I want to iterate through html code and replace all references to hrefs of OFFSITE code with a "target", while keeping other hrefs (that remain within the site) alone. So, consider these two html snippets: 

    <a href="http://www.foobar.com/xxx">
    <a href="http://www.danheller.com/xxx">

[download]

I want to rewrite this text accordingly: 

    <a href="http://www.foobar.com/xxx" target="_blank">
    <a href="http://www.danheller.com/xxx">

[download]

I tried using something like this: 

while ($body_str =~ s|href="http://(.*)"|
    ($1 =~ /^www.danheller.com/) ? $1 :
    qq($1" target="_blank)|eg) {
            print "Found '$1'\n";
        }

[download]

Needless to say, it doesn't work. I keep running into a circular dependency on matching the code and then losing my place in the text for a replacement, or replacing more occurances than intended. just how far off am I? :|

In reply to replacing chunks of text only if another chunk matches a pattern by argv
