idiom for iterating

normally, you would use the keyword <fromend> to iterate over matches
in a file. this works when the pattern is simple, like
/(what-you-want)(something-else)/.

however, when you are looking for something that looks like this:
/(start-tag)(you-want-this)(next-start-tag)/, the <fromend> keyword
will cause you to only match every second instance. the <fromnext>
keyword will cause you to match every instance but the first.

therefore, i have resorted to this clumsy hack:

	match (:: :url: :text: :next-url:) [:file:] /(#http:.*?CET
....)(.*?)(#http:|$)/
	isolate (:article:) /:*:url::*:text:/
	call /:main:/ [:*:article:]
	{
 	    match <fromnext> (:: :url: :text: :next-url:) [:file:]
/(#http:.*?CET ....)(.*?)(#http:|$)/
	    isolate (:article:) /:*:url::*:text:/
	    call /:main:/ [:*:article:]
	    liaf
	}

there must be a better way than duplicating all that code, right?
