Grab chunk of HTML

[Canman2005]

Hi all

 

I have the following code

 

if ($source = file_get_contents("http://help.websiteos.com/websiteos/example_of_a_simple_html_page.htm")) {
  $search = "<h1>Example of a simple HTML page</h1>";
  $newText = substr($source,strpos($source, $search)+strlen($search), 100);
  echo $newText;
} else {
print "error";
}

 

This grabs the first 100 characters of the HTML code from an external source starting from the defined section of code.

 

Rather than grabbing the first 100 characters, is there a way to define an end tag? So it would grab everything from the start and end tags?

 

Does that make much sense?

 

Thanks very much

preg_match

 

Regular Expressions is where you want to go.

 

<?php
if ($source = file_get_contents("http://help.websiteos.com/websiteos/example_of_a_simple_html_page.htm")) {
   $search = "~<h1>(.*)</h1>~s";
   preg_match($search, $source, $match);
   echo $match[1];
} else {
   echo "error";
}

?>

either way, you'll have to read the entire file into buffer

unless you use fseek and cut some of it off.

Thank you very much

 

What would be the best way to grab the following from the external HTML

 

<table id="Table1" cellspacing="1" cellpadding="1" border="1">
  <tr>
    <td height="18" colspan="2"><a id="_ctl5_DesktopThreePanes1_ThreePanes__ctl6_LbShoppingCart" href="javascript:__doPostBack('_ctl5$DesktopThreePanes1$ThreePanes$_ctl6$LbShoppingCart','')" style="font-size:X-Small;font-weight:bold;"> View Cart</a> </td>
  </tr>
  <tr>
    <td height="18"><span id="_ctl5_DesktopThreePanes1_ThreePanes__ctl6_Label3" style="font-size:XX-Small;">Line Items</span></td>
    <td height="18"><span id="_ctl5_DesktopThreePanes1_ThreePanes__ctl6_LblTotalLineItems" style="font-size:XX-Small;">0</span></td>
  </tr>
  <tr> </tr>
  <tr>
    <td colspan="2"></td>
  </tr>
  <tr>
    <td><span id="_ctl5_DesktopThreePanes1_ThreePanes__ctl6_Label1" style="font-size:XX-Small;width:56px;">SubTotal</span></td>
    <td><span id="_ctl5_DesktopThreePanes1_ThreePanes__ctl6_LblSubTotal" style="font-size:XX-Small;">$Zero</span></td>
  </tr>
</table>
