Ack! I was hoping I could manipulate the incoming stuff with more of an
"out of <body>" experience.
oMyDiv = document.createElement('div'); // this div isn't attached to the
dom
oMyDiv.innerHTML = request.responseText ; // Stuff the external page URL
into this DIV
// hocus pocus...
$('target').innerHTML = oMyDiv.getElementByID('source').innerHTML ; // in
your dreams
My understanding is that until the incoming 'source' HTML is attached to the
DOM, it stays as HTML and isn't OO. If this is right, then yes, I'd need a
regEx.
I'm off to the regEx forum for assistance. This problem is what regEx was
created for. Anyone have a regEx to pull the content of element 'source'
out of a page?
Thomas - thanks for your comments. I'm stuck reading html from a
non-scripting server, so I've got to do this the hard way, but thanks.
