如何在xml中逐個選擇逗號分隔的屬性值作為c＃中的循環

Question

我想在循環中逐個使用在TestCondition中定義的逗號分隔屬性值，以便進一步執行我的代碼。請按如下方式找到示例xml：

    <DrWatson>
  <Bugs Name="Testing New things" TestCondition="STATE,STATUS">
    <Bug>
      <family>ESG</family>
      <product>Dr.Watson</product>
      <version>Xpress API</version>
      <productarea>1</productarea>
      <subarea>Blank</subarea>
      <title>Bug.AddNote#1 : Dr.Watson Framework by Aman</title>
      <description>test</description>
      <appLanguages>English~~Bug</appLanguages>
      <platforms>Win XP All~~English~~Bug</platforms>
      <state>Open</state>
      <status>NeedsReview</status>
      <reason>Blank</reason>
      <failureType>Unspecified</failureType>
      <Frequency>Unknown</Frequency>
      <severity>0</severity>
      <priority>0</priority>
      <methodFound>Blank</methodFound>
      <foundInBuild>1</foundInBuild>

我在我的代碼中調用單個屬性值，如下所示：

attrVal_New = Update_Bugs[m].Attributes["TestCondition"].Value;
string attributelowercase = attrVal_New.ToLower();

m++;

我想要的是逐個使用TestCondition下的'STATE'和'STATUS'。請建議。

Answer 1

假設您的真實xml有效

string[] vals = XDocument.Load(fName)
                    .Root
                    .Element("Bugs")
                    .Attribute("TestCondition")
                    .Value.Split(',');

Answer 2

您可以使用foreach循環和string.Split方法，如下所示：

XElement bugsElement = XDocument.Load(fName)
                .Root
                .Element("DrWatson");
List<string> vals = new List<string>();
foreach (XElement el in bugsElement)
{
    vals.AddRange(bugsElement.Attribute("TestCondition").Value.Split(','));
}

string.Split（） - 方法將您的字符串拆分為作為參數傳遞的char的數組，所以

"STATE,STATUS,HELP,WHATEVER".Split(',') 

回報

new string[] {"STATE","STATUS","HELP","WHATEVER"};
