如何使用PHP修复XML解析错误？

Question

  

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

我有下面显示的xml，我想解析产品标题。当我使用下面的PHP代码时，我在第5行的/home/content/c/a/s/cashme/html/buylooper/xml.php中得到“解析错误：语法错误，意外”：' strong>“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，但是我在如何解析xml标签的属性方面遇到了麻烦。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

您需要使用获取正确的命名空间。这是未经测试的，但可能会成功：

$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;

Answer 2

首先解析名称空间。

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