regex question - preg_match()

[vermaha]

Struggling with regex:
I'd like to find out if a string contains ONLY numerical characters BETWEEN tags or in some cases at the end of the string (so no closing tags). As soon as there is character data between any tags >x x x < it shouldn't be matched.

Another remark: the tags I am talking about are NOT html tags, so strip_tags() won't help me out.

A few examples:

<ps \"TblB\" 8>5 55
* that would be considered a match

<:cs "Helvetica" 2>1<:/cs>
* a match as well

<ps \"xxx\" 9>xxxxx 9830
* would not!

<ps "TblB" 27>text here<:cs "Helvetica" 2>2<:/cs>
* neither would this be a match

help much appreciated!
thnx

I would say it would be someting along the lines of

"<>([0-9])<*>"
something like that might work.... then again, regexp always apepar to get more complicated as things go on......

If I'm right, your pattern suggests that there are always two tags <xxx>0123<xxx> with digits in between, and that is not always the case. There could be spaces as well, sorry didn't mention that.

I thought of doing it the other way round: as soon as there is text (besides eventual digits) it should NOT be "found".
How can I be sure this would not be a match then - supposing I do it this way?

<blabla> 123 abc 987 def </blabla>
