> tags in an xml file.

How do I output only the 25 words in between the tags?

The xml files are on average 3MB each in size.
And does anyone know a good website that explains regular expressions to a person who's never coded them?

Thanks,

website on regular expressions: regular-expressions.info

code

$pattern = '/<def>(.*?)<\/def>/ims';
preg_match_all($pattern, $xmlContent, $matches);
echo '<pre>';
print_r($matches);

the matches are contained in $matches[1] ... [n]
