help with regex pattern
i have multiple strings containing a link like:
<A HREF="http://www.testings2">testings2</A>
<A HREF="http://www.blabla">blabla</A>
<A HREF="http://www.gowick">gowick</A>
i want to use a regex pattern that gets the uri within the href.
i could do like:
/".*?"/
but then the "" will come along. is there a way to just get the uri within the HRE开发者_如何学编程F="" without using preg_replace function?
thanks!
preg_match_all('/href="([^"]+)/i', $str, $matches);
var_dump($matches);
not sure how to apply this in PhP but it works in perl
/<a href="([^"]+)".+/i;
I assume it to be
preg_match( '/<a href="([^"]+)".+/i;', $str, $matches);
$str=<<<EOF
<A href="http://
www.testings2">testings2</A> blah
<A HrEF=
"http://www.blabla">blabla</A> blah
<A HREF="http://www.gowick">gowick</A>
<A
HREF="http://www.testing3">testing3</A>
<a class="navigation" id="selected" href="http://somewhere.com"><xsl:value-of
select="title" /></a>
EOF;
$s = preg_split("/<\/A>/i",$str);
$s = preg_replace("/\n+/","",$s);
$uris = preg_grep("/HREF/i",$s);
foreach($uris as $v){
$fin = explode('">',$v);
$t=preg_split('/href="/i',$fin[0] );
print end($t)."\n";
}
output
# php test.php
http://www.testings2
http://www.blabla
http://www.gowick
http://www.testing3
http://somewhere.com
