Are the angle brackets (< or >) special in a regular expression?
提问by Mike Depies
I am trying to get a regex expression to accept < and > as my outside delimiters to grab all the content in between them.
我试图让正则表达式接受 < 和 > 作为我的外部分隔符来获取它们之间的所有内容。
so content like such
如此内容
< tfdsfa >
should be grabbed.
应该被抓住。
Do I have to escape the < and > characters or something?
我是否必须转义 < 和 > 字符或其他什么？
Regex generated by my script:
我的脚本生成的正则表达式：
/<[^(>)]*>/g
Code from file:
来自文件的代码：
data.method.highlight = function() {
var x = data.syntax,
text = data.$.span.html();
for (var i=0, len = x.length; i < len; i++) {
var rx;
if (x[i].range) {
rx = new RegExp(x[i].tag[0] + "[^(" + x[i].tag[1] + ")]*" + x[i].tag[1], "g");
console.log(rx);
}
else {
var temprx = x[i].tag[0];
for (var z = 1; z < x[i].tag.length; z++) {
temprx += "|" + x[i].tag[z];
}
rx = new RegExp(temprx, "g");
}
text = text.replace(rx,function (match) {
console.log("looping - range");
return '<span class="' + x[i].class.default + '">' + match + '</span>';
});
data.$.span.html(text);
}
};

Neither <nor >are metacharacters inside a regular expression.
正则表达式中既不是元字符，<也不>是元字符。
This works for me:
这对我有用：
'<foo> and <bar>'.match(/<[^>]*>/g); // ["<foo>", "<bar>"]

May be you have problem because you trying to insert result into HTML and browser 'thinks' that it is a not valid HTML tag, like <blablabla>.
可能是因为您尝试将结果插入 HTML 而浏览器“认为”它是无效的 HTML 标记，例如<blablabla>.
