problem about preg_match_all

milo_pantig

Hi There !

I used preg_match_all
e.g preg_match_all("/<tr><td>(.*)<\br>/i",$html,$matchAdd);

to get this 16x80 singlewide, 3Bdrm., 2Bath, Quiet Park, No Pets. 443-8322 but i can't get it anybody can hel me. 🙂

this are the html codes:

<tr><td>
16x80 singlewide, 3Bdrm., 2Bath, Quiet Park, No Pets. 443-8322 Alamogordo News 02/01/2005</td></tr>

<tr><td>
14 wide 2 & 3 BR, Lots also available. Specials on rent. Military welcome. Pets ok. Please call for more info. Tradewinds....437-4469. Alamogordo News 01/28/2005</td></tr>

there is a newline after the display header comment, and to a computer, and a regular expression a newline is a character, so you must include it in your pattern.

preg_match_all("/\s+<tr><td>\s+(.*?) /i",$html,$matchAdd);

also, you will want to use the greedy quantifier .*? otherwise the regex would keep capturing data until it reaches the last what the ? does is tell it to stop at the first one, rather than keep going. also there was no need for the \ in front of the b in the

Sir as you notice the <td> tag have different BGCOLOR but i need to start at <td> tag because thats the only unique identity i cant start with because theres a lot of them.how can i parse so i get the info between the html tag.

<TD ALIGN="CENTER" BGCOLOR="#DFE4EE"> 1 & 2 Bedroom Apts Includes Heat & Garage No pets. Avl 2/1. 952-934-7019</TD></TR>
<TD ALIGN="CENTER" BGCOLOR="white">1, 2, 3, 4 Br. Rentals Rent To Own Contract for Deed Below Market Below Market Properties Call Today! 952-921-8490</TD></TR>

e.g.

preg_match_all("/<TD ALIGN='CENTER' BGCOLOR='#DFE4EE'>\s+(.*?)</font/i",$html,$matchAdd);

preg_match_all("/<TD ALIGN='CENTER' BGCOLOR=''white">\s+(.*?)</font/i",$html,$matchAdd);

Thanks and More Power

try this and see how it works...


preg_match_all("/<TD [^>]+><FONT [^>]+>(.*?)<\/FONT><\/TD><\/TR>/i", $html, $matchAdd);

i think that will match either one not worrying about the td bgcolor

Cool, Cheers and More Power!

Shouldn't be using tags anyway (or bgcolor attributes) - they went out last century. Consider using stylesheets instead, and then you can name the items with something more meaningful that you can also use to search the HTML code for.

Instead of

<FONT FACE="arial">1, 2, 3, 4 Br. Rentals Rent To Own Contract for Deed Below Market Below Market Properties Call Today! 952-921-8490</FONT>

It would be

<span class="advert">1, 2, 3, 4 Br. Rentals Rent To Own Contract for Deed Below Market Below Market Properties Call Today! 952-921-8490</span>

The stylesheet would contain a declaration

.advert
{
   font-family:arial,helvetica,sans-serif; // Not everyone has Arial!
}

And the code to search for ads would be

#<span class="advert">(.*?)</span>#

You can (and should) go further and style the <td> elements themselves. Since there appear to be at least two different colours it would appear to make sense to use extra classes and mix them.

.advert
{
  font-family:arial, helvetica, sans-serif;
}
.advertrow1
{
  color: black;
  background-color:white;
}
.advertrow2
{
  color:black;
  background-color:#dfe4ee;
}

The styles would be applied to the <td> elements

<td class="advert advertrow1">1, 2, 3, 4 Br. Rentals Rent To Own Contract for Deed Below Market Below Market Properties Call Today! 952-921-8490</td>

and the expression would read

#<td class="advert advertrow.">(.*?)</td>#

<td align="left" vAlign="top" class="contents">
Single Family Homes

				</td>

i got to remove the space to get the "Single Family Homes"
how can i remove the white space pleaseeeeeeeeeee

preg_match_all('%vAlign=\"top\" class=\"contents\">(.*)<\/td>%'),$html,$match;

Weedpacket

Once you've got the match, trim() it.

Figure A ->
<td align="left" vAlign="top" class="contents">
Single Family Homes

</td>

from this example Figure A , this is the example that i can not parse or get because of the spaces ,my problem is how can i ignore the spaces because that makes my parsing not working.

drew010

after your % delimiter, try putting an s, so its like
preg_match_all('%vAlign=\"top\" class=\"contents\">(.*)<\/td>%s'),$html,$match;
