如何使用 SimpleXML 解析 XML 忽略错误 [英] How to parse an XML ignoring errors with SimpleXML

问题描述

我的 .xml 文档经常包含错误.无论如何，我想解析我的文档直到出现错误或尝试自动修复错误.那可能吗?

Often my .xml document contains errors. I would want to parse my document anyway up to errors or try to fix errors automatically. Is that possible?

我已经试过了，但它不起作用

I have tried this, but it isn't working

  $xml = simplexml_load_file($url, "SimpleXMLElement", array(LIBXML_NOERROR, LIBXML_ERR_NONE));

    if (!$xml) {
        echo "Failed loading XML\n";
        foreach(libxml_get_errors() as $error) {
            echo "\t", $error->message;
        }
    }

推荐答案

来自 PHP DOC simplexml_load_file 选项应该是 int 而不是数组

From PHP DOC simplexml_load_file options should be int not array

替换

$xml = simplexml_load_file($url, "SimpleXMLElement", array(LIBXML_NOERROR, LIBXML_ERR_NONE));
                                                       ^------- You are using array

与

$xml = simplexml_load_file($url, "SimpleXMLElement", LIBXML_NOERROR |  LIBXML_ERR_NONE);

您也可以使用 Tidy 包.

示例 bad.xml

<Family>
    <name>Hankre</name>
    <adults>2</adults>
    <kids > 16 </kids>
    <food>
        <tag>Nice </tag>
        <tag>Food </tag>
        <tag />

修复 XML

$config = array(
    'indent' => true,
    'clean' => true,
    'input-xml'  => true,
    'output-xml' => true,
    'wrap'       => false
    );

$tidy = new Tidy();
$xml = $tidy->repairfile($badXML, $config);
echo $xml;

输出

<Family>
    <name>Hankre</name>
    <adults>2</adults>
    <kids>16</kids>
    <food>
        <tag>Nice</tag>
        <tag>Food</tag>
        <tag />
    </food>
</Family>
