hsa*_*ite 2 html php hyperlink
我想获取一串文本并查找所有超链接标记,获取其href值,并使用href属性的值替换整个超链接标记.
很多可能性.例如,通过使用DOM扩展,DOMDocument :: loadhtml()和XPath(尽管getElementsbyTagName()在这种情况下就足够了).
<?php
$string = '<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"
"http://www.w3.org/TR/html4/strict.dtd"><html><head><title>...</title></head><body>
<p>
mary had a <a href="little">greedy</a> lamb
whose fleece was <a href="white">cold</a> as snow
</p>
</body></html>';
$doc = new DOMDocument;
$doc->loadhtml($string);
$xpath = new DOMXPath($doc);
foreach( $xpath->query('//a') as $a ) {
$tn = $doc->createTextNode($a->getAttribute('href'));
$a->parentNode->replaceChild($tn, $a);
}
echo $doc->savehtml();
