这是我拥有的 XML 文件的一部分，我需要检索在以下位置找到的信息:

                            <choicesConfig>
                                <clear />
                                <element text="Unspecified" value="Unspecified" enabled="False" selected="False" />
                                <element text="Implementation" value="Implementation" enabled="False" selected="False" />
                                <element text="Sales" value="Sales" enabled="False" selected="False" />
                                <element text="Support" value="Support" enabled="False" selected="False" />
                                <element text="Technical Sales" value="Technical Sales" enabled="False" selected="False" />
                                <element text="Validation" value="Validation" enabled="False" selected="False" />
                            </choicesConfig>

我尝试过观看视频和阅读 msdn，但我无法专门访问该区域。有没有什么快速的方法可以通过指定 dataFieldName="MCRole"或更简单的方法来获取这个区域？

我只对每个 <element text = "x" 的文本值感兴趣

提前谢谢你。

Answer 1

加载到 XDocument ，搜索名为“element”的元素，然后获取名为“text”的属性:

        var doc = XDocument.Parse(xml);
        var texts = doc.Descendants(doc.Root.Name.Namespace + "element").SelectMany(el => el.Attributes(doc.Root.Name.Namespace + "text")).ToList();

如果你只想要 "choicesConfig" 下的元素，你可以这样做:

        var texts = doc.Descendants(doc.Root.Name.Namespace + "choicesConfig").Descendants(doc.Root.Name.Namespace + "element").SelectMany(el => el.Attributes(doc.Root.Name.Namespace + "text")).ToList();

更新

对于更复杂的查询，使用 XPathSelectElements正如其他人所建议的那样不是一个坏主意。因此，如果你想挑选出名为“ViewFrontendCreate”的 View 并将所有文本累积在它们的“choicesConfig”下，你可以这样做:

        var viewName = "ViewFrontendCreate";
        var views = doc.Root.XPathSelectElements(string.Format("/contentViewConfig/contentViewControls/contentViewControl/views/view[@viewName='{0}']", viewName));
        var texts = views.Descendants("choicesConfig").Descendants("element").SelectMany(el => el.Attributes("text")).ToList();
