REGEX仅用于数据和结束标记 [英] REGEX for only data and end tag

问题描述

<$ p $ <$ p

例如

p> 输入：
-----------------
< p> ABC< p>
-----------------
输出将是
-----------------
ABC< p>

-----------------


它只会删除第一个para

para标签，而不是用于第二个para

标签，其间的所有文本都是相同的。

我想在此提及，我正在寻找

 < p> ABC< p> 
  

不适用

 < p为H. ABC< / p为H. 
  

它用于具有不规则

标签的特定文本文件

示例：

我有很大的xhtml文件，例如...

 < p为H. SCET< / p为H. 
< p>晴天< / p> 
< p> <！ - 此标签将被移除 - > 
< p> <！ - 此标签将被移除 - > 
< p>标记< / p> 
< p>托马斯< / p> 
  

它是一个完整的XHTML file.having body head标签
这里只有问题是
额外标签
i期待这样的输出

 < p> scet< / p> 
< p>晴天< / p> 
 
< p>标记< / p> 
< p>托马斯< / p> 
  

解决方案

/ p>

  public static class XHTMLCleanerUpperThingy 
 {
 private const string p =< p>; 
 private const string closingp =< / p>; 
 
 public static string CleanUpXHTML（string xhtml）
 {
 StringBuilder builder = new StringBuilder（xhtml）; 
 for（int idx = 0; idx< xhtml.Length; idx ++）
 {
 int current;如果（（current，xhtml.IndexOf（p，idx））！= -1）
 {
 int idxofnext = xhtml.IndexOf（p，current + p.Length）; 
 int idxofclose = xhtml.IndexOf（closingp，current）; 
 
 //如果有下一个< p>标记
 if（idxofnext> 0）
 {
 //如果下一个结束标记比下一个< p>更远，标记
 if（idxofnext< idxofclose）
 {
 for（int j = 0; j< p.Length; j ++）
 {
 builder [current + j] =''; 
} 
} 
} 
 //如果没有最终结束标记
 else if（idxofclose <0）
 {
 for（int j = 0; j  {
 builder [current + j] =''; 
 
 
 
 
 
 return builder.ToString（）; 
} 
} 
  

I am looking for REGEX which will give me data along with the end tag

e.g.

input:
-----------------
<p>ABC<p>
-----------------
Output would be
-----------------
ABC<p>

-----------------

it will only remove the first para

para tag,Not for the second para

tag and all text in between would be same.

I want to mention here that i am looking for

<p>ABC<p> 

not for

<p>ABC</p>

Its for specific text file having irregular

tags

Example:

i have big xhtml file like...

<p>scet</p>
<p>sunny </p>
<p>             <!--this tag is to be removed -->
<p>              <!--this tag is to be removed -->
<p>mark</p>
<p>Thomas </p>

its a complete XHTML file.having body head etc tags Only problem here is extra tags i am expecting output like this

<p>scet</p>
<p>sunny </p>

<p>mark</p>
<p>Thomas </p>

解决方案

This will work, take html document in string xhtml

 public static class XHTMLCleanerUpperThingy
    {
        private const string p = "<p>";
        private const string closingp = "</p>";

    public static string CleanUpXHTML(string xhtml)
    {
        StringBuilder builder = new StringBuilder(xhtml);
        for (int idx = 0; idx < xhtml.Length; idx++)
        {
            int current;
            if ((current = xhtml.IndexOf(p, idx)) != -1)
            {
                int idxofnext = xhtml.IndexOf(p, current + p.Length);
                int idxofclose = xhtml.IndexOf(closingp, current);

                // if there is a next <p> tag
                if (idxofnext > 0)
                {
                    // if the next closing tag is farther than the next <p> tag
                    if (idxofnext < idxofclose)
                    {
                        for (int j = 0; j < p.Length; j++)
                        {
                            builder[current + j] = ' ';
                        }
                    }
                }
                // if there is not a final closing tag
                else if (idxofclose < 0)
                {
                    for (int j = 0; j < p.Length; j++)
                    {
                        builder[current + j] = ' ';
                    }
                }
            }
        }

        return builder.ToString();
    }
}
