Question

我自己教PHP用于一个小项目。我需要将源HTML文件（可能有很多）中的所有标记转换为自定义XML。我一直在尝试使用DOMDocument类，但似乎无法正常工作。

举个例子，我需要转换

<img class="alignnone size-large wp-image-23904" src="https://picnic.ly/wp-content/uploads/2017/01/Screen-Shot-2560-01-27-at-2.32.06-PM-1024x572.png" alt="this is a picture" width="1024" height="574" />

要

<image>
<description>VALUE FROM ALT</description>
<url>VALUE FROM SRC</url>
</image>

希望对此有所帮助......先谢谢！

Answer 1

使用以下代码获取XML字符串：

<?php
// We use dom document to load it as an php object
$document = new DOMDocument();
$document->loadHTML('<img class="alignnone size-large wp-image-23904" src="https://picnic.ly/wp-content/uploads/2017/01/Screen-Shot-2560-01-27-at-2.32.06-PM-1024x572.png" alt="this is a picture" width="1024" height="574" />');
$img = $document->getElementsByTagName("img")->item(0);
// The Wrapper for your xml
$xml = "<image>\n";
for ($i = 0; $i < $img->attributes->length; $i++) {
    $attribute = $img->attributes->item($i);
    $name = $attribute->name;
    $value = $attribute->textContent;
    // Indent the element
    $xml .= "    ";
    // Create the element
    $xml .= "<" . $name . ">";
    $xml .= $value;
    $xml .= "</" . $name . ">";
    // Break line at end
    $xml .= "\n";
}
$xml .= "</image>";
echo $xml;

结果：

<image>
    <class>alignnone size-large wp-image-23904</class>
    <src>https://picnic.ly/wp-content/uploads/2017/01/Screen-Shot-2560-01-27-at-2.32.06-PM-1024x572.png</src>
    <alt>this is a picture</alt>
    <width>1024</width>
    <height>574</height>
</image>
