regular expression

[Luciano Tolomei]

i have to match some content in an html file.

the file is a single line.

i have to get some cell content from it.

i have build an expression but it match a lot of <tr></tr> together instead of matching on a time...

the line is more complex (with rowspan... ) and i have to retrieve a lot of cell's and there are a lot of rows.

but here a simplified example:

<tr><td><font color=\"#EFAD00\">xxxx</font></td></tr><tr><td><font color=\"#EFAD00\">yyyy</font></td></tr>

<tr>(.*)<font color=\"#EFAD00\">([^<]*)(.*)</tr>

it match yyyy, i need to match xxxx and yyyy.

i think that i have to change (.*) to make it match everything but not the </tr>
but i do not know how to do it.

So put this in your subject. A regexp might not be the answer.

Look at File::Slurp to read the file in one go.

I think you have to have a peek at HTML::TreeBuilder

see:
http://johnbokma.com/perl/froogle-script.html
http://johnbokma.com/perl/phpbb-remote-backup.html

for examples.

It seems you want to strip all the HTML tags from your data. Once you
were doing that with your example above the string "xxxx yyyy" remains.

Have a look for HTML::Strip on CPAN. This module is for stripping all
the HTML stuff. Afterwards you could try to split() your data as usual.

That is not the Right Tool for your job.

You should use a module that understands HTML for processing HTML data.

i have to get some cell content from it.

the line is more complex (with rowspan... ) and i have to retrieve
a lot of cell's and there are a lot of rows.

There is a module that can handle that for you, no need to
reinvent that wheel.

i think that i have to change (.*) to make it match everything

I think you have to change to:

use HTML::TableExtract;

Have a look at (.*?) instead of (.*). Bu as others already noted, regexps
are not the best way to tackle this.
