One trick is, to find something that is equal between the two strings, and
work from there ...
REBOL []
myText: {<A HREF="#section1"><IMG SRC="foobar.gif"><A HREF="#section2">}
parse/all myText [
any [
to "=" here: (there: at here -4) :there [
[ "HREF=" | " SRC=" ]
copy target to ">" (print target) |
thru "="
]
]
] ; parse
In this example I used the "=" which is common to both strings, checked
whether what I have _before_ this sign is one of the two strings I'm
interested in, and then start to copy, or just go thru the "=" to start
again ...
I hope that helps,
Ingo
