正则表达式匹配行以空格开头，第一个字符不是数字(Regex match line starting with whitespace and first character is non-digit)

 我试图创建一个正则表达式，它只匹配以空格开头的行，然后有1-4个非数字作为第一个字符，然后在数字后面至少有一个或多个空格。 此正则表达式的目的是在Notepad ++的“查找和替换”选项中使用它来删除所有不以空格开头的行，然后将一个数字作为行中的第一个字符。  
 我现在拥有的是允许我匹配以空白开头的行，并跟随一组数字和另一个空格。 但是，这些是我想保留的路线。 我如何修改以下正则表达式，以便它匹配除这些行之外的其他所有内容？  
/^([\s]+\d[\s]|[\s]+\d\d[\s]|[\s]+\d\d\d[\s])/gm
 
 这里是我们使用正则表达式的数据的一个例子。 正则表达式只能匹配不以1,2,49,50,99和100开头的行。请注意，以“第40位”和“2017/5/23/2017”开头的行应匹配。

 因此，如果我们在Notepad ++中使用正则表达式来查找匹配的字符串/行并替换（删除）它们，那么期望的最终结果如下（换句话说，下面的行不会匹配正则表达式）：

 任何援助将不胜感激。 

I am trying to create a regex that will only match lines that start with whitespace, then have 1-4 non-digits as the first characters, and then at least one or more spaces after the digits. The purpose of this regex is to use it in the "Find and Replace" option of Notepad++ to remove any lines that do not start with space(s) and then have a number as the first character in the line. 
What I have now is allowing me to match the lines that start with whitespace and are followed with a group of digits and another space. However, these are the lines I want to keep. How can I modify the following regex so that it will match everything else other than these lines?  
/^([\s]+\d[\s]|[\s]+\d\d[\s]|[\s]+\d\d\d[\s])/gm
 
Here's an example of the data we're using the regex on. The regex should only match the lines that DO NOT start with 1, 2, 49, 50, 99 and 100. Note that the lines that start with "40th" and "5/23/2017" should match. 
                                                                      Page 1

So if we used the regex in Notepad++ to find the matching strings/lines and replace (delete) them, the desired end result would be as follows (in other words, the following lines would NOT match the regex): 
    1   1/153  M0139 1:15:08 2:05:50 2:29:20   2:29:20  5:42 Eric
    2   2/153  M0139 1:15:07 2:06:29 2:29:56*  2:29:56  5:44 Bryan
   49   8/77   M4049 1:36:48 2:54:03 3:37:02   3:36:59  8:17 Joshua
   50  28/153  M0139 1:49:45 3:03:56 3:37:38#  3:37:22  8:18 Brian
   99   1/16   M6069 1:56:30 3:15:24 3:51:06   3:50:46  8:49 Paul
  100   3/35   F5059 1:50:06 3:11:37 3:51:03   3:50:47  8:49 Ashley
  101   4/35   F5059 1:55:26 3:16:37 3:56:03   3:55:57  9:14 Joan
 
Any assistance would be greatly appreciated.

 我不熟悉IntelliJ，但是，我看到有一个控制台调试工具 ，您可以在执行时访问变量值。 只需停止您想要的执行，并使用它来访问faces上下文并使用其名称获取托管bean：  
  FacesContext context = FacesContext.getCurrentInstance();
  context.getApplication().evaluateExpressionGet(context, "#{" + beanName + "}", Object.class);
 
 使用CDI时，您可以执行以下操作：  
@Inject
private Bean bean;
 
 得到了这个答案 。  
 问候。 

I'm not familiar with IntelliJ, however, I saw there's a console debug tool, where you can access variable values while executing. Just stop the execution where you want and use it to access the faces context and get the managed bean using its name: 
  FacesContext context = FacesContext.getCurrentInstance();
  context.getApplication().evaluateExpressionGet(context, "#{" + beanName + "}", Object.class);
 
When using CDI, you can do it like below: 
@Inject
private Bean bean;
 
Got from this SO answer.
