验证.NET中的XPath [英] Verify an XPath in .NET

问题描述

如何验证给定的xpath字符串在C#/.NET中有效?

How can I verify a given xpath string is valid in C#/.NET?

我不确定仅运行XPath并捕获异常是否是有效的解决方案(暂时将胆汁放在喉咙旁)-如果明天遇到其他未测试的输入怎么办?

I'm not sure just running the XPath and catching exceptions is a valid solution (putting aside the bile in my throat for a moment) - what if tomorrow I run into some other input I haven't tested against?

您尝试从中构建一个 XPathExpression 并捕获异常.

You try to build an XPathExpression from it and catch the exception.

try 
{
    XPathExpression.Compile(xPathString);
}
catch (XPathException ex)
{
    MessageBox.Show("XPath syntax error: " + ex.Message);
}
