推荐答案

请参阅我对该问题的评论。问题是：如果您的HTML与使用脚本的地方相同，则会立即对其进行解析，因此您只能使用Javascript操作DOM树。

基于此，答案33显示了您感兴趣的技巧可用于解析任何HTML字符串： http://stackoverflow.com/questions/10585029/ parse-a-html-string-with-js [ ^ ]。



此外，jQuery已经有一个明确的HTML解析器： http://api.jquery.com/jquery.parsehtml [ ^ ]。



或者，你可以找到一些其他可用的HTML解析器：http://bit.ly/1hmkFs2 [ ^ ]。



例如： https ：//www.npmjs.org/package/htmlparser [ ^ ]。



此外，如果您确定HTML是用格式良好的XML文档编写的，您可以将其解析为XML：http://www.w3schools.com/xml/xml_parser.asp [ ^ ]。

Please see my comment to the question. The thing is: if your HTML is the same where your script is used, it is parsed immediately, so you only manipulate DOM tree with Javascript.
Based on that, the answer 33 shows interesting technique which you can use to parse any HTML string: http://stackoverflow.com/questions/10585029/parse-a-html-string-with-js[^].

Also, jQuery already has an explicit HTML parser: http://api.jquery.com/jquery.parsehtml[^].

Alternatively, you can find some other available HTML parser: http://bit.ly/1hmkFs2[^].

For example: https://www.npmjs.org/package/htmlparser[^].

Besides, if you are sure that the HTML is written as well-formed XML document, you can parse it as XML: http://www.w3schools.com/xml/xml_parser.asp[^].

试试这个。您必须稍微更改代码以删除时间：/ Where：/ br在最终文本中。但现在你知道了这个想法:)

Try this. You have to change the code little bit to remove When:/Where:/br in the final text. But now you know the idea :)

function search() {
        var searchValue1 = "When: ";
        var searchValue2 = "Where: ";
        var searchValue3 = "Temperature: ";

        var elements = document.querySelectorAll('.sdi-quickhits');
        var index1 = elements[0].innerHTML.indexOf(searchValue1);
        var index2 = elements[0].innerHTML.indexOf(searchValue2);
        var index3 = elements[0].innerHTML.indexOf(searchValue3);

        if (index1 > -1 && index2 > -1 && index3 > -1) {
            var res1 = elements[0].innerHTML.substring(index1, index2);
            var res2 = elements[0].innerHTML.substring(index2, index3);
            alert(res1);
            alert(res2);
        }
    }
