It is obvious I haven't had my caffeine yet. This is my last try to
get the pattern straight:
<?php
$html = <<<END_OF_HTML
<b>hello</b>
<b class="blah">hello</b>
<p>those</p>
<p class="blah">hello</p>
<a>hello</a>
<a href="url">this</a>
<a>rose</a>
<a href="regex yo">hello</a>
<a>nose</a>
<a id="2" href="regex yo">hello</a>
<p>that</p>
<p class="blah" title="whatever">hello</p>
END_OF_HTML;
$tags = array();
$tags[] = 'p';
$tags[] = 'a';
$attr = array();
$attr[] = 'class';
$attr[] = 'href';
$vals = array();
$vals[] = 'blah';
$vals[] = 'url';
$vals[] = 'yo';
$text = array();
$text[] = 'hello';
$text[] = 'this';
$text[] = 'that';
$tags = implode('|', $tags);
$attr = implode('|', $attr);
$vals = implode('|', $vals);
$text = implode('|', $text);
$pattern =
'/<('.$tags.')[^>]*('.$attr.')?[^>]*('.$vals.')?[^>]*>('.$text.')[^<\/]*<\/\1>/i';
echo $pattern."\n";
echo "--------------------\n";
preg_match_all($pattern, $html, $matches);
var_dump($matches);
?>
</clip>
I dont get why you added this
$tags[] = 'a';
Does that mean I will have to make tags like that for all the html
tags that i think will be on the page?
Hi,
I said before that the example could be a little bit overkill, but it
gives a quick example how to find any tag(s) given, with any
attribute(s) given and with any text given in between the opening and
closing tag.
And yes, it might be incomplete or maybe not even accurate, but it does
give you a headstart on your solution. There always will be people who
will give you a shorter, cleaner, more beautiful example, but I hope
that it was helpful for you or will be helpful for someone else.
