需要删除字符串中的xml节点并保留文本 [英] need to remove xml nodes in a string and leave the text

问题描述

我有一个字符串，它是 xml 的一部分.

a<b>b</b>c<i>d</i>e<b>f</b>g

问题是我想从字符串中提取不在任何标签内的部分.所以我需要从这个字符串中提取字符串aceg"并留下字符bdf"这怎么办?

这是 xml 的一部分让我们假设它

abcdefg

现在它是一个有效的 xml :)

解决方案

该字符串不是有效的 XML.

但是，假设您有一个有效的 XML 字符串，那么您可以执行以下操作:

class 程序{static void Main(string[] args){字符串内容 = string.Empty;XmlDocument 文档 = 新 XmlDocument();document.LoadXml("<outer>a<b>b</b>c<i>d</i>e<b>f</b>g</outer>");foreach(document.DocumentElement.ChildNodes 中的 XmlNode 子节点){if (child.NodeType == XmlNodeType.Element){内容 += child.InnerText;}}Console.WriteLine(内容);Console.ReadKey();}}

这将打印出字符串bdf"

i have the string which is a part of an xml.

a<b>b</b>c<i>d</i>e<b>f</b>g

the problem is that i want to extract from the string the parts that are not inside any tags. so i need to extract the string"aceg" from this string and leave the characters "bdf" how can this be done?

Edit: this was a part of an xml let asume its

<div>a<b>b</b>c<i>d</i>e<b>f</b>g</div>

now its a valid xml :)

解决方案

That string is not valid XML.

However, assuming you had a valid XML string, then you could do something like this:

class Program
{
    static void Main(string[] args)
    {
        string contents = string.Empty;

        XmlDocument document = new XmlDocument();
        document.LoadXml("<outer>a<b>b</b>c<i>d</i>e<b>f</b>g</outer>");

        foreach(XmlNode child in document.DocumentElement.ChildNodes)
        {
            if (child.NodeType == XmlNodeType.Element)
            {
                contents += child.InnerText;
            }
        }

        Console.WriteLine(contents);

        Console.ReadKey();
    }
}

This will print out the string "bdf"
