PHP XMLWriter，如何插入换行符? [英] PHP XMLWriter, how to insert a line break?

问题描述

我正在使用 XMLWriter http://www.php.net/manual/en/book.xmlwriter.php 让我的网络客户端创建一个 XML 文件.一开始必须有一个元素有很多属性，像这样:

I'm using XMLWriter http://www.php.net/manual/en/book.xmlwriter.php to let my webclient create an XML File. In the beginning there has to be an element with very many attributes, like this:

$xml->startElement('registry-request');
$xml->writeAttribute('att1', 'long text');
$xml->writeAttribute('att2', 'long text');
$xml->writeAttribute('att3', 'long text');
$xml->writeAttribute('att4', 'long text');

所以 XML 文件中的那部分看起来像这样:

So that part in the XML file will look something like this:

<registry-request att1="long text" att2="long text" att3="long text" att4="long text">

真实输入看起来很糟糕.

Which with real input looks quite terrible.

我宁愿这样:

<registry-request att1="long text" att2="long text" 
att3="long text" att4="long text">

我在 XMLWriter php.net 文档中没有找到解决方案，有人知道如何做到这一点吗?只需添加典型的换行命令，例如:

I didn't find a solution in the XMLWriter php.net documentation, anyone got an idea how to do this? Just adding typical linebreak commands like:

$xml->writeAttribute('att2', 'long text\n');

没有帮助.

谢谢.

推荐答案

实际上 $xml->setIndent(1); 就是这样做的.令人惊讶！

Actually the $xml->setIndent(1); does exactly that. Surprisingly!
