What is wrong with this reg expression?

[dimitad]

Hi all,

I cant figure out why this regular expression generates an error:

s/([0-9a-zA-Z])/"<a href=some.php?id=".process($1)."></a>"/ei )

"process($1)" is a function call but I have the "e" attribute at the end so that its evaluated correctly. The error from this is: Bareword found where operator expected at file.pl

Also if I remove the part after process($1) - it works?!?

Thanks!

The forward slash in </a> closes your regular expression. You have two options.

a) escape the forward slash by putting a backslash before it:

s/([0-9a-zA-Z])/"<a href=some.php?id=".process($1)."><\/a>"/ei

b) use a different delimiter for your regexp:

s!([0-9a-zA-Z])!"<a href=some.php?id=".process($1)."></a>"!ei
s{([0-9a-zA-Z])}{"<a href=some.php?id=".process($1)."></a>"}ei
s,([0-9a-zA-Z]),"<a href=some.php?id=".process($1)."></a>",ei
