PHP-从字符串中删除XML标记

我将Oracle DB中的字符串值查询为PHP字符串，字符串周围有XML，如下所示：

<?xml version='1.0' encoding='UTF-8'?><root available-locales="en_US" default-locale="en_US"><Title language-id="en_US">Batman</Title></root>
<?xml version='1.0' encoding='UTF-8'?><root available-locales="en_US" default-locale="en_US"><Title language-id="en_US">Wonder Woman</Title></root>
<?xml version='1.0' encoding='UTF-8'?><root available-locales="en_US" default-locale="en_US"><Title language-id="en_US">Fantastic Four</Title></root>

最好的方法是什么

我本来想试试substr，但意识到我不知道结局是什么，因为每个标题都不一样。我也试过脱衣标签，但没用

---

谢谢

使用

preg\u replace

并捕获

id=“en\u US”>

和

之间的字符串作为替换项

<?php

$xml = <<<EOF
<?xml version='1.0' encoding='UTF-8'?><root available-locales="en_US" default-locale="en_US"><Title language-id="en_US">Batman</Title></root>
<?xml version='1.0' encoding='UTF-8'?><root available-locales="en_US" default-locale="en_US"><Title language-id="en_US">Wonder Woman</Title></root>
<?xml version='1.0' encoding='UTF-8'?><root available-locales="en_US" default-locale="en_US"><Title language-id="en_US">Fantastic Four</Title></root>
EOF;

$title = preg_replace('#.*id="en_US">(.*?)<.*#', '$1', $xml);
print $title;

您可以使用。这将返回一个，您可以从中获取
Title
属性：

$strXml = <<<XML
<?xml version='1.0' encoding='UTF-8'?><root available-locales="en_US" default-locale="en_US"><Title language-id="en_US">Wonder Woman</Title></root>
XML;

$simpleXmlElement = simplexml_load_string($strXml);
$title = (string)$simpleXmlElement->Title;
echo $title;

这将给你：

神奇女侠

$strXml = <<<XML
<?xml version='1.0' encoding='UTF-8'?><root available-locales="en_US" default-locale="en_US"><Title language-id="en_US">Wonder Woman</Title></root>
XML;

$simpleXmlElement = simplexml_load_string($strXml);
$title = (string)$simpleXmlElement->Title;
echo $title;

$doc = new DOMDocument();
$doc->loadXML($strXml);
echo $doc->getElementsByTagName("Title")[0]->nodeValue;
