Getting the href attribute and text of certain kind of links - php

Question

Of these four links:
<img border="0" src="imagenes/flech.gif" width="6" height="8">
Albano Y Romina Power<br>
<img border="0" src="imagenes/flech.gif" width="6" height="8">
Armando Manzanero<br>
<a name="inicio21" href="musica-Merengue-de-Banda_Cuisillos.html">
<img border="0" src="imagenes/flech.gif" width="6" height="8">Banda Cuisillos</a><br>
Baladas Alternativas<br>
I'm trying to capture the href value and the text of the link of the three first, leaving out the fourth link, in other words i'm trying to get this:
escuchar-baladas-de-Albano_Y_Romina_Power.html Albano Y Romina Power
escuchar-baladas-de-Armando_Manzanero.html Armando Manzanero
musica-Merengue-de-Banda_Cuisillos.html Banda Cuisillos
I was trying to make the most of the fact that the three first have imagenes/flech.gif and that way leave out the fourth, the thing that imagenes/flech.gif isn't in the same order. Here is my attempt to solve it where i get up to the href but include the fourth.
Thanks for any help

Answer 1

You should use an html parser and not a regex, try this:
<?php
$html = <<< EOF
<img border="0" src="imagenes/flech.gif" width="6" height="8">
Albano Y Romina Power<br>
<img border="0" src="imagenes/flech.gif" width="6" height="8">
Armando Manzanero<br>
<a name="inicio21" href="musica-Merengue-de-Banda_Cuisillos.html">
<img border="0" src="imagenes/flech.gif" width="6" height="8">Banda Cuisillos</a><br>
Baladas Alternativas<br>
EOF;
$dom = new DOMDocument();
#$dom->loadHTML($html);
# Iterate over all the <a> tags
foreach($dom->getElementsByTagName('a') as $link) {
$url = $link->getAttribute('href');
$text = preg_replace('/[\r\n]/sm', '', $link->nodeValue); // remove line breaks
//if doesn't contain the banned words...
if (!preg_match('/(Baladas Alternativas|another text to filter)/sm', $text)) {
echo $url ." ".$text. "\n";
}
}
?>

Answer 2

this code will get the first 3 links
$a='<img border="0" src="imagenes/flech.gif" width="6" height="8">Albano Y Romina Power<br><img border="0" src="imagenes/flech.gif" width="6" height="8">Armando Manzanero<br><a name="inicio21" href="musica-Merengue-de-Banda_Cuisillos.html"><img border="0" src="imagenes/flech.gif" width="6" height="8">Banda Cuisillos</a><br>Baladas Alternativas<br>';
preg_match_all('/<a.*?href="(.+?)">(?:<img.*\d+">)?(.+?)<\/a>/',$a,$match);
echo $match[1][0] . " " . $match[2][0]."<br>";
echo $match[1][1] . " " . $match[2][1]."<br>";
echo $match[1][2] . " " . $match[2][2]."<br>";
