正则验证ip

用python爬获取这样一条数据：

<td class="ip" id="ip"><p style="display: none;"></p><span></span><p style="display: none;">4</p><span></span><p style="display: none;">2</p><span>2</span><div style="display:inline-block;">2</div><span style="display:inline-block;">2</span><div style="display:inline-block;">.9</div><p style="display: none;">4</p><span>4</span><span style="display:inline-block;">.1</span><span style="display:inline-block;"></span><div style="display:inline-block;">49</div><span style="display:inline-block;">.</span><div style="display:inline-block;">13</div><span style="display:inline-block;"></span><span style="display:inline-block;"></span><span style="display:inline-block;"></span><p style="display: none;">4</p><span>4</span>:<span class="port GEGE">8976</span></td>

　　

格式话是这样子的：

<td class="ip" id="ip"><p style="display: none;"></p><span></span>
    <p style="display: none;">4</p><span></span>
    <p style="display: none;">2</p><span>2</span>
    <div style="display:inline-block;">2</div>
    <span style="display:inline-block;">2</span>
    <div style="display:inline-block;">.9</div>
    <p style="display: none;">4</p><span>4</span><span style="display:inline-block;">.1</span><span
            style="display:inline-block;"></span>
    <div style="display:inline-block;">49</div>
    <span style="display:inline-block;">.</span>
    <div style="display:inline-block;">13</div>
    <span style="display:inline-block;"></span><span style="display:inline-block;"></span><span
            style="display:inline-block;"></span>
    <p style="display: none;">4</p><span>4</span>:<span class="port GEGE">8976</span></td>

　　

通过正则获取的数据是样子：

222.92.149.134.8976

　

代码如下：

/*
    *  \<span\>\d{1,5}\<\/span\>
    *  \<span\sstyle\=\"display\:inline\-block\;\"\>(\.|\.\d{1,}|\d{1,})\<\/span\>

    var str = '<td class="ip" id="ip"><p style="display: none;"></p><span></span><p style="display: none;">4</p><span></span><p style="display: none;">2</p><span>2</span><div style="display:inline-block;">2</div><span style="display:inline-block;">2</span><div style="display:inline-block;">.9</div><p style="display: none;">4</p><span>4</span><span style="display:inline-block;">.1</span><span style="display:inline-block;"></span><div style="display:inline-block;">49</div><span style="display:inline-block;">.</span><div style="display:inline-block;">13</div><span style="display:inline-block;"></span><span style="display:inline-block;"></span><span style="display:inline-block;"></span><p style="display: none;">4</p><span>4</span>:<span class="port GEGE">8976</span></td>'
    pattern = /(\<span\>\d{1,4}\<\/span\>)|(\<span\sstyle\=\"display\:inline\-block\;\"\>(\.|\.\d{1,}|\d{1,})\<\/span\>)|(\<div\sstyle\=\"display\:inline\-block\;\"\>(\.|\.\d{1,}|\d{1,})\<\/div\>)|(\:\<span\sclass\=\"port\sGEGE\"\>\d{0,5}\<\/span\>)/ig;
    var result = str.match(pattern);
    console.log(result);
    var numArr = [];
    for(var i = 0; i < result.length; i++){
        var flag = result[i].match(/(^\:)|(\.{0,1}\d{1,5})|\./ig);
        if(flag){
            var sigle = flag;
            numArr = numArr.concat(sigle);
        }
    }
    console.log(numArr.join(''));
