Hi,

the \w special character is specific to perl. The equivalent in standard (extended) regex is [:alnum:]. There may be other components that are non standard. There are certainly a couple I don't recognise. regex in Tango certainly works, you just have a bit of work to do to rejig you _expression_ ;-)

Regards Simon

Subject: Witango-Talk: Question on <@REGEX ...> Does it really work?

Hello all,

I have a question regarding the metatag <@REGEX >, which I can not make it work.

In the code below, I have two identical fragments, except for the STR string.

All I am trying to do is to verify if the STR is a valid email address. The regular _expression_, EXPR, I verified to work fine in _javascript_, Perl and ASP. But I cannot figure out how it should be made to work in a taf file, and the documentation is useless.

When I run this code I always get exaclty the same result, <@VARINFO ..> reporting TEXT, and the variable local$re returns M, weather the email string is valid or not.

Any ideas?

Many thanks,
Mike.

<@! ------------------ STR = valid email address -------------------- >
<@ASSIGN NAME=local$re
        VALUE='<@REGEX EXPR="\w+([-+.]\w+)[EMAIL PROTECTED]([-.]\w+)*\.\w+([-.]\w+)*"
        STR="[EMAIL PROTECTED]"
        TYPE=B>'
>

<@VARINFO NAME=local$re ATTRIBUTE=TYPE> <@! this displays TEXT>
result = @@local$re <br>          <@! this displays M >

<@! --------------------- STR = invalid email address ---------------- >
<@ASSIGN NAME=local$re
        VALUE='<@REGEX EXPR="\w+([-+.]\w+)[EMAIL PROTECTED]([-.]\w+)*\.\w+([-.]\w+)*"
        STR="[EMAIL PROTECTED]@hotmail.com"
        TYPE=B>'
