我遇到了以下问题。我有一个像这样的xml文件:
<Source Name ="ClassificationManager">
<Table Name ="PositiveRegex">
<Row>
<Field Name="RegexPattern">^.*$</Field>
<Field Name="Fraction">5.1</Field>
<Field Name="ClassificationTypeNumber">1</Field>
</Row>
<Row>
<Field Name="RegexPattern">^.*$</Field>
<Field Name="Fraction">0.1</Field>
<Field Name="ClassificationTypeNumber">2</Field>
</Row>
</Table>
<Table Name ="NegativeRegex">
<Row>
<Field Name="RegexPattern">^.*$</Field>
<Field Name="ClassificationTypeNumber">1</Field>
</Row>
<Row>
<Field Name="RegexPattern">^.*$</Field>
<Field Name="ClassificationTypeNumber">2</Field>
</Row>
</Table>
</Source>
和C#程序:
XDocument doc = XDocument.Load(@"C:\Repository.xml");
XElement element = doc.XPathSelectElement(@"//Source[@Name='ClassificationManager']/Table[@Name='NegativeRegex']");
foreach (var xmlRow in element.Elements("Row"))
{
Console.WriteLine(xmlRow.XPathSelectElement(@"//Field[@Name='ClassificationTypeNumber']").Value);
}
输出为1, 1
但不是我想要的1, 2
。怎么了?如何修改C#代码以获得我需要的东西?
谢谢你的帮助!
答案 0 :(得分:0)
Console.WriteLine(xmlRow.XPathSelectElement(@"//Field[@Name='ClassificationTypeNumber']").Value);
必须是:
Console.WriteLine(xmlRow.XPathSelectElement(@"/Field[@Name='ClassificationTypeNumber']").Value);
//
从根目录中选择,而不是当前元素。
