Re: how to extract part of HTML page

Hi everyone,

I'm trying to write a PHP script that connects to a bank's currency
convertor page using cURL and that part works fine. The issue is that I
end up with a page that includes a lot of information that I don't
need. Using the PHP function strip_tags I've ended with the text below
and from the remaining HTML code, I'd like to extract the lines starting
with "<TABLE BORDER="1" WIDTH="315">" up to its closing </TABLE> tag.
How do I do this using PHP? I tried using preg_match and the like but
my regex skills are pretty bad. Not too sure where to start. Could
someone please provide me with some pointers?

<TABLE BORDER="0" WIDTH="600">

<td width="148"></td>
<td width="448">some text some text some text some text some text</td>
</tr>
</TABLE>

<TR><TD VALIGN="top" WIDTH="148">

<TD WIDTH="448" VALIGN="top">

Thanks

Try this.

preg_match('#TABLE BORDER="1"
WIDTH="315">(.*?)?\</TABLE>#s',$source,$result);
print $result[1];

Always start small with regexes and build them up a bit at a time, if
you try and do a complex one all in one go you're asking for trouble!
