how 2 preg_match dynamic input?

[kucing]

Here is my question which is bothering me!

I have dynamic data from html pages which i have to match and replace with new data

 

Which could be

 

    <table width="100%" border="0" cellpadding="0" cellspacing="0">
      <tr>
<td width="425" valign="top" align="left">test<td>
</tr>

 

or

 

    <table width="50" border="0" cellpadding="0" cellspacing="0">
      <tr>
<td width="20" align="right">test</td>
<td width="20" align="right">test</td>
</tr>

 

or

 

    <table width="500" border="0" cellpadding="0" cellspacing="0">
      <tr>
<td width="200" align="right">test<td>
</tr>

 

 

or

 

    <table width="500" border="0" cellpadding="0" cellspacing="0">
      <tr>
<td width="200" align="right">test<td>
</tr>

 

 

or

 

if ($a==1)
print_r($a);
else
print_r("test");
$a++;

 

or

 

if ($a==1){
print_r($a);
/////////example
}
else{
print_r("test");
/////////example
}
$a++;

 

Sorry for the long examples, well now I would appreciate if someone can help me with this.

Thanks

Is there anything special about these, or are you trying to capture all tables and all if statements with $a?
