是否可以让XPath表达式包含多个包含不同元素值的表达式？
<data>
<person>
<firstname>Kerry</firstname>
<lastname>Packer</lastname>
<address>Crown</address>
<person>
<person>
<firstname>Kerry</firstname>
<lastname>Murdoch</lastname>
<address>California</address>
<person>
<data>
$xml = simplexml_load_string($data);
$elements = $xml->xpath("(//person)[firstname[contains(.,'Kerr')]] and [lastname[contains(.,'och')]]");
目前,上面的XPath表达式被标记为无效.但是,如果我将它与一个元素一起使用,
$xml->xpath("(//person)[firstname[contains(.,'Kerr')]]");
然后它工作正常.
你只是想要
//person[contains(firstname,'Kerr') and contains(lastname,'och')]
