XPath：获取子节点包含属性的节点如何在c＃中选择具有和属性且父节点具有另一个属性的节点

Question

我有一个像XML

<Validation>
    <Presentation>
        <Slide Tag = "Pippo">
            <Shape Name = "Pluto"/>
        </Slide>
        <Shape Name = "Pluto"/>
    </Presentation>
</Validation>

我如何改善此C＃代码段

 String xPath = string.Format("/Validation/Presentation/Shape[@Name='{0}'][1]", "Pluto");
 XmlNode node = doc.DocumentElement.SelectSingleNode(xPath);

仅获得属性名称为“ Pluto”且其父级具有标签为“ Pippo”的形状节点？

Answer 1

您可以使用以下Xpath字符串获取此节点：

string xPath = string.Format("//*[@Tag='{0}']/Shape[@Name='{1}']", "Pippo","Pluto");
XmlNode node = doc.DocumentElement.SelectSingleNode(xPath);
