Russian<div class="active make_link">1</div>
<div class="make_link digit"><a href="">2</a></div>
<div class="make_link digit"><a href="">3</a></div>
etc
to
<li class="active">1</li>
<li><a href="">2</a></li>
<li><a href="">3</a></li>
etc
Figured out how to replace the elements but not how to keep the class active.
$new_pagination = preg_replace('/<div[^>]*>(.*)<\/div>/U', '<li>$1</li>', $old_pagination);
Any ideas?
解决方案
Try this..You can do this using str_ireplace too
<?php
$html='<div class="active make_link">1</div>
<div class="make_link digit"><a href="">2</a></div>
<div class="make_link digit"><a href="">3</a></div>';
echo str_ireplace(array('<div','</div','class="active make_link"','class="make_link digit"'),array('<li','</li','active',''),$html);
其他提示
Or simple html dom:
require_once('simple_html_dom.php');
$doc = str_get_html($string);
foreach($doc->find('div') as $div){
$div->tag = 'li';
preg_match('/active/', $div->class, $m);
$div->class = @$m[0];
}
echo $doc;
This may seem a bit excessive, but it's a good use-case for XSLT:
$xslt = <<<XML
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="@*|node()">
<xsl:copy><xsl:apply-templates select="@*|node()" /></xsl:copy>
</xsl:template>
<xsl:template match="div">
<li>
<xsl:if test="@*[name()='class' and contains(., 'active')]">
<xsl:attribute name="class">active</xsl:attribute>
</xsl:if>
<xsl:apply-templates select="node()" />
</li>
</xsl:template>
</xsl:stylesheet>
XML;
It uses the identity rule and then overrides handling for <div>, adding a class="active" for nodes that have such a class name.
$xsl = new XSLTProcessor;
$doc = new DOMDocument;
$doc->loadXML($xslt);
$xsl->importStyleSheet($doc);
$doc = new DOMDocument;
$html = <<<HTML
<div class="active make_link">1</div>
<div class="make_link digit"><a href="">2</a><div>test</div></div>
<div class="make_link digit"><a href="">3</a></div>
HTML;
$doc->loadHTML($html);
echo $xsl->transformToDoc($doc)->saveHTML();
