将 xml 读入 LINQ 格式以检查日志文件数据 - 列表格式的条件 - linq 未拾取重新格式化的 xml

问题描述 投票：0回答：1

我有一个项目，它读取每个构建区域的预期构建结果的 xml，并与构建日志进行比较以查看构建是否通过。现在，linq 在单独的结果行中显示每个条件，但是（因为我循环遍历每个 linq 结果行以检查是否成功）我需要能够在同一时间，而不是不同时间。否则我可能会检查日志文件的错误行。请注意，有时有两个成功标准，但并非总是如此。这只是我需要立即检查的两个条件。 为了进行此更改，我将 SuccessCriteria 标签移出“条件”标签并移至“条件”下方。进行此更改后，linq 不会获取 xml 行。我的完整 xml 中应该有大约 69 行 results_b ，但它选取了一些我没有显示为旧格式的部分。我尝试在 LINQ 中将 cName = (string)p.Attribute("name") 更改为 cName = (string)b.Attribute("name")，但结果相同。 cValue 同时也发生了类似的变化。

我的问题是，如何更改 LINQ 以获取完整的 xml 文件，以及如何更改 groupBy_b 以同时检查这两个条件？我希望将条件放在一个列表中，但周围还有其他数据，例如构建机器、进程名称和成功标准。 例如，对于某些日志，ParseISLogStats，我放入 xml 中的表看起来像这样（因此我需要检查日志中的 BuildProject 和 BaseBuildArea 是否正确，因为它们是不同的列，但成功标准对于这两个来说只有一个条件）：

ParseISLogStats    Desctiption=nightly v17 partb   Projects=8   Status=Success
ParseISLogStats    Description=nightly v17 partb   Projects=8   Status=Success
ParseISLogStats    Description=nightly v17         Projects=33  Status=Success

我一直在看这些例子： linq linq

到目前为止，我有这段代码（添加了 groupBy 来尝试将条件一起放入列表中）：

void ReadXml()
{
    int i_results = 0; //0 is successful for all; if it increases we have failed in one
    XmlDocument xml = new XmlDocument();
    string path = Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location);
    string newPath = Path.GetFullPath(Path.Combine(path, @"..\.."));
    string finalPathXmlb = Path.GetFullPath(Path.Combine(newPath, @"BuildVerificationBuildAttributes_b.xml")); //new format

    teamPost = "";

    //linq 
    XDocument xmlDoc2 = XDocument.Load(finalPathXmlb);
    //XElement buildVerificationElement = xmlDoc1.Element("BuildVerification");
    //IEnumerable<XElement> buildElements = buildVerificationElement.Elements("build");
    //IEnumerable<XElement> buildMachines = buildElements.Elements("BuildMachine");

    //get just the times from the xml
    //var codeFreezeTime = xmlDoc1.Descendants("codeFreezeTime").First()?.Value;
    //logToFileAndScreen(codeFreezeTime);

    //get build info from xml, such as process (log name), condition, successCriteria, build machine, start time header, 
    IEnumerable<XElement> processes = buildMachines.Elements("Process");

    var results_b =
        xmlDoc2.Descendants("build")
        .SelectMany(b => b.Descendants("Process")
        .SelectMany(p => p.Descendants("Condition")
        .SelectMany(c => c.Descendants("SuccessCriteria")
        .Select(sc => new
        {
            buildMach = (string)b.Element("BuildMachine"),
            p1 = (string)p.Element("ProcessName"),
            startTimeHeader = (string)p.Element("startTimeHeader"),
            cName = (string)c.Attribute("name"),
            cValue = (string)c.Attribute("value"),
            f1 = (string)sc.Element("field"),
            c1 = (string)sc.Element("comparison"),
            v1 = (string)sc.Element("value")
        })))).ToList();
    
    var groups_b = results_b.GroupBy(x => new { build_machine = x.buildMach, process_name = x.p1, name = x.cName }).ToList();
} //ParseLogFile

我希望我的 groups_b 看起来像这样（但由于 linq 不工作，它永远不会这样做，但我认为如果 linq 工作的话，我的 groups_b 中的它也不正确）：

{buildMach = mach64, p1=ParseISLogStats, startTimeHeader = StartTime, {cName=Description, cValue=nightly v17 partb, cName=Projects, cValue=8}, f1=Status, c1=equal, v1=Succcess}
{buildmach = mach64, p1=ParseISLogStats, startTimeheader = StartTime, {cName=Description, cValue = nightly v17, cName=Projects, cValue=33},f1=status, c1=equal, v1=Success}

这就是我的 xml 的样子：

当您以这种方式链接 

.SelectMany()
LINQ 函数时，最终的 
.Select()
只能访问最新/最里面的 
SuccessCriteria
元素。

您需要嵌套它们，而不是链接函数。比如：

var results_b = xmlDoc2.Descendants("build")
    .SelectMany(b => b.Descendants("Process")
        .SelectMany(p => p.Descendants("Condition")
            .SelectMany(c => c.Descendants("SuccessCriteria")
                .Select(sc => new {
                    buildMach = (string)b.Element("BuildMachine"),
                    p1 = (string)p.Element("ProcessName"),
                    startTimeHeader = (string)p.Element("startTimeHeader"),
                    cName = (string)c.Attribute("name"),
                    cValue = (string)c.Attribute("value"),
                    f1 = (string)sc.Element("field"),
                    c1 = (string)sc.Element("comparison"),
                    v1 = (string)sc.Element("value")
                })
            )
        )
    )
    .ToList();

如果您不喜欢上面的深度嵌套，您可以考虑使用 LINQ 查询语法，它允许您构建嵌套元素的集合，并且仍然可以在最终的 select 子句中访问所有这些元素。

var results_b = (
    from b in xmlDoc2.Descendants("build")
    from p in b.Descendants("Process")
    from c in p.Descendants("Condition")
    from sc in c.Descendants("SuccessCriteria")
    select new {
        buildMach = (string)b.Element("BuildMachine"),
        p1 = (string)p.Element("ProcessName"),
        startTimeHeader = (string)p.Element("startTimeHeader"),
        cName = (string)c.Attribute("name"),
        cValue = (string)c.Attribute("value"),
        f1 = (string)sc.Element("field"),
        c1 = (string)sc.Element("comparison"),
        v1 = (string)sc.Element("value")
    })
    .ToList();
