I'm having trouble getting elements to be raw. I use, for example:
d = Document.new( str, { :raw => [ 'O', 'T', 'V' ] } )
Then when I traverse the document and query Element#raw it does say
'true' for these tags, but it still appears that they have been parsed
and I can't get the raw text.
e.get_text.value
Returns the same thing as
e.text
Is there another way ones supposed to use to get at the raw text?
Thanks,
T.
Sigh, I just realized I miss understood what raw meant --it's just
relates to entity parsing. Why am I getting the feeling that there is
no way to prevent parsing of the body of an element? I pray this is not
the case, b/c it means back to the drawing board for something like the
13th time :-(. But if is the case, can anyone recommend another XML
parser then can do this?
Thanks,
T.
None that I know of. The problem is this: where do you continue from,
and how do you know if not by parsing?

Well, I just want to specify a tag and anything in that tag would be
left verbatim. That's all really. I'm tryng to find info on libxml
bindings (rather difficult to find it seems) though I have a feeling
that won't work either.
Worse comes to worse I'll wipe out old trust Tagiter and see if that
will do. Otherwise I'll have to roll my own. Just what I need More
Work!
Thanks Ari.

REXML should be pretty easy to manipulate or add functions to. Why roll your own when you can just add a new behavior?

Here's a micro xml-parser (posted via Google, so the
indentation has been removed):
# Produces array of nonmatching and matching
# substrings. The size of the array will
# always be an odd number. The first and the
# last item will always be nonmatching.
def shatter( s, re )
s.gsub( re, "\1"+'\&'+"\1" ).split("\1")
end
def get_attr( s )
h = Hash.new
while s =~ /(\w+)="([^"]*)"/
h[$1] = $2
s = $'
end
h
end
def tag_name( s )
if ( s =~ /^<(\S+)(\s|>)/ )
$1
else
nil
end
end
s = ''
$<.each_line {|x| s=s+x}
all = shatter( s, /<[^>]*>/ )
all.each {|x|
x.chomp!
if x.size > 0
print x
tname = tag_name(x)
print " | " + tname if tname
print "\n"
attr = get_attr( x )
if attr.size > 0
attr.each_pair {|key,val| puts "....#{key}-->#{val}" }
end
end
}

Thanks Zach, that's a fair idea. I did a little REXML hacking a few
years back, so maybe so....
"Sean, do you still frequent this list?" Is it reasonably feasible?

Hey Thanks! Not sure if I'll end up using since I just spent last night
wrting a general purpose stack-based parser. But I'll keep it in
reference.
Love the method name #shatter, BTW.
T.
P.S. FYI, I figured out that you can just use a "margin" character in
order to preserve indention. For example, I'm using Google Groups now
too:
: class A
: def shatter
: # ...
: end
: end
As to which character you like best, that's your call ;-).
Also, I know there is a way to set the google group to a fixed-font
mode (I manage a group and there is that option), but I don't know who
manages this group and thus would be able to set it.

Thanks; I didn't think of that.

Me too, but what you gonna do?
Also, btw, I should have mention that the small size of your parser is
impressive --micro indeed!

mall size of /your/ parser
Oops. I mean William's parser!
