c# - 如何解析两个元素之间的单词并将其提取出来

Question

例子

<reference>employee</reference>

<data>123</data>

如何使用 C# 进行解析以便我应该将 employee 和 123 作为输出

Answer 1

你可以用它制作一个 XML 文档，并解析它:

string info = "<reference>employee</reference><data>123</data>";

XmlDocument doc = new XmlDocument();
doc.LoadXml("<root>" + info + "</root>");
string reference = doc.DocumentElement.FirstChild.InnerText;
string data = doc.DocumentElement.FirstChild.NextSibling.InnerText;

另一种选择是使用正则表达式来解析字符串:

string info = "<reference>employee</reference><data>123</data>";

MatchCollection m = Regex.Matches(info, "<.+?>(.+?)</.+?>");
string reference = m[0].Groups[1].Value;
string data = m[1].Groups[1].Value;

或者简单的字符串操作:

string info = "<reference>employee</reference><data>123</data>";

int start = info.IndexOf("<reference>") + 11;
string reference = info.Substring(start, info.IndexOf('<', start) - start);
start = info.IndexOf("<data>") + 6;
string data = info.Substring(start, info.IndexOf('<', start) - start);
