Re: RX.Tool ? span multiple lines:
to preserve my sanity, I don't want to look too deeply into this
'can of worms', but to delete the text-stretches between "<"
and ">" -- possibly spanning several lines; is this algorithm usable ?
1. assume/hope that consecutive lines to be deleted can be appended
into one big line without problems.
2. lines which will need modifying will be formatted thus:-
A.
<possibly-empty-string1> "<" <string> ">" <possibly-empty-string2>
modified to
<possibly-empty-string1> <possibly-empty-string2>
B.
<possibly-empty-string1> "<" <possibly-empty-string2>
modified to remove the line terminator.
It seems to me that by repeatedly applying transformations A, B;
the text would be transformed as required; i.e. delete the "<,>" and
all enclosed text ? Does this work with newer versions of RX.* ?
