( #3333=superdoc: print w/replies, xml ) Need Help??

It would be a lot more helpful if you would supply a single snippet that produced the error, rather than lots of little bits with no context.

I haven't been able to reproduce your error exactly, but at least part of the problem is that \b means something different when interpolated in a string, than when interpolated in a regex. A backspace versus word boundary.

However, the fact that when you print $regex out having interpolated it into a string, it gets printed as \b\QRenata\E\b means that the contents of $regex must originally be (something like):


And when you try to use that as a regex, the escaped (doubled) backslashes means that the regex engine will not recognise the escape sequences.

That I cannot reproduce the errors you are seeing probably means that your snippets do not reflect what you are really doing in your code, and I haven't been able to read between the lines sufficiently to guess what it is that you are actually doing.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

In the absence of evidence, opinion is indistinguishable from prejudice.

  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  • 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).
