我需要xml节点的完整路径 我在this question看到了答案,但我无法使用它。
我在php web测试器上使用的代码下面没有成功:
$xml = <<<EOF
<root>
<First>
<Martha>Text01</Martha>
<Lucy>Text02</Lucy>
<Bob>
<Jhon>Text03</Jhon>
</Bob>
<Frank>One</Frank>
<Jessy>Two</Jessy>
</First>
<Second>
<Mary>
<Jhon>Text04</Jhon>
<Frank>Text05</Frank>
<Jessy>Text06</Jessy>
</Mary>
</Second>
</root>
EOF;
$MyXml = new SimpleXMLElement($xml);
$Jhons = $MyXml->xpath('//Jhon');
foreach ($Jhons as $Jhon){
echo (string) $Jhon;
//No one of the following works
echo (string) $Jhon->xpath('./node()/path()');
echo (string) $Jhon->xpath('./path()');
echo (string) $Jhon->xpath('.path()');
echo (string) $Jhon->path();
echo '<br/> ';
}
我需要:&#34; / root / First / Bob / Jhon&#34;和&#34; / root / Second / Mary / Jhon&#34;

你可以使用更强大的DOM(基于PHP的DOMDocument)api来做到这一点......
$MyXml = new SimpleXMLElement($xml);
$Jhons = $MyXml->xpath('//Jhon');
foreach ($Jhons as $Jhon){
$dom = dom_import_simplexml($Jhon);
echo $dom->getNodePath().PHP_EOL;
}
dom_import_simplexml($Jhon)
转换节点,然后getNodePath()
显示路径...
这给出了(例如)
/root/First/Bob/Jhon
/root/Second/Mary/Jhon
或者如果您只想坚持使用SimpleXML,您可以使用XPath轴祖先或自我列出当前节点和每个父节点......
$MyXml = new SimpleXMLElement($xml);
$Jhons = $MyXml->xpath('//Jhon');
foreach ($Jhons as $Jhon){
$parent = $Jhon->xpath("ancestor-or-self::*");
foreach ( $parent as $p ) {
echo "/".$p->getName();
}
echo PHP_EOL;
}
