<form action="track_mobile.asp" method="post" name="TrackMobile">
<table width="99%" height="55" border="0" cellpadding="2" cellspacing="0">
<tr>
<td class="Heading2" colspan="2"> Track Any Mobile Location</td>

<tr>
<td width="21" valign="top" rowspan="2" class="s2stextbox" valign="top"><img src="../images/operators_logo/Tata.png" width="134" height="121" align="left"> </td>
<td width="897" valign="top" class="s2stextbox"><font size="2"><b>Mobile Number: </b>918888888888</font></td>
</tr>
<tr>
<td width="897" valign="top" class="s2stextbox" valign="top"><font size="2"> <b>User Name:</b> We are unable to trace the Name for this Mobile Number<br>

Answer 1

1. Strip-out HTML tag
$text = strip_tags($html);
2. Match using text before column
I just change the regexp and display each value match by (.*) (everything that follow the pattern up to the end of line:
preg_match('/Mobile Number: (.*)/', $html, $matches);
echo $matches[1];
preg_match('/User Name: (.*)/', $html, $matches);
echo $matches[1];
preg_match('/Mobile Operator Name: (.*)/', $html, $matches);
echo $matches[1];
preg_match('/State/Region: (.*)/', $html, $matches);
echo $matches[1];

This is a work for XPath (see [SimpleXMLElement::xpath][1], your XPaths look like be:
918888888888
/form/table/tr[1]/td[2]/font[substring-after(./text(), ':') ->
We are unable to trace the Name for this Mobile Number
/form/table/tr[2]/td[1]/font[1][substring-after(./text(), ':')
TATA TELESERVICES
/form/table/tr[2]/td[1]/font[2][substring-before(substring-after(./text(), ':'), 'State')
Maharashtra
/form/table/tr[2]/td[1]/font[2][substring-after(./text(), 'Region')
