Question

我编译了一个XSL文档，将自定义XML文档转换为GraphML（带有一些yEd Graph Editor的附加元数据）。转换按预期工作并完成，但有一个问题。无论我使用哪种工具执行转换，结果文档都由单行组成，因此每次执行转换时都必须对其进行格式化。我的问题是：

如何调整我的XSL文档以获得漂亮的XML文档？

OR

我做错了什么？

我的XSL代码如下：

我正在使用Notepad ++“XML Tools”插件来转换和格式化我的文档。我们欢迎任何建议将XSLT转换与格式化结果结合到我的工作流程（以编程方式或其他方式）。

Answer 1

在xsl：stylesheet和xsl：template之间尝试<xsl:method output="xml" indent="yes"/>。对于某些处理器，它可能有效。

（但是对于非缩进的XML，你的问题是什么？）

Answer 2

更改此部分：

<xsl:stylesheet version="1.0" encoding="UTF-8" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

为：

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0" encoding="utf-8" indent="yes"/>
