xml文档下方

    <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>

现在我想要使用 linq to xml 在一个查询中使用 property1，其部分名称为“B”，子部分名称为“B”，内部部分名称为“B”。

Answer 1

这是我的看法，替代 Jon 的看法，假设 Property1 仅在内部部分出现一次，而您只需要那个:

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");
