如何使用正则表达式匹配多行？ [英] How to match multiline using regex ?

问题描述

＃{{< div class => {{Meth [＃0＃]}}< / div>}}＃
< div class =form -group form-col-2> 
＃{{< div class =form-group-inline> 
< label> {{ABCDEF}}< / label> 
< div class =inpt> 
 {{?? DropList ??}} 
 
 {{?? DropList ??}} 
< / div> 
< / div>}}＃
< / div> 
< div class =form-group form-col-2> 
＃{{< div class =form-group-inline> 
< label> {{DEFGHI}}< / label> 
< div class =inpt> 
 {{?? DropList ??}} 
 
 {{?? DropList ??}} 
< / div> 
< / div>}}＃
< / div> 

我有什么尝试过：



i尝试了下面的表达但没有得到所有数学。

（？：\ ＃\ {\ {）（？：。*）（？：\} \} \＃）$ 

我想要的是

1）

＃{{< div class => {{Meth [＃0＃]}}< / div>}} ＃

2）

＃{{< div class =form-group-inline> 
< label> {{ABCDEF}}< / label> 
< div class =inpt> 
 {{?? DropList ??}} 
 
 {{?? DropList ??}} 
< / div> 
< / div>}}＃

3）

＃{{< div class =form-group-inline > 
< label> {{DEFGHI}}< / label> 
< div class =inpt> 
 {{?? DropList ??}} 
 
 {{?? DropList ??}} 
< / div> 
< / div>}}＃

解决方案

我想要的是

1）

＃{{< div class => {{Meth [＃0＃]} }< / div>}}＃<$ pre> 
 
 2）
＃{{< div class =form-group-inline> 
< label> {{ABCDEF}}< / label> 
< div class =inpt> 
 {{?? DropList ??}} 
 
 {{?? DropList ??}} 
< / div> 
< / div>}}＃
 
 
 3）
＃{{< div class =form-group-inline > 
< label> {{DEFGHI}}< / label> 
< div class =inpt> 
 {{?? DropList ??}} 
 
 {{?? DropList ??}} 
< / div> 
< / div>}}＃

只是一些有趣的链接，可以帮助构建和调试RegEx。

这是一个链接到RegEx文档：

perlre - perldoc.perl.org [ ^ ]

以下是帮助构建RegEx并调试它们的工具的链接：

.NET正则表达式测试程序 - 正则表达式风暴 [ ^ ]

Expresso正则表达式工具 [ ^ ]

RegExr：Learn，Build，&测试RegEx [ ^ ]

此节目RegEx是一个很好的图表，它非常有助于理解RegEx的作用：

Debuggex：在线可视正则表达式测试器。 JavaScript，Python和PCRE。 [ ^ ]

你的正则表达式似乎不对。正则表达式需要在＃{和}＃之间查找字符串。这是一个工作示例。

#{{<div class="">{{Meth[#0#]}}</div>}}#
<div class="form-group form-col-2">
	#{{<div class="form-group-inline">
		<label>{{ABCDEF}}</label>
		<div class="inpt">
		{{??DropList??}}
			
		{{??DropList??}}
		</div>
	</div>}}#                                        
</div>
<div class="form-group form-col-2">
	#{{<div class="form-group-inline">
		<label>{{DEFGHI}}</label>
		<div class="inpt">
		{{??DropList??}}
			
		{{??DropList??}}
		</div>
	</div>}}#                                       
</div>

What I have tried:

i tried following expression but not get all mathces.

(?:\#\{\{)(?:.*)(?:\}\}\#)$

what i want is
1)

#{{<div class="">{{Meth[#0#]}}</div>}}#

2)

#{{<div class="form-group-inline">
		<label>{{ABCDEF}}</label>
		<div class="inpt">
		{{??DropList??}}
			
		{{??DropList??}}
		</div>
	</div>}}# 

3)

#{{<div class="form-group-inline">
		<label>{{DEFGHI}}</label>
		<div class="inpt">
		{{??DropList??}}
			
		{{??DropList??}}
		</div>
	</div>}}#

Just a few interesting links to help building and debugging RegEx.
Here is a link to RegEx documentation:

Here is links to tools to help build RegEx and debug them:

This one show you the RegEx as a nice graph which is really helpful to understand what is doing a RegEx:

The regular expression you have doesn't seem right. The regular expression need to look for string in between #{ and }# . Here is a working example.
