Preg匹配2个字符串之间的任何东西

Question

I have to get the location of a number from this site

lookupexpert.com/search_phone?phone_number=7322691678

And i want a regex that matches anything inside

<p class="location">OCEAN GATE, NJ</p>

How do i do that?

This is what i did so far

<?php

$subject = file_get_contents("http://lookupexpert.com/search_phone?phone_number=7322691678");

$pattern = '#\<p class="location"\>(.+?)\<\/p\>#s';
preg_match($pattern, $subject, $matches, PREG_OFFSET_CAPTURE, 3);
print_r($matches);

?>

and also ... i tried with Xpath, and didn't worked so good, because it is not properly validated

/html/body/div/div[2]/div/ul/li[2]/p[4]

Answer 1

Try this:

$subject = file_get_contents( 'http://www.lookupexpert.com/search_phone?phone_number=7322691678');
preg_match_all( '#<p class="location">(.*?)</p>#', $subject, $matches);
var_dump( $matches[1][1]);

This outputs:

string(14) "OCEAN GATE, NJ"

Answer 2

Use this XPath

//p[@class='location']/text()

or this RegEx

(?<=<p class="location">)([^<>]+)(?=</p>)

code

preg_match_all('%(?<=<p class="location">)([^<>]+)(?=</p>)%', $subject, $result, PREG_PATTERN_ORDER);
$result = $result[1];

Answer 3

Try this one..

$string = '<p class="location">OCEAN GATE, NJ</p>';
$pattern = '/<p class="location">(.*)<\/p>/';

$preg = preg_match_all($pattern, $string, $match);
print_r($match);

Answer 4

Better not to rely on unreliable regex parsing the HTML and use a DOM parser instead. Use a code like this:

$doc = new DOMDocument();
libxml_use_internal_errors(true);
// assuming search_phone.html contains your saved HTML source
#$doc->loadHTMLFile('search_phone.html'); // loads your html
$xpath = new DOMXPath($doc);
$value = $xpath->evaluate("string(//li[starts-with(@class, 'recordItem')]/
                           p[@class='location']/text())"); 
echo "Location Name: [$value]\n"; // prints your location

OUTPUT:

Location Name: [OCEAN GATE, NJ]
