Question

我有这个HTML：

    <a id='topnavbtn_tutorials' href='javascript:void(0);' onclick='w3_open_nav("tutorials")' title='Tutorials'>TUTORIALS <i class='fa fa-caret-down'></i><i class='fa fa-caret-up' style='display:none'></i></a><a id='topnavbtn_references' href='javascript:void(0);' onclick='w3_open_nav("references")' title='References'>REFERENCES <i class='fa fa-caret-down'></i><i class='fa fa-caret-up' style='display:none'></i></a><a id='topnavbtn_examples' href='javascript:void(0);' onclick='w3_open_nav("examples")' title='Examples'>EXAMPLES <i class='fa fa-caret-down'></i><i class='fa fa-caret-up' style='display:none'></i></a><a href='/forum/default.asp'>FORUM</a></div></div>
<div id='nav_tutorials' class='w3-dropnav w3-light-grey w3-card-2 w3-center'></div>
<div id='nav_references' class='w3-dropnav w3-light-grey w3-card-2 w3-center'></div>
<div id='nav_examples' class='w3-dropnav w3-light-grey w3-card-2 w3-center'></div>
<div id='nav_translate' class='w3-dropnav w3-light-grey w3-card-2 w3-center'></div>
<div id='nav_search' class='w3-dropnav w3-light-grey w3-card-2 w3-center'></div></div>
<div class='w3-row w3-light-grey' id='belowtopnav'>
<div class='w3-col w3-slim' id='leftmenu'>
<div id='leftmenuinner'>
<div class='w3-light-grey' id='leftmenuinnerinner'>
<a href='javascript:void(0)' onclick='close_menu()' class='w3-closebtn w3-hide-large w3-large' style='padding:3px 12px;'>&times;</a>
<h2 class="left"><span class="left_h2">Colors</span> Tutorial</h2>
<a target="_top" href="default.asp">Colors HOME</a>
<a target="_top" href="colors_names.asp">Color Names</a>

我已经写了这个正则表达式：

<a .*?href=("|').*?\.asp("|').*?>.*?<\/a>

我只需匹配：

1

<a href='/forum/default.asp'>FORUM</a>

2

<a target="_top" href="default.asp">Colors HOME</a>

3

  <a target="_top" href="colors_names.asp">Color Names</a>

以下是当前正则表达式的匹配（第一个结果不好）：

1

<a id='topnavbtn_tutorials' href='javascript:void(0);' onclick='w3_open_nav("tutorials")' title='Tutorials'>TUTORIALS <i class='fa fa-caret-down'></i><i class='fa fa-caret-up' style='display:none'></i></a><a id='topnavbtn_references' href='javascript:void(0);' onclick='w3_open_nav("references")' title='References'>REFERENCES <i class='fa fa-caret-down'></i><i class='fa fa-caret-up' style='display:none'></i></a><a id='topnavbtn_examples' href='javascript:void(0);' onclick='w3_open_nav("examples")' title='Examples'>EXAMPLES <i class='fa fa-caret-down'></i><i class='fa fa-caret-up' style='display:none'></i></a><a href='/forum/default.asp'>FORUM</a>

2

<a target="_top" href="default.asp">Colors HOME</a>

3

  <a target="_top" href="colors_names.asp">Color Names</a>

请修改我现有的正则表达式。

Answer 1

这个正则表达式似乎工作正常：

// Authentication module.
var auth = require('http-auth');
var basic = auth.basic({
    realm: "Simon Area.",
    file: __dirname + "/../data/users.htpasswd" // gevorg:gpass, Sarah:testpass ...
});

// Creating new HTTP server.
http.createServer(basic, function(req, res) {
    res.end("Welcome to private area - " + req.user + "!");
}).listen(1337);

Working example

没有那些的所有html锚标记都包含特定的字符串
