将制表符更改为 XML 文件中的空格

Question

在创建了许多文件之后，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还有标签。我想将它们从制表符转换为空格。

对于 Java 文件很简单：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，还可以尝试“改进格式”，这会破坏事情：

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'>

          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中的一个XML文件，如何将制表符转换为空格，不做其他改动？

Answer 1

你的方法是对的，但首先，你必须自定义 XML 格式：

• 打开Window > Preferences > XML > XML files > Editor。
• 选中format comments 并取消选中Join lines。 （这应该缩进 cmets 并删除相邻的空格等，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 format comments。）
• 选择Indent using spaces并设置indentation size。

现在您可以按[SHIFT][CTRL][F] 来格式化您的 XML 文件。

Answer 2

好吧，如果您是手动操作，并且不想要自动脚本，只需在您的 XML 文件中编写一个选项卡，复制它然后 ctrl + f > 替换，将选项卡粘贴到查找内容和替换为的空间中，然后全部替换。那是如果您不想用脚本替换它。

Answer 3

Search -> Search... (或 Ctrl+H) -> File Search,

检查Regular expression，

将\t设置为Containing text:，

将*.xml设置为File name patterns，

点击Replace...，设置 （根据需要放置空格）-> OK。

完成。享受。
