javascript - 使用正则表达式删除特殊字符

Question

伙计们。我有一个包含很多特殊字符的特定字符串，我需要将其删除。

这是字符串:

let str = 'The start tag must have a matching end tag.  An explicit end tag can be provided by adding </cfscript>.If the body of the tag is empty, you can use the shortcut <cfscript .../>.<p>The CFML compiler was processing:<ul><li>A cfscript tag beginning on line 90, column 10.<li>A cfscript tag beginning on line 90, column 10.</ul>'

这是我的正则表达式，它不起作用:var regex = str.replace(/<|>|\/|\/ul|\/li|ul&|li&/g,'')

任何帮助都会很棒!谢谢

Answer 1

您正在尝试去除转义的 HTML 标签(< 是 <；并且 > 是 >)，以及它们之间的所有内容(参见 regex101 ) :

const str = 'The start tag must have a matching end tag.  An explicit end tag can be provided by adding </cfscript>.If the body of the tag is empty, you can use the shortcut <cfscript .../>.<p>The CFML compiler was processing:<ul><li>A cfscript tag beginning on line 90, column 10.<li>A cfscript tag beginning on line 90, column 10.</ul>'

const result = str.replace(/<.+?>/g,'')

console.log(result)
