Regex Help to Strip Some Text

[vunet.us]

Please, help me with regular expression to grab image source in any
text string using the code below. I only need the regex to be plugged
in:

var strText = "some text <img src='image.jpg'and some text";

var separateBy = ", ";
var result = ""; // if no match, use this
var allMatches = strText.match(........--->reg exp<---........);
if (allMatches) {
result = "";
for (var i = 0; i < allMatches.length; i++) {
if (i != 0) result += separateBy;
result += allMatches[i];
}
}
alert(result)

Result should be: image.jpg
Thanks

What did you try for a RegExp?

(Does anyone here like constructing RegExps?)

Peter

what would you recommend: changing group or using another method?

var strText = "some text <img src='image.jpg'and some text";
Result = strText.replace(/.*/,'image.jpg');

This works as requested

Perhaps this will appeal to you:

var strText = "some text <img src='image.jpg'and some text";
strText =
strText.replace(/(some text <img src=')|('and some text)/g,'');

Or even:

var strText = "some text <img src='image.jpg'and some text";
strText =
strText.replace(/(.*?<img src=')|('>.*)/g,'');

I gotta say, after reading "Mastering Regular Expressions" (okay, just part
of it) and using RegEx Buddy (yes, I paid for it), I kind of like making
them now. The software (RegEx Buddy) is fan-freaking-tastic.

Still doesn't mean I will do the OP's homework if he doesn't even attempt
to try!
