[Resolved] Code for parsing some text. ( preg_replace )

PyroX

Heya,

Thought I would try this reworded, and with an attachment that shows the fromat used, etc.

So using the attached sample.txt , can anyone, using preg_replace, or preg_match, or preg_match_all , and PHP :

1) open the file, read it AS IS, do not edit the file as the format needs to be unchanged.

2) replace <textarea name=""></textarea> with <table><tr><td>NAME=</td><td>VALUE=</td></tr></table>

So when run, the textarea is converted to a table with the name and value of the textareas contained in the file.

Anyone up to this?

So far I got:

preg_replace('/<textarea(.)name="(.)"(.)>(.)<\/textarea>/is','html here',$content);

Which does not work at all for me.

So, I am iterested in how someone else might go about this, or if a regex god comes in and modifies my regex, well that would be nice too.

Maybe Weedpacket, or someone of his caliber.

Thanks in advance for the effort(s).

Dunno what you're using for "html here"; the and would be \2 and \4 to match the 2nd and 4th bracketed pieces.

One thing you'll need to do is put (.?) rather than (.), because tries to match as much of the string as possible, and you don't want that. ? matches as little of the string as possible.

Ya I just didn't want to post the whole thing, here ya go:

$file = preg_replace('/<textarea(.)name="(.)"(.)>(.)<\/textarea(.*)>/i','<input type="hidden" name="\2" value="\4"><table border=0 class="borderon" cellpadding="8"><tr><td>\4</td></tr></table>',$file);

I am about to try it with the '?' , that sounds good, I can't wait to see the outcome.

That's exactly the advice I was looking for, the ? appears to have worked for the most part.

Where is info about that available by the way?

Now part 2, obviously this does not work:

$file = preg_replace('regex here','<tr><td>'.nl2br('\4').'</td></tr></table>',$file);

Can you think of anything to get the \r\n or \n to <br> inside this as well?

Got 'a' solution, don't know how good it is, what do you think of this:

In the previous preg_replace, I added 'idx' to the TD and then once everything is replaced:

    preg_match_all('/<td\ idx>(.*?)<\/td>/is',$file,$matches);
            for($l=0;$l<count($matches[1]);$l++){
            $file=str_replace($matches[1][$l],nl2br($matches[1][$l]),$file);
            }

this matches the newly created <td idx> , gets the text, adds the <br> via str replace

I dunno, it works every time, so I am happy.

Thanks WEED!
