Thanks for the suggestion! i think i have what youre looking for Tim, take a look at this script output nathan@devel ~ $ php testDom.php IN: <?xml version="1.0" standalone="yes"?> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" " http://www.w3.org/TR/REC-html40/loose.dtd";> <html><body>Test<br/><h2>quickshiftin@xxxxxxxxx<a name="bar">stuff inside the link</a>Foo</h2><p>care</p><p>yoyser</p></body></html> OUT: <?xml version="1.0" standalone="yes"?> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" " http://www.w3.org/TR/REC-html40/loose.dtd";> <html><body>Test<br/><h2><a href="mailto:quickshiftin@xxxxxxxxx";> quickshiftin@xxxxxxxxx</a><a name="bar">stuff inside the link</a>Foo</h2><p>care</p><p>yoyser</p></body></html> and heres the code using the DOM extension you may have to tweak it to suit your needs, but currently i think it does the trick ;) <?php $doc = new DOMDocument(); $doc->loadHTML('<html><body>Test<br><h2>quickshiftin@xxxxxxxxx<a name="bar">stuff inside the link</a>Foo</h2><p>care</p><p>yoyser</p></body></html>'); echo 'IN:' .
