Regx 匹配表达式通过排除 html 标签来查找
[英]Regx Match Expression to find by exlcuding html tags
问题描述
var TextToFind = "The Term is Fixed";
var TexToSearch = "<head>The</head> Term is Fixed";
The expression used now is (?mi)\\bThe Term is Fixed\\b .
现在使用的表达式是(?mi)\\bThe Term is Fixed\\b 。
How can we modify this existing expression pattern to find the text with tags?我们如何修改这个现有的表达模式来找到带有标签的文本？

You can do this as follows您可以按如下方式执行此操作
string str = "< head > The </ head > Term is Fixed";
string textWithoutTags = Regex.Replace(str, "<[^>]*>", string.Empty);

To match all the substrings you have with tags or whitespace between the words, you may dynamically construct a regex like要匹配所有带有标签或单词之间的空格的子字符串，您可以动态构建一个正则表达式，如
The(?>\s*<[^>]*>\s*|\s+)Term(?>\s*<[^>]*>\s*|\s+)is(?>\s*<[^>]*>\s*|\s+)Fixed
where each space is replaced with (?>\\s*<[^>]*>\\s*|\\s+) pattern that matches either其中每个空格都替换为(?>\\s*<[^>]*>\\s*|\\s+)匹配的模式
\\s*<[^>]*>\\s*-<, then 0 or more chars other than<and>and then>, enclosed with 0 or more whitespaces\\s*<[^>]*>\\s*-<，然后是除<和>之外的 0 个或多个字符，然后是>，用 0 个或多个空格括起来|- or- 或者\\s+- 1 or more whitespaces.\\s+- 1 个或多个空格。
See the regex demo查看正则表达式演示
var TextToFind = "The Term is Fixed";
var TexToSearch = "<head>The</head> Term is Fixed\n<head>The</head> Term <span>is</span> Fixed";
var regex = string.Join(@"(?>\s*<[^>]*>\s*|\s+)", TextToFind.Split());
var result = Regex.Matches(TexToSearch, regex).Cast<Match>().Select(x => x.Value);
foreach (var s in result)
Console.WriteLine(s);
Output:输出：
The</head> Term is Fixed
The</head> Term <span>is</span> Fixed
