块缩进正则表达式 [英] Block Indent Regex

问题描述

我在使用正则表达式时遇到问题.

我正在尝试实现一个正则表达式来只选择选项卡缩进块，但我找不到让它工作的方法:

示例:

INDENT(1)缩进(2)内容(一)内容(b)缩进(3)内容(c)

所以我需要这样的块:

INDENT(2)内容(一)内容(b)

AND

INDENT(3)内容(c)

我该怎么做?

真的很不错，差不多就是这样，这是我最初的需求:

表trtd若昂"若昂"td马科斯"

我需要单独的td"块，我可以调整你的例子吗?

解决方案

这取决于你想要做什么，但可能是这样的:

^(\t+)(\S.*)\n(?:\1\t.*\n)*

工作示例:http://www.rubular.com/r/qj3WSWK9JR>

模式搜索:

• ^(\t+)(\S.*)\n - 以制表符开头的一行(我也捕获了组中的第一行，只是为了看看效果), 其次是
• (?:\1\t.*\n)* - 带有更多标签的行.

同样，您可以使用 ^( +)(\S.*)\n(?:\1 .*\n)* 表示空格(示例).不过，混合使用空格和制表符可能会有点问题.

对于更新的问题，考虑使用 ^(\t{2,})(\S.*)\n(?:\1\t.*\n)*，对于 at行首至少有 2 个标签.

I'm having problems about a regexp.

I'm trying to implement a regex to select just the tab indent blocks, but i cant find a way of make it work:

Example:

INDENT(1)
    INDENT(2)
        CONTENT(a)
        CONTENT(b)
    INDENT(3)
        CONTENT(c)

So I need blocks like:

INDENT(2)
    CONTENT(a)
    CONTENT(b)

AND

INDENT(3)
    CONTENT(c)

How I can do this?

really tks, its almost that, here is my original need:

table
    tr
        td
            "joao"
            "joao"
        td
            "marcos"

I need separated "td" blocks, could i adapt your example to that?

解决方案

It depends on exactly what you are trying to do, but maybe something like this:

^(\t+)(\S.*)\n(?:\1\t.*\n)*

Working example: http://www.rubular.com/r/qj3WSWK9JR

The pattern searches for:

• ^(\t+)(\S.*)\n - a line that begins with a tab (I've also captured the first line in a group, just to see the effect), followed by
• (?:\1\t.*\n)* - lines with more tabs.

Similarly, you can use ^( +)(\S.*)\n(?:\1 .*\n)* for spaces (example). Mixing spaces and tabs may be a little problematic though.

For the updated question, consider using ^(\t{2,})(\S.*)\n(?:\1\t.*\n)*, for at least 2 tabs at the beginning of the line.
