XPath with multiple contains on different elements
提问by TeaCupApp
Is it possible to have XPathexpression with multiple contains of different element values?
是否可以有XPath多个包含不同元素值的表达式？
XML
XML
<data>
<person>
<firstname>Kerry</firstname>
<lastname>Packer</lastname>
<address>Crown</address>
<person>
<person>
<firstname>Kerry</firstname>
<lastname>Murdoch</lastname>
<address>California</address>
<person>
<data>
PHP
PHP
$xml = simplexml_load_string($data);
$elements = $xml->xpath("(//person)[firstname[contains(., 'Kerr')]] and [lastname[contains(., 'och')]]");
Currently above XPathexpression is flagged as invalid. However if I use it with one element,
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')]]");
then it works fine.
然后它工作正常。

You simply want
你只是想要
//person[contains(firstname, 'Kerr') and contains(lastname, 'och')]
