如何使用特殊格式将字符串拆分为子字符串？ [英] How Do I Split A String To Substring With Special Format?

问题描述

我有几个以下格式的字符串，需要分别提取每个单词及其标签怎么做？



string =word1（tag1）word2（tag2 ）word3（tag3）....

需要提取子字符串，例如：

str [0] =word1，str [1] =word2 ，str [3] =word3，....

tag [0] =tag1，tad [1] =tag2，tag [3] =tag3,. ...

I have several string with following format that need to extract each word and its tag separately How doing this?

string= " word1 (tag1) word2 (tag2) word3 (tag3) ... ."
needing to extracted substring such as:
str[0]="word1" , str[1]="word2", str[3]="word3" , ....
tag[0]="tag1" , tad[1]="tag2", tag[3]="tag3" , ....

推荐答案

可以有更好的方法来做到这一点，但你可以采取以下方法 -

There can be better way to do this but you may take following approach-

string originalString= "word1 (tag1) word2 (tag2) word3 (tag3)";
string[] tempArray=originalString.Split(' ');
string[] words=new string[((int)(tempArray.length/2))];
string[] tags=new string[((int)(tempArray.length/2))];

int indexWords=0;
int indexTags=0;

foreach(string str in tempArray)
{
  if(Array.IndexOf(tempArray,str)%2==0)
  {
    tags[indexTags]=str.Replace('(','').Replace(')','');
    indexTags++;
  }
  else
  {
    words[indexWords]=str;
    indexWords++;  
  }    
}

希望，它有帮助：）

使用正则表达式：

Use a Regex:

(?<str>.+?)(?<tag>\(.+?\))

应该将值分成str，tag对。

如果你然后使用Trim删除任何空格，然后通过循环或两个Linq分组到列表中声明。



注意：在上面的正则表达式中，反斜杠用于告诉正则表达式第二组内的那些是litteral open和close括号：但是，虽然它们在预览中可见，但它们在页面上不可见...

正则表达式字符串应如下所示：

Should separate the values into str, tag pairs.
If you then use Trim to remove any whitespace, and group then into lists via a loop or two Linq statements.

Note: in the Regex above, back slashes are used to tell the Regex that the ones inside the second group are litteral open and close brackets: However, while they are visible in the preview, they aren't visible on the page...
The Regex string should look like this:

(
?
<
s
t
r
>
.
+
?
)
(
?
<
t
a
g
>
\
(
.
+
?
\
)
)

删除所有换行符（我会将其报告为bug）。现在他们是可见。 ：叹气：

With all the line breaks removed (I'll report it as a bug).And now they are visible. :sigh:

string [] words;

words = new string [100];

int i，j，k = 0，l = 0;

string str =word1（tag1）word2（tag2）word3（tag3）;

words = str.Split（''）;



words = str.Split（''）;





for（i = 0; i< words.Length; i ++）

{

if（i％2 == 0）

{



Console.WriteLine（str+[++（k）+]+=+ words [i]）;

k = k + 1;

}

}



for（j = 0; j< words.Length; j ++）

{

if（ j％2！= 0）

{



Console.WriteLine（tag+[++（l） +]+=+字[j]）;

l = l + 1;

}

}

string[] words;
words = new string[100];
int i,j,k=0,l=0;
string str = "word1 (tag1) word2 (tag2) word3 (tag3)";
words = str.Split(' ');

words = str.Split(' ');


for (i = 0; i < words.Length; i++)
{
if (i % 2 == 0)
{

Console.WriteLine("str" + "[" + "" + (k) + "]" + "=" + words[i]);
k=k+1;
}
}

for (j = 0; j < words.Length; j++)
{
if(j%2!=0)
{

Console.WriteLine("tag" + "[" + "" + (l) + "]" + "=" + words[j]);
l=l+1;
}
}
