The obvious answer seems to be "pass the DOMDocument around".  

The point of doing a DOM parse is to obtain a structure you can hold in
memory.  If the document is too large to hold in memory - DOM
representations are typically larger than the corresponding file - then
consider using SAX parsing. 

Parsing is slow, like any other I/O operation, so doing it "again and
again" should be avoided.
