This is basically, a SourceForge project summary page where I strip all HTML and end up with this text. I want to be able to extract as many project attributes as possible, such as: Programming Language, Translations, Developers, Activity, Topic and so on.

Now here's where the problem comes, some projects will have some attributes and other projects won't have them. For example, not all projects have the "User Interface Attribute" or the "Donors" attribute, etc... This basically makes for not being able to depend on the order in which these attributes appear in the text.

So because the order is inconsistent from a project to another I can't do something like: 

  if ( $txt =~ /Programming Language : (.*) License :/i ) {
    $result = $1;
  }

[download]

and would have to rely on something else. Is there any way to extract the pattern that matches a label and have something like: 

  if ( $txt =~ /Programming Language : (.*) $LABEL_PATTERN/i ) {
    $result = $1;
  }

[download]

? This way I can make a list of all possible labels and look for each one individually
