Using Javascript regular expression for filtering HTML

Question

Good morning

is there a clever way to use a javascript regular expression to clean up this string:

var spans = "<SPAN><A href="javascript:sel.RemoveProductFromSelection('12372');"><IMG src="remove.gif" width=18> </A>Mirage - JOY</SPAN>
<SPAN><A href="javascript:sel.RemoveProductFromSelection('12427');"><IMG src="remove.gif" width=18> </A>Nikon - D40 </SPAN>
<SPAN><A href="javascript:sel.RemoveProductFromSelection('12438');"><IMG src="remove.gif" width=18> </A>Mitsuca - DS 6083 </SPAN>"

and produce a resulting array like this:

var filtered = ["12372","12427","12438"];

the source html string in spans variable could be indented or not.

thanks in advance

Is the string initially part of the document? It would probably be easier to extract the values while they are still in the DOM. — andrewmu

I'd suggest matching just the script portion. Something like this:

regex = /RemoveProductFromSelection\('(\d+)'\)/g;

while (match = regex.exec(spans)) {
   console.dir(match);
}

note: I've used console.dir() here to output the results in an easy to read format. console.dir() is a debugging function in Firebug; if you're not using Firebug, you'll need to use a different method to see the results.

Hey Spudley, here is what I've got so far

var filtered= spans.match(/\('(\d+)'\)/g);
for (var k=0;k<filtered.length;k++){
   filtered[k] = filtered[k].match(/\d+/g);
   alert(filtered[k]);
}
