I'm looking at the PHP xml processing instructions.
I'm hosting at lycos, so using PHP4.1 with dom enabled.
I have downloaded (and uploaded!) the 'recipe' example from phpbuilder
article.
However, I cannot get any ->content to display.
I've left myself with just the barest of test apps. Cannot get it working.
A web trawl indicates that I'm doing the right thing (or I'm just totally
misunderstanding this whole process).
Any help appreciated, code follows;
The 'error' is that the ->content always returns an empty string....
