Hi,

how big is too big for an xml file to be parse by php the expat way?
is 50kb~100kb ok?

Because I'm making an expanding xml file. Not only new contents are added to the file everyday, but also when users post comments, the comments will be added to the file too.

so it is ok to parse large xml file?

thank you.

it should be ok, but it will take a while to load..you might want to post comments into another file, seperate them i suppose
