在lxml中关闭一个没有文字的标签(Close a tag with no text in lxml)

在lxml中关闭一个没有文字的标签(Close a tag with no text in lxml)

我正尝试使用Python和lxml输出一个XML文件

但是，我注意到一件事，如果一个标签没有文本，它不会自动关闭。 一个例子是：

root = etree.Element('document') rootTree = etree.ElementTree(root) firstChild = etree.SubElement(root, 'test')

这个输出是：

<document> <test/> </document

我想要的输出是：

<document> <test> </test> </document>

所以基本上我想关闭一个没有文本但用于属性值的标签。 我怎么做？ 而且，这个标签叫什么？ 我会谷歌搜索它，但我不知道如何搜索它。

I am trying to output a XML file using Python and lxml

However, I notice one thing that if a tag has no text, it does not close itself. An example of this would be:

root = etree.Element('document') rootTree = etree.ElementTree(root) firstChild = etree.SubElement(root, 'test')

The output of this is:

<document> <test/> </document

I want the output to be:

<document> <test> </test> </document>

So basically I want to close a tag which has no text, but is used to the attribute value. How do I do that? And also, what is such a tag called? I would have Googled it, but I don't know how to search for it.

最满意答案

请注意， <test></test>和<test/>含义完全相同。 你想要的是测试标签实际上有一个包含单行换行的文本。 然而，一个没有文本的空标记通常被写为<test/> ，坚持它显示为<test></test>是没有意义的。

Note that <test></test> and <test/> mean exactly the same thing. What you want is for the test-tag to actually do have a text that consists in a single linebreak. However, an empty tag with no text is usually written as <test/> and it makes very little sense to insist on it to appear as <test></test>.
