preg_match_all, and whitespace

[MasterEvilAce]

How do I make this code work no matter how much space is inbetween the html tags?$template = '<table cellspacing="0" cellpadding="0" border="0" width="100%"><tr><td><h1>(.*)</h1></td><td align="right">&nbsp;</td></tr></table>';
preg_match_all("|".$template."|U", $copy, $system);Doesn't work if the text appears like<table cellspacing="0" cellpadding="0" border="0" width="100%">
<tr>
<td><h1>BLAH HAHA!</h1></td>
<td align="right">&nbsp;</td>
</tr>
</table>

I'd like to keep the PHP on a single line, just so it takes up less space

Did you try using the 'x' modifier? I believe that ignores all whitespace.

[MasterEvilAce]

:/

tried it, but it doesn't change anything

Then you'll have to change the template. I think \w matches a whitespace, so put \w* everywhere where there might be whitespace. And that's a lot of places ;)

It's not pretty.

ok, got the problem figured out and all...


but.. using preg_match_All, it's weird..

$img[1][1]
$img[1][2]
$img[1][3]

Grabs correctly, but it SKIPS the first instance of the found string..
(Say i'm looking for the word "Hi", I only need that word 3 times.. but there are only 3 instances of the word, in the text.

The FIRST two variables will be "Hi".. the third will be EMPTY. It's skipping the first instance of the string to be found..


if I do:
$img[1][0]
$img[1][1]
$img[1][2]
The LAST two are "Hi".. but the first one is a WHOLE LOT more text than I specified to search for.. but the second variable *IS* the second instance of "Hi" and the third IS the THIRD instance of "Hi"

So.. something is really weird.. and I have no idea what's wrong with it.... Any suggestions?

BTW: I'm using non-greedy statements (matches as little text as possible)

[MasterEvilAce]

when i do
$img[1][0]

it seems to be grabbing TOO MUCH.
but I have the greediness OFF... but it's still grabbing too much

i don't understand.. in my expression, are there any non-literal characters that i forgot to escape?

[CornedBee]

Arrays start with 0. But for regexp matches, [0] is the whole input string. What about $img[0][n] ?

[MasterEvilAce]

$img[1][0] -- Too much.. or whatever..
$img[1][1] -- Is actually the SECOND image on the page
$img[1][2] -- Is the THIRD image on the page

[CornedBee]

You sure your expression captures the first image?

To keep a string on a single line use this...


Function sameLine($string)
{
$string = str_replace("\n","",str_replace("\r","",$string));
return $string;
}

yes, most definitely, it does...

All the images are setup the same, on the pages i'm grabbing the html from...

I use something similar, and so yes, everything is on a single line, but the code still seems to capture too much, the first time..
