Unfortunately the PHP DOM classes and functions are not very well documented and I am starting projects that are going to be very XML heavy. I do not have a solid grasp on the DOM functionality and have been making due with SimpleXML abd XMLWriter untill now, but I am running into some serious problems with their limitations.
Is there a good book with lots of cookbook examples that teach you the ins an outs of the PHP DOM? A lot of what I am doing is translating some constrained syntax xml into verbose xml, converting non xml data sources to xml, and converting xml data into non xml data outputs, and the tutorials I have available are not all that enlightening.
