嗯,这是html代码:
<?
$html ='<table cellspacing="0" cellpadding="0" class="mytable">
<tr>
<th class="first-td">Home <span>Live</span></th>
<th>type</th>
<th>Status</th>
</tr>
<tr>
<td width="40%" class="first-td">text1</td>
<td>info</td>
<td class="status"><span class="identify">asdf2</span></td>
</tr>
<tr>
<td width="40%" class="first-td">text2</td>
<td>info</td>
<td class="status"><span class="identify2">asdf</span></td>
';
$pattern = '/<span class="identify">(.*?)<'/span>/im';
preg_match_all($pattern, $html, $matches);
print_r($matches);
?>
但我想要的是取回单词文本,这是标识类的单元格中的 td。或者,如果类是识别打印 1 时更容易,或者如果它是识别 2,请按 0。
所以我像这样输入伪代码:
If class-identify print the td-class=first-td of that cell
我可以推荐你使用xpath,就像在这个例子中一样。
