xml - 将 XML 文件中的制表符更改为空格

Question

创建许多文件后，我将 Eclipse 配置更改为 use spaces instead of tabs 。它有效:我写的新东西使用空格。但是我昨天写的文件当然仍然有选项卡。我想将它们从制表符转换为空格。

对于 Java 文件，这很简单:打开文件，按 CTRL+a，按 CTRL+i，完成。

但是对于 XML 文件该怎么做呢？与 Java 不同，对于 XML 文件，CTRL+a/CTRL+i 不仅可以转换制表符，而且还尝试“改进格式”，这会破坏一切:

初始代码:

<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE beans PUBLIC '-//SPRING//DTD BEAN//EN' 'http://www.springframework.org/dtd/spring-beans.dtd'>

    <bean id="webscript.helloworld.get"
          class="com.example.HelloWorldWebScript"
          parent="webscript">
    </bean>
</beans>

在 CTRL+a/CTRL+i(或 CTRL+SHIFT+f)之后:

<?xml version='1.0' encoding='UTF-8'?>

问题:对于 Eclipse 中的 XML 文件，如何将制表符转换为空格，而不进行其他更改？

Answer 1

你的方法是对的，但首先，你必须自定义 XML 格式:

• 打开窗口 > 首选项 > XML > XML 文件 > 编辑器。
• 选中格式注释并取消选中连接行。 (这应该缩进注释并删除相邻的空格，从而保留现有的换行符。但如果您对结果感到不舒服，请取消选中格式注释。)
• 选择使用空格缩进并设置缩进大小。

现在您可以按[SHIFT][CTRL][F]格式化您的XML文件。
