Regular Express Help Needed Please!

[Raj.SB]

I have a reg exp pattern as below works fine for the string : <param name="url" value="contents/cf_intro.htm" valuetype="ref">

mObjRegExp.pattern="<param.+?value=""([^""]+)""

But the same is not working for

<param name="url" valuetype="ref" value="../fmmain/fmindex.htm"

note that, i want to capture the url that comes after value=". if the value=" comes in the second place in the html tag it works. but if it comes in the 3rd position, then it doesn't work.
Can anyone help me finding the problem and make it work for both?thanks in advance.

What does "not working" mean? Please show more code. I tested the
regular expression you provided and it behaves as expected.

Hi Thanks for the reply first

Not working means, the reg exp does not return the url in between the quotes after 'value=' from the following string
<param name="url" valuetype="ref" value="../fmmain/fmindex.htm"> . it works for this string
<param name="url" value="contents/cf_intro.htm" valuetype="ref">

the only difference between these two is the string i try to capture comes second in the working one, but in the not working string it comes as the third. am i explaining it clearly?

Your outer IF statement checks for the following:

InStr(lcase(strLine),"<param name=""url"" value=")

This check fails for the first strLine listed.
