HTML::TokeParser Problem

sirius98 has asked for the wisdom of the Perl Monks concerning the following question:

Hi, this is my code that im having a problem with:

while (my $tokenCar=$parserCar->get_tag("input")){

if ($tokenCar->[1]{name}=~/stradtext/i && $check==1) {
my $addtext = ($tokenCar->[1]{value});
...
[download]

Im Parsing an input tag that looks like this

value="some text with a 16" wheel text"
[download]

The problem is then obvious when i get to 16" the variable
$addtext gets truncated. I was wondering how i can avoid this?

It's not valid HTML to nest a double quote within a value (if the value is delimiter is a double quote). ie. This isn't HTML::TokeParer's problem. The double quote in your string should be encoded as """ ie: `value="some text with a 16" wheel text"` [download]	[reply] [d/l]

I think this is where one is supposed to use a '%HH' expression to safely invoke/evoke the "special" character (double quote in this case) without screwing up everything else: `... saloon.18%22 alloy...` [download] The same might apply to the apostrophe that occurs later in the same string (replace it with "%27"), and since you'll be doing stuff in perl with this string, you'd better treat the dollar sign as well ("%24"). By any chance, has something already been done to this text, in terms of "decoding" uri escapes, before you get to the point in your script that throws the error? If so, maybe just postpone doing that sort of step until later in the script. Update (oops): As tye points out in the following reply, I'm wrong -- it's not a URI-escape thing, it's an HTML Entity thing. So, my question should have been phrased "has something been done to decode HTML entity references (like `"`)?" If so, don't do that, or do it later.	[reply] [d/l] [select]

Sounds like you're trying to parse invalid HTML. You'll probably need to fix your input data. Where are you getting it from? -- <http://www.dave.org.uk> "The first rule of Perl club is you do not talk about Perl club." -- Chip Salzenberg	[reply]
