我尝试使用XDocument类解析xml文件,条件是如果子节点与给定字符串匹配,则选择其父节点.

<SalesQuotes xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://api.some.com/version/1">
  <Pagination>
    <NumberOfItems>2380</NumberOfItems>
    <PageSize>200</PageSize>
    <PageNumber>1</PageNumber>
    <NumberOfPages>12</NumberOfPages>
  </Pagination>
  <SalesQuote>
    <Guid>825634b9-28f5-4aa7-98e7-5e4a4ed6bc6a</Guid>
    <LastModifiedOn>2018-01-09T12:23:56.6133445</LastModifiedOn>
    <Comments>Please note:

    </Comments>
  </SalesQuote>
</SalesQuotes>

我试过用

var contents = File.ReadAllText(path: "test1.xml");
var doc = XDocument.Parse(contents);
var root = doc.Root;
var sq = root.Elements("SalesQuote");//return null

var theQuote = root.Elements("SalesQuote").Where(el => el.Element("Guid").Value == "825634b9-28f5-4aa7-98e7-5e4a4ed6bc6a");//return null

var theAlternativeQuote =
            from el in doc.Descendants("SalesQuote").Elements("Guid")
            where el.Value == "825634b9-28f5-4aa7-98e7-5e4a4ed6bc6a"
            select el;//return null

我似乎无法找到什么是错的.

任何帮助深表感谢!谢谢.
