如何使用XPATH从其键中选择xmlnode

Question

Here is my XML file

 <Drive>
    <Data0 Key="1" Name="AA" />
    <Data1 Key="2" Name="BB" />
    <Data2 Key="4" Name="CC" />
    <Data3 Key="10" Name="WW" />
    <Data4 Key="11" Name="WE" />
    <Data5 Key="12" Name="VW" />
    </Drive>

I want to select all nodes where their [Key] start with "1" using C# and XML XPATH

I tried this:

XmlNodeList FKNodes = node.SelectNodes("*/* [@Key like '1*']")

Answer 1

您可以使用*选择任何名称的元素，并使用starts-with()函数部分匹配Key属性值：

XmlNodeList FKNodes = node.SelectNodes("//*[starts-with(@Key, '1')]")
