[RESOLVED] help with RegExp

[chulimanga]

Hi,
could you help me to find the right RegExp to solve my problem? In htmlText are images and I need to assign them unique ID

original:

<img src="/imgs/image001.jpg" width="150" height="100" /> text text text text text text text text 
<img src="/imgs/image002.jpg" width="180" height="100" /> text text text text text text text text 
<img src="/imgs/image006.jpg" width="170" height="100" /> text text text text text text text text 
<img src="/imgs/image005.jpg" width="160" height="100" /> text text text text text text text text 
<img src="/imgs/image022.jpg" width="140" height="100" id="myid"/> text text text text text text text text 
<img src="/imgs/image109.jpg" width="110" height="100" /> text text text text text text text text

converted:

<img src="/imgs/image001.jpg" width="150" height="100" id="pic1"/> text text text text text text text text 
<img src="/imgs/image002.jpg" width="180" height="100" id="pic2"/> text text text text text text text text 
<img src="/imgs/image006.jpg" width="170" height="100" id="pic3"/> text text text text text text text text 
<img src="/imgs/image005.jpg" width="160" height="100" id="pic4"/> text text text text text text text text 
<img src="/imgs/image022.jpg" width="140" height="100" id="pic5"/> text text text text text text text text 
<img src="/imgs/image109.jpg" width="110" height="100" id="pic6"/> text text text text text text text text

Thanks!

you can't do it with just regexp - you need a little logic.

also, i see one line in the original already has an id - not sure if that's supposed to be there or not - i presumed it might, so accounted for it.

this works, but is a little hacky:

var n:int = 1;
var converted:String = original.replace(/id=\"(\w+)\"/gm, '').replace(/\s+?\/>/gm, function(a,b,c):String{
    return " id=\"pic" + (n++) + "\"" + a;
}); 

personally, instead of regexp, i'd turn that into xml, then set the "id" attribute, then output the new XML as a string, like so:

var xml:XML = new XML('<root>' + original + '</root>');
var l:int = xml.img.length();
for (var i:int=0; i<l; i++) {
    xml.img[i].@id = "pic" + i;
}
trace(xml); 

if those text nodes weren't floating around, you could do something a little more elegant using childIndex, possibly using straight E4X assignment, but that's probably not likely if you're pulling from text

moagrius,
that's nice one! Turning that to XML is a perfect solution!

Thanks a lot!
