如何使用Linq to XML Query搜索节点？

Question

在xml doc下面

    <Root>
        <Global>
        </Global>
        <local>
            <section name="A">
                <subsection name="A">
                    <innersection name="A">
                        <Property1>
                        </Property1>
                    </innersection>
                    <innersection name="B">
                        <Property1>
                        </Property1>
                    </innersection>
                </subsection>
                <subsection name="B">
                    <innersection name="A">
                        <Property1>
                        </Property1>
                    </innersection>
                    <innersection name="B">
                        <Property1>
                        </Property1>
                    </innersection>
                </subsection>
            </section>
            <section name="B">
                <subsection name="A">
                    <innersection name="A">
                        <Property1>
                        </Property1>
                    </innersection>
                    <innersection name="B">
                        <Property1>
                        </Property1>
                    </innersection>
                </subsection>
                <subsection name="B">
                    <innersection name="A">
                        <Property1>
                        </Property1>
                    </innersection>
                    <innersection name="B">
                        <Property1>
                        </Property1>
                    </innersection>
                </subsection>
            </section>
        </local>
    </Root>

现在我想要一个使用linq到xml的单个查询中的section1,其section name ="B"和subsection name ="B"以及innersection name ="B".

Answer 1

这是我的选择,替代Jon的,假设Property1只在一个innersection中出现,你只需要那个:

var Property1 = doc.Root.Elements("local").Elements("section")
    .Where(x => x.Attribute("name") == "B").Elements("subsection")
    .Where(x => x.Attribute("name") == "B").Elements("innersection")
    .Where(x => x.Attribute("name") == "B").Element("Property1");
