C＃：正则表达式匹配最近

Question

<table class="listProvision" class="itable">
    <tr>
        <td class="whatever">some infos</td>
        <td>some more infos</td>
        <td>13908402</td>
        <td>hello world</td>
    </tr>
    <tr>
        <td class="whatever">some infos</td>
        <td>some more infos</td>
        <td id="num">13908402</td>
        <td>hello world</td>
    </tr>
</table>

Given the above sample HTML, how can I properly parse all existences of <tr>...</tr> between the table with class listProvision ?

I tried: <table.*?listProvision.*?>(?:.*?<tr.*?>(.*?)</tr>)+.*?</table> , but I can't figure out what's wrong. There is never going to be any complicated html pulled into this regex so don't worry about that.

Answer 1

Here is sample how you can parse html string with Html Agility Pack

HtmlDocument doc = new HtmlDocument();
doc.LoadHtml(html);

var rows = doc.DocumentNode
              .SelectNodes("//table[@class='listProvision']/tr");

Then you can use HtmlNode.InnerHtml property to get all data between <tr>...</tr> tags.

1) Use RegexOptions.Singleline to make dot match newline. (your regex works already, I got it work here with just the single-line flag)

2) access match.Groups["yourNamedCaptureGroup"].Captures for your captures.
