如何使用 PHP 修复 XML 解析错误？ [复制]

Question

可能重复：
PHP library for parsing XML with a colons in tag names?

我有下面显示的 xml，我想解析出产品标题。当我使用下面的 php 代码时，我得到“Parse error: syntax error, unexpected ':' in /home/content/c/a/s/cashme/html/buylooper/xml.php on line 5”，因为“：”位于标签中。我该如何解决这个问题？

*更新：我已经得到了第一部分的答案，但是在如何解析出 xml 标记的属性时遇到了麻烦。我遇到问题的标签是“s:images”标签内的“s:image”标签（链接属性）。

    <?php
    $url = 'xml-file.xml';
    $xml = simplexml_load_file($url);
    $title = $xml->entry[0]->s:product->s:title; 
    //print
    echo '<br/>';
    echo $title;
    ?>

Answer 1

首先解析命名空间。

$namespaces = $xml->getNameSpaces(true);
$s = $xml->children($namespaces['s']);
echo (string)$s->product->title. "\n";
echo (string)$s->product->images->image->attributes()->link;

Answer 2

您需要使用 获取正确的命名空间。这是未经测试的，但可能会奏效：

$url = 'xml-file.xml';
$xml = simplexml_load_file($url);
$namespaces = $xml->entry->getNameSpaces(true);

// Get children of the correct namespace
$s = $xml->entry[0]->children($namespaces['s']);
$title = $s->product->title;

//print
echo '<br/>';
echo $title;
