finding a specific area from page using regular expression

hi friends,
i have a bunch of html pages and i want to fetch records from them and
i m really confused how i can do after working with regular
expressions and other stuffs from last few days can anyone help me
with this ?

i have a pages with html and table all scatter there..now i want just
specific table from the page and all records in that page, i was
successfull somehow but still have problems ,here are they..

my example page...(just a table it has all the tags like html but i
didnt write here just the thing i want is here)

<table>
<tr>
<img src=..">
</tr>
<tr>
<table>
<tr>
<tr>
<td>
<b>name1</B>
<br>
<font size=2 color=darkgray ><i>address1</i></font><br>
<br>phone no
| <a href=mailto:mail@gmail.com>E-mail1 </a>
| <a href='www.website.com' target=_blank>website1</a>
</font>
</td>
</tr>
</tr>
<tr>
<b> name2</b>
.........
</tr>
</table>
</tr>
</table>

now from that table i want name,address,phone no,email,website..
using preg_replace function i was able to find all those things but it
removes <A> tag so email and website are also removed...can anyone
tell me how i can find email and website first from that code and then
using preg_replace i can get other records...or else can anyone tell
me any better solution like currently by using while loop and using if
condition i m breaking at the main table and then fetching each record
but any better solution ?

As long as your HTML is "well formed", you can use the DOM functions to
process it.

Use the XPath functionality of the DOM Functions to extract the tags
you need.

This should do what you want (retrieving the email and URL):

$matches = array();

preg_match('/<a href=[\'"]?mailto:([^>\'"\s]+).*<a href=[\'"]?([^>
\'"\s]+)/s',$yourPageContents,$matches);

print "email: $matches[1], url: $matches[2]";
