Javascript RegExp匹配< a>之间的文本标签 [英] Javascript RegExp match text between <a> tags

问题描述

我需要匹配一个javascript RegExp字符串：bimbo999来自这个标签：< a href =/ game.php？village = 828& amp; screen = info_player& amp; id = 29956> bimbo999< / a>

I need to match with a javascript RegExp the string: bimbo999 from this a tag: <a href="/game.php?village=828&amp;screen=info_player&amp;id=29956" >bimbo999</a>

URL变量（村庄和身份证）的数字每次都在变化所以我必须用RegExp以某种方式匹配数字。

The numbers from URL vars (village and id) are changing every time so I have to match the numbers somehow with RegExp.

                    <tr><td>Sent</td><td >Oct 22, 2011  17:00:31</td></tr>
                                <tr>
                        <td colspan="2" valign="top" height="160" style="border: solid 1px black; padding: 4px;">
                            <table width="100%">
    <tr><th width="60">Supported player:</th><th>
    <a href="/game.php?village=828&amp;screen=info_player&amp;id=29956" >bimbo999</a></th></tr>
    <tr><td>Village:</td><td><a href="/game.php?village=828&amp;screen=info_village&amp;id=848" >bimbo999s village (515|520) K55</a></td></tr>
    <tr><td>Origin of the troops:</td><td><a href="/game.php?village=828&amp;screen=info_village&amp;id=828" >KaLa I (514|520) K55</a></td></tr>
    </table><br />

    <h4>Units:</h4>
    <table class="vis">

我试过这个：

var match = h.match(/Supported player:</th>(.*)<\/a><\/th></i);

但不起作用。你们能帮助我吗？

but is not working. Can you guys, help me?

推荐答案

试试这个：

/<a[^>]*>([\s\S]*?)<\/a>/

• < a [^>] *> 匹配开头 a 标签


• （[\\\ S] *？）匹配结束标记前的任何字符，尽可能少


• < \ / a> 匹配结束标记


• <a[^>]*> matches the opening a tag
• ([\s\S]*?) matches any characters before the closing tag, as few as possible
• <\/a> matches the closing tag

（[\\\\ S] *？）将标记之间的文本捕获为从 exec 或匹配调用返回的数组中的参数1。

The ([\s\S]*?) captures the text between the tags as argument 1 in the array returned from an exec or match call.

这对在 a 元素中找到文本非常有用，它不是非常安全或可靠，但是如果你有一个很大的链接页面而你只需要他们的文本，那就可以了。

This is really only good for finding text within a elements, it's not incredibly safe or reliable, but if you've got a big page of links and you just need their text, this will do it.

如果没有RegExp，更安全的方法是：

A much safer way to do this without RegExp would be:

function getAnchorTexts(htmlStr) {
    var div,
        anchors,
        i,
        texts;
    div = document.createElement('div');
    div.innerHTML = htmlStr;
    anchors = div.getElementsByTagName('a');
    texts = [];
    for (i = 0; i < anchors.length; i += 1) {
        texts.push(anchors[i].text);
    }
    return texts;
}
