C#删除第一个环绕div [英] C# remove first wraping div

问题描述

我正在尝试删除报告字符串中出现的第一个.

I'm trying to remove the first that appears in my reporting string.

Actual result:
<div><div><p>This is a test</p><ul><li>a</li><li>b</li><li>c</li></ul></div></div>

Expected result
<div><p>This is a test</p><ul><li>a</li><li>b</li><li>c</li></ul></div>

我一直在尝试将整个字符串转换为数组，这样我就可以删除它的第一个和最后一个元素，但是由于没有逗号或空格，我很难拆分它.

I've been trying to convert the whole string into an array so I can just remove the first and last element of it, but I'm having a hard time splitting it since there are no commas or spaces.

我如何进行?要删除的HTML将始终是多余的div

How can I procede? the HTML to be eliminated will always be that extra div

推荐答案

此方法将考虑您在第一个div中具有属性的情况(IE < div class ='bla'>< div>文本</div></div> ).为了完整起见并避免未处理的异常，您应该检查边缘情况(例如空字符串，格式错误的html ...)

This method will take into account the case scenario where you have an attribute in the first div (I.E. <div class='bla'> <div> text </div> </div>). For completeness and to avoid unhandled exception you should check for edge cases (such as empty strings, malformed html...)

    public string InnerDiv(string html)
    {
        var start_idx = html.IndexOf(">", html.IndexOf("<div", StringComparison.InvariantCulture), StringComparison.InvariantCulture) + 1;
        var last_idx = html.LastIndexOf("</div>", StringComparison.InvariantCulture);
        return html.Substring(start_idx, last_idx - start_idx);
    }
