正则表达式获取内部文本

发布于 2024-12-09 21:44:15 字数 344 浏览 3 评论 0原文

我一直试图在句子中获取第一个位置名称。所需的位置名称将恰好从第一个句子的第二个大写字母开始，然后恰好在第一个点（。）之前

结束示例：

 It is located at Supreme Court. Follow by some other text. 
                  ^           ^

所需的输出

最高法院

抱歉，我无法向您展示我目前掌握的一段代码。经过一个小时的尝试，我没有得到任何具体的结果。

如果您能用 Ruby 展示代码示例，我们将不胜感激。

原文

I have been trying to grab a first location name inside the sentences. The desired location name will exactly starts at the 2nd capital of the first sentence and then precisely end before the first dot(.)

Example:

 It is located at Supreme Court. Follow by some other text. 
                  ^           ^

Desired out put

Supreme Court

Sorry I can't show you a piece of code that I've got so far. After an hour of trying, I got nothing in concrete.

If you show the code example in Ruby would be highly appreciated.

这个正则表达式：

regexp = /^.*?[A-Z].*?([A-Z].*?)\./
match = regexp.match(subject)
if match
    match = match[1]
else
    match = ""
end

将产生：Supreme Court

我从匹配第一个大写字母的字符串开头开始，而忽略其他一切。然后，我匹配第二个大写字母并将结果保存到反向引用 1 中，直到第一个点。

This regex :

regexp = /^.*?[A-Z].*?([A-Z].*?)\./
match = regexp.match(subject)
if match
    match = match[1]
else
    match = ""
end

Will produce : Supreme Court

I start from the start of the string matching the first capital while ignoring everyhting else. I then match the 2nd capital and save the result into backreference 1 until the first dot.

s = 'It is located at Supreme Court. Follow by some other text.'
m = s.match /[A-Z][^A-Z]+([A-Z][^\.]+)/
result = m[1] #Supreme Court

s = 'It is located at Supreme Court. Follow by some other text.'
m = s.match /[A-Z][^A-Z]+([A-Z][^\.]+)/
result = m[1] #Supreme Court

这对我有用：

irb(main):001:0> location = "It is located at Supreme Court. Follow by some other text."
=> "It is located at Supreme Court. Follow by some other text."
irb(main):002:0> location.match(/[^A-Za-z][\bA-Z][\w\s]*\./)
=> #<MatchData "Supreme Court.">

This worked for me:

irb(main):001:0> location = "It is located at Supreme Court. Follow by some other text."
=> "It is located at Supreme Court. Follow by some other text."
irb(main):002:0> location.match(/[^A-Za-z][\bA-Z][\w\s]*\./)
=> #<MatchData "Supreme Court.">

试试这个：

s = 'It is located at Supreme Court. Follow by some other text.'
/[A-Z].+?([A-Z].*)\..+?/.match(s)[1]

Try this:

s = 'It is located at Supreme Court. Follow by some other text.'
/[A-Z].+?([A-Z].*)\..+?/.match(s)[1]

这假设字符串的开头没有空格，因此它会查找紧随空格之后的第一个大写字母并抓取任何内容，直到找到第一个句点。

str = "It is located at Supreme Court. Follow by some other text."
m = str.match(/\s([A-Z].*?)\./)
location = m.nil? ? "" : m[1] #just in case there's no match

p location #=> Supreme Court

This assumes there's no space at the beginning of the string, therefore it looks for the first capital letter that comes right after a space and grabs anything until the first period it finds.

str = "It is located at Supreme Court. Follow by some other text."
m = str.match(/\s([A-Z].*?)\./)
location = m.nil? ? "" : m[1] #just in case there's no match

p location #=> Supreme Court
