HTML敏捷包删除儿童 [英] html agility pack remove children
问题描述
我有困难，试图删除一个div与特定的ID，并使用HTML敏捷包它的孩子。 。我相信我只是缺少一个配置选项，但其周五和我挣扎
简化的HTML运行：
< HTML>< HEAD>< /头><身体GT;< DIV ID ='包装'>< DIV ID ='functionBar >< DIV ID ='搜索'>< / DIV>< / DIV>< / DIV>< /身体GT;< / HTML>
这是据我已经得到。由敏捷包抛出的错误显示它无法找到一个div结构：
< DIV ID ='functionBar'>< ; / DIV>
下面是到目前为止的代码
$ B $（从....＃1所） b HtmlAgilityPack.HtmlDocument HTMLDOC =新HtmlAgilityPack.HtmlDocument（）;
//有多种选择，根据需要设置
//htmlDoc.OptionFixNestedTags = TRUE;
//文件路径是包含HTML
htmlDoc.LoadHtml（HTML）的文件的路径;
字符串输出=的String.Empty;
// ParseErrors是包含从Load声明
如果（htmlDoc.ParseErrors = NULL&放！;&安培; htmlDoc.ParseErrors.Count大于0）的任何错误一个ArrayList
{
//处理任何解析错误所需
}
，否则
{
如果（htmlDoc.DocumentNode！= NULL）
{
HtmlAgilityPack.HtmlNode bodyNode = htmlDoc.DocumentNode.SelectSingleNode（//体）;
如果（！bodyNode = NULL）
{
HtmlAgilityPack.HtmlNode functionBarNode = bodyNode.SelectSingleNode（// DIV [@ ID ='functionBar']）;
bodyNode.RemoveChild（functionBarNode，FALSE）;
输出= bodyNode.InnerHtml;
}
}
}
bodyNode.RemoveChild（functionBarNode，FALSE）;
但functionBarNode不是一个孩子bodyNode。
如何
functionBarNode.ParentNode.RemoveChild（functionBarNode，FALSE）？ （而忘记寻找bodyNode位。）I'm having difficulty trying to remove a div with a particular ID, and its children using the HTML Agility pack. I am sure I'm just missing a config option, but its Friday and I'm struggling.
The simplified HTML runs:
<html><head></head><body><div id='wrapper'><div id='functionBar'><div id='search'></div></div></div></body></html>This is as far as I have got. The error thrown by the agility pack shows it cannot find a div structure:
<div id='functionBar'></div>Here's the code so far (taken from Stackoverflow....)
HtmlAgilityPack.HtmlDocument htmlDoc = new HtmlAgilityPack.HtmlDocument(); // There are various options, set as needed //htmlDoc.OptionFixNestedTags = true; // filePath is a path to a file containing the html htmlDoc.LoadHtml(Html); string output = string.Empty; // ParseErrors is an ArrayList containing any errors from the Load statement if (htmlDoc.ParseErrors != null && htmlDoc.ParseErrors.Count > 0) { // Handle any parse errors as required } else { if (htmlDoc.DocumentNode != null) { HtmlAgilityPack.HtmlNode bodyNode = htmlDoc.DocumentNode.SelectSingleNode("//body"); if (bodyNode != null) { HtmlAgilityPack.HtmlNode functionBarNode = bodyNode.SelectSingleNode ("//div[@id='functionBar']"); bodyNode.RemoveChild(functionBarNode,false); output = bodyNode.InnerHtml; } } }
解决方案bodyNode.RemoveChild(functionBarNode,false);
But functionBarNode is not a child of bodyNode.
How about
functionBarNode.ParentNode.RemoveChild(functionBarNode, false)? (And forget the bit about finding bodyNode.)这篇关于HTML敏捷包删除儿童的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
