Recursive search in HTML page

[abhi_madhani]

Hi Phpfreaks,

 

I have written this following code, it take any given URL of, and searches and list all 'ABC' links found in that given page. Then it goes through each 'ABC' link or page, searches and list all 'XYZ' links. The code works perfectly till here.

 

Now I am planning to recursive search, where if more 'ABC' links are present inside each 'ABC' page, it should search and list them and 'XYZ' links, and this could go to many levels deep. It is more or less similar to 'Recursive Directory Listing' which lists the directory structure of folder and files, but in HTML page.

 

I am still learning PHP Basic's, so any help even in simplifying my method of code would be grateful.

I have attached the dummy file that I have been working on, kindly find it attached.

 

Example ::

 

ABC page

ABC Link 1
	XYZ Link 1.1
	XYZ Link 1.2
	XYZ Link 1.3

ABC Link 2
	XYZ Link 2.1
	XYZ Link 2.2

ABC Link 3
	ABC Link 3-1
		XYZ Link 3-1.1
		XYZ Link 3-1.2
		XYZ Link 3-1.3

	ABC Link 3-2
		XYZ Link 3-2.1
		XYZ Link 3-2.1
		XYZ Link 3-2.1

	XYZ Link 3.1
	XYZ Link 3.2

ABC Link 4

 

 

My code is as follows ......

 

<?php

$url = "abclistA.html";
$needle = "abc"; $needle1 = "xyz";
echo '<table border="1">';

ABCfound:
$acontents = file_get_contents($url);

if (strpos($acontents, $needle)==!false) {
	preg_match_all('/id\s*=\s*\"abcs\".*?<\/table>a/isU',$acontents,$amatches);
	preg_match_all('/<a\s*href\s*=\s*\"(.*)\"\s*>\s*(.*)<\/a>/iSU',$amatches[0][0],$abc);

	foreach ($abc[0] as $akey => $abcrecord) {
		echo '<tr><td>'.$abc[2][$akey].'</td></tr>';

		$xcontents = file_get_contents($abc[1][$akey]);
		if(strpos($xcontents, $needle1)!==false) {

			preg_match_all('/id\s*=\s*\"xyz\".*?<\/table>x/isU',$xcontents,$xmatches);
			preg_match_all('/<a\s*href\s*=\s*\"(.*)\"\s*>\s*(.*)<\/a>/iSU',$xmatches[0][0],$xyz);

			foreach ($xyz[0] as $xkey => $xyzrecord) {
				echo '<tr><td>'.$xyz[2][$xkey].'</td></tr>';
			}

			// Planning to use this 'goto' shortcut, that when it again find ABC link inside ABC page, 
			// 	it should go to begining of this code and rerun it.
			// However this time $url will be changed with suburl that needs to scanned.
			// This doesn't seem to work.
			/*if (strpos($xcontents, $needle)==!false) {
				$url = $abc[1][$akey];
				echo " S-MF ";
				goto ABCfound;
			} else { echo " S-MNF "; } */

		} else { echo " SNF ";	}

	}
} else { echo " MNF "; }

echo '</table>';

?>
