it should still fix some issue I have requirement to validate timezone format. I am getting timezone in string format like the following way.
code :
^-?\d{1,2}(?:\.\d{1,2})?$
^(?:-?(?:1[01]|[0-9])(?:\.\d{1,2})?|12)$

With these it helps After reading RFC 3986, I have to say I was wrong. That regexp is fully working (that I know). First mistake I had was syntax of IPv6 addresesses, they are put around [], and second was about example.org: (note trailing double dot :). But as the RFC says scheme can have dots in it, so it's also valid.
So that's valid RFC way to do it, but people will usually (as I will) need to modify it to only accept some schemas.

Any of those help It's not possible to validate XML with regular expressions. XML is not a regular language.
Use an XML parser to try to parse the string as XML or else validate the XML document against a schema, for example a DTD or XSD file.

wish helps you How do you check, in JavaScript, if a string is a proper regular expression that will compile? , You can use try/catch and the RegExp constructor:
code :
var isValid = true;
try {
    new RegExp("the_regex_to_test_goes_here");
} catch(e) {
    isValid = false;
}

if(!isValid) alert("Invalid regular expression");

I think the issue was by ths following , I wrote my URL (actually IRI, internationalized) pattern to comply with RFC 3987 (http://www.faqs.org/rfcs/rfc3987.html). These are in PCRE syntax.
For absolute IRIs (internationalized):

I hope this helps . This sounds like a bad idea: The language of valid XHTML strings is not regular.
Use an HTML parsing library instead. A few examples:
