preg_replace to add or edit tag attribute

adrianbj

I need to either replace an existing tag attribute, or add it if it doesn't exist.

For example if preg_replace finds:

then it needs to add:

fill="#231F20"

as a new attribute, but if it finds:

then it needs to simply replace:

fill="#000000"

with:

fill="#231F20"

Keep in mind that it will come across other fill attributes (in other polygon tags) set to other colors that must be ignored, so I can't simply use remove them all and then add in just the replacement fill tag.

Thanks

Ditch preg in favor of dom

$polies = $dom->getElementsByTagName('polygon');
forech() {
	if($poly->hasAttribute('fill'))
}

Thanks so much - I didn't think of that for some reason - has made it very easy.
