Hi
I have an situation where I have to extract some data from a website. On the whole page, there is a <a> tag with "target = _blank" while the others are simple <a> tags.
I want ot get the HREF of the <a> which has the attribute target = _blank,
Please let me know how this can be matched via Xpath. Or if Xpath can not do that. Please help
This seems to work:
PHP Code:<?php
$content = '
<a href="asd.php">asd</a>
<a href="asd.html" target="_blank">asd</a>
<a href="asd2.php">asd</a>
<a href="asd2.html" target="_blank">asd</a>';
// Start of open tag
$regex = '~<a href="';
// Match a url
$regex .= '(.*?)"';
// Match any attributes
$regex .= '([a-zA-Z0-9\=\-\"\s]*)';
// Match target="_blank"
$regex .= ' ?target="_blank" ?';
// Any attributes again
$regex .= '([a-zA-Z0-9\=\-\"\s]*)';
// End of open tag
$regex .= '>~i';
preg_match_all($regex, $content, $matches);
print_r($matches[1]);

I'm not really up on XPath, but this seems logical:
//a[@target="_blank"][0]

Here you go, a quick PHP, SimpleXML example for you:
PHP Code:<?php
$sData = '
<html>
<head>
<title>Sample</title>
</head>
<body>
<a href="path/to/something">One</a>
<a href="path/to/something" target="_blank">Two</a>
<a href="path/to/something">Three</a>
<a href="path/to/something" target="_blank">Four</a>
<a href="path/to/something">Five</a>
</body>
</html>
';
$oDoc = new SimpleXMLElement($sData);
$oElements = $oDoc->xpath("//a[@target='_blank']");
print_r($oElements);
/*
Array
(
[0] => SimpleXMLElement Object
(
[@attributes] => Array
(
[href] => path/to/something
[target] => _blank
)
[0] => Two
)
[1] => SimpleXMLElement Object
(
[@attributes] => Array
(
[href] => path/to/something
[target] => _blank
)
[0] => Four
)
)
*/
?>
