PHP转换< img>标记到自定义XML [英] PHP to convert <img> tag to custom XML

问题描述

我正在自学PHP来开发一个小项目。我需要将源HTML文件中的所有标记（可能有很多）转换为自定义XML。我一直在尝试DOMDocument类的东西，但似乎无法让东西正常工作。

I'm teaching myself PHP for a small project. I need to convert all of the tags in a source HTML file (there may be many) into custom XML. I've been trying out things with the DOMDocument class, but can't seem to get stuff to work right.

举例来说，我需要将

As an example, I need to convert

<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" />

至

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

想在这里提供一些帮助...提前致谢！

Would love some help on this ... thanks in advance!

推荐答案

使用下面的代码获取XML字符串：

Use below code to get XML string:

<?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;

以及结果：

and the result:

<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>
