I try that and get complete failure (the regex doesn't match at all).

That second grouping has some odd stuff going on in there; you start a character class, but have another one embedded inside it and it looks like you're also trying to use quantifiers in there, then you have an unescaped - which attempts to specify that you're seeking to match a range between what goes before and what goes after.

So let's step back one square: what kinds of things are you trying to match?

Presented with *this* example, I'd go much simpler and do:

if ( $x=~ /([^.]+)\.(\S+)/ ) { ... }

Unless those patterns are too forgiving ...

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
