You need to query by namespace as well as tagname. There is the getElementsByTagnameNS method for that: http://www.php.net/manual/en/domdocument.getelementsbytagnamens.php

That <prefix:name> syntax is shorthand for writing <my-namespace:name>, so you would query by the namespace that is bound to the p or p1 prefix. E.g. if p is declared like this: xmlns:p="test" it means that to query for p:price is equivalent to query for price elements in the "test" namespace. So in that case you'd supply the "test" namespace. In other words: ignore the "p" prefix, use its namespace directly.
