Function Documentation

int xml_next_tag	(	const char *	in,
		const char **	out,
		const char **	out_tagname,
		const char **	end
	)

Advance to next tag.

Parameters

in	Input
out	OUT: start of tag just after '<'
out_tagname	OUT: start of name of tag, skipping namespace
end	OUT: one after tag

Returns

0 on success, 1 on failure

A tag has form: <left angle="" bracket>=""><...><right angle="" bracket>=""> Within the angle brackets, there is an optional leading forward slash (which makes the tag an ending tag), then an optional leading label (followed by colon) and then the tag name itself.

Note that angle brackets present in the original data must have been encoded as < and > so they will not trouble us.
