Regex delimiter

[frodo baggins]

hello everybody

this is my first experience with runrev and so far it has been kinda like a roller coaster ride, one moment i'm awestruck , the next moment i'm almost scratching my head uncontrollably.

anyway what is the regex delimiter?

i have this regex matchtext("<h1 ="(.*?)">" ,matchedtext) and i tried \ as the delimiter but i got an error

i'd appreciate help in this

pardon my grammar, i'm in a bit of a hurry.

I know what you mean, Frodo. Many things are amazingly easy then something seemingly simply is confounding.

You're using the correct literal character, "\". This works for me.

Code: Select all

on mouseUp
   put "<a href=" & quote & "http://forums.runrev.com" & quote & ">RunRev Forum</a>" into tUrl
   get matchText ( tUrl, "<a href=\"(.*?)\">", tMatchedText)
   put tMatchedText
end mouseUp

This displays

Thanks a lot dablock, your code worked.

i had not added the command 'Get' before matchtext and hence the error

just one last question,

is there a way to get all the matches of a pattern into an array or something and then iterate over the them and print it?

I tried doing so but the variable got only the first match!

Also, Is there some sort of foreign function interface to c/c++ or some other language in runrev? I'm thinking of creating a pcre compatible regex package with named captures and all that if there is an ffi interface. The present regex library falls short on many counts in my opinion.

There *is* an externals api, but it's about to get a major revision, so you'd probably want to wait until after the conference to get started on this.
