使用DOM为一个元素创建多个属性 [英] Create multiple attribute for one Element with DOM

问题描述

如何为DOM元素创建多个属性？

How can I create more than one attribute for a DOM Element?

这里我有一个属性

$data = $xml->createElement('enclosure', $rssdata["nNr"]);
$enclosure = $xml->createAttribute('type');
$enclosure->value = 'image/jpeg';
$data->appendChild($enclosure);
$item->appendChild($data);

但是我需要两个属性，例如URL导出在这里

But I need two attributes like the export here for URL

<enclosure type="image/jpeg" url="">1</enclosure>

推荐答案

只需再添加三行：

$data = $xml->createElement('enclosure', $rssdata["nNr"]);

$enclosure = $xml->createAttribute('type'); # creating attribute 1
$enclosure->value = 'image/jpeg';           # setting value
$data->appendChild($enclosure);             # adding attribute to element

$url = $xml->createAttribute('url');  # creating attribute 2
$url->value = '';                     # setting value
$data->appendChild($url);             # adding attribute to element

$item->appendChild($data);

如果要添加许多属性，则可以考虑创建一个减少代码重复的函数。

If you have many attributes to add, you might consider creating a function to reduce code duplication.

您的变量名可能会令人困惑。如果重命名 $ enclosure 和 $ data ，您的代码可能会变得更清晰易读：

Your variable names may be confusing. If you rename $enclosure and $data your code might become clearer and easier to read:

$enclosureElement = $xml->createElement('enclosure', $rssdata["nNr"]);

$typeAttribute = $xml->createAttribute('type'); # creating attribute 1
$typeAttribute->value = 'image/jpeg';           # setting value
$enclosureElement->appendChild($typeAttribute); # adding attribute to element

$urlAttribute = $xml->createAttribute('url');  # creating attribute 2
$urlAttribute->value = '';                     # setting value
$enclosureElement->appendChild($urlAttribute); # adding attribute to element

$item->appendChild($enclosureElement);
