Matchtext / Regular expressions: searching multiple lines

[Ken Ray]

Guys, the matchText *will* search multiple lines, but because MC
supports PCRE not Perl's RegEx, things are a little different. For the
full skinny, go to http://www.pcre.org/man.txt. But the basic is to use
"(?s)" before your match expression, and to make it not greedy, add "?".
For example, here's a search I did recently, looking for data between
<title></title> tags in an XML document. The match below will find the
first match:

on CheckIt pXMLData
  local tTitle
  get matchText(pXMLData,"(?s)<title>(.*?)</title>",tTitle)
  if it is true then
    answer "The title is: " & tTitle
  end if
end CheckIt

Hope this helps,
