使用C#正则表达式将span字符替换为span标记. [英] Replace speacial characters with span tag using c# regular expressions.

问题描述

我们有一个测试，例如这是一个错误(正在解决)?& @#17066.".
用以下逻辑修改测试后:

We have a test like "This is a bug (solveing) ? & @ # 17066.".

After we modify the test with below logic :

// replace <br /> tags with new line characters
            string replaceContent = Regex.Replace(contentText, @"", "\n");

            // add full stop to inner text of an element, if it needs one, to separate from next word when tags removed
            replaceContent = Regex.Replace(replaceContent, @"\w(?=)", @"$0\.");

            // remove all tags and leading and trailing space          
            replaceContent = Regex.Replace(replaceContent, "<.*?>", string.Empty).Trim();
            CommonMethods.WordMatchCollection = CommonMethods.WordRegularExpression.Matches(replaceContent);

            // match words which are not in tags
            string pattern = @"(?<!<[^>]*?)\b(\w+|\w+['-]\w+)\b(?![^<]*?>)";
            string replacement = "<span>$0</span>";

            // surround words in text with <span> tags
            contentText = Regex.Replace(contentText, pattern, replacement);

            return contentText;</span>

格式化的测试如下:-

这 是 a bug (正在解决) ? & amp ; @# 17066 .




我们还要为#，$，@等特殊字符添加Span标签.
我们该怎么做.

The formated test is as follows:-

This is a bug (solveing) ? & @ # 17066.




We want to add Span tags for Speacial character like #, $, @ etc also.
How we can do this.

Thanks in Advanced.

推荐答案

0 \.")； // 删除所有标签以及前后空格 replaceContent = Regex.Replace(replaceContent，" ，字符串 .Empty).Trim(); CommonMethods.WordMatchCollection = CommonMethods.WordRegularExpression.Matches(replaceContent); // 匹配不在标签中的单词 字符串 pattern = @" ; 字符串替换= "

0\."); // remove all tags and leading and trailing space replaceContent = Regex.Replace(replaceContent, "<.*?>", string.Empty).Trim(); CommonMethods.WordMatchCollection = CommonMethods.WordRegularExpression.Matches(replaceContent); // match words which are not in tags string pattern = @"(?<!<[^>]*?)\b(\w+|\w+['-]\w+)\b(?![^<]*?>)"; string replacement = "<span>

0</span>"; // 用< span>包围文本中的单词标签 contentText = Regex.Replace(contentText，pattern，replacement); 返回 contentText； </ span >

0</span>"; // surround words in text with <span> tags contentText = Regex.Replace(contentText, pattern, replacement); return contentText;</span>

格式化的测试如下:-

这 是 a bug (正在解决) ? & amp ; @# 17066 .




我们要为#这样的特殊字符添加Span标签，

The formated test is as follows:-

This is a bug (solveing) ? &amp; @ # 17066.




We want to add Span tags for Speacial character like #,

，@等.
我们该怎么做.
