[Pyparsing] parsing SVG styles

[Donn I. <don...@gm...>]

Hello again,
 I have now spent almost 3 hours on this and I've also looked at the
examples and read the pdfs, but I just can't get this going. I actually
find the docs and the adventure example too complicated -- I'm a simple
sort.
 
I'll post my code and hope for mercy -- as I've been told to rtfm before :)

I'm trying to "pick-out" certain keywords (and args) from a string (style
node in an SVG file) from amidst a babble of noise and just record those
for later use.

fill:#[6 hex nums];
fill-opacity:#[float or int];
stroke:#[6 hex nums];
stoke-width:#[float or int];

This is my latest test:

# Cover [1] or [0.587]
floatOrInt = Combine(Word(nums) + Optional(Literal(".") + Word(nums)))
# Cover any amount of hex, [ab][abcf]
hexNums = Word(hexnums)
# A semi-colon seps commands
semi = Literal(";").suppress()
# hacking the commands
FILL_command = Optional("fill:#")# + Group(hexNums + semi)
FILLOPACITY_command = "fill-opacity:#" + floatOrInt + semi
STROKECOLOR_command = "stroke:#" + hexNums + semi
STROKEWIDTH_command = "stroke-width:#" + floatOrInt + semi
# Trying to sum them up. Remarked down to one for testing
stylecommand = FILL_command# | FILLOPACITY_command | STROKECOLOR_command |
STROKEWIDTH_command
# Hacked during tests, tried to simplify.
phrase2 = stylecommand#OneOrMore(Group(stylecommand))

#The test string
style="opacity:1;color:#000000;fill:#6bdc23;fill-opacity:0.4611111;fill-rule:nonzero;stroke:#ff0000;stroke-width:6;stroke-linecap:butt;stroke-linejoin:miter;marker:none;marker-start:none;marker-mid:none;marker-end:none;stroke-miterlimit:2;stroke-dasharray:none;stroke-dashoffset:0;stroke-opacity:1;visibility:visible;display:inline;overflow:visible;enable-background:accumulate"

tokensStyle = phrase2.parseString(style)
# I also tried scanString()

print tokensStyle

# Trying to get a result.
for a in tokensStyle:
    print a
##    for command in a:
##        print ":",command
