如何将xml中以逗号分隔的属性值逐个提取为c#中的循环

Question

我想使用在xml中的TestCondition下定义的逗号分隔属性值，逐个in循环，以便进一步执行我的code.Please查找示例xml，如下所示：

    <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>

      <duplicateId>Blank</duplicateId>

    </Bug>
  </Bugs>
</DrWatson>

我在代码中调用单个属性值，如下所示：

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

m++;

我想要的是使用one.Please suggest在TestCondition one下提供的‘状态’和‘状态’。

Answer 1

假设您的真实xml是有效的

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

Answer 2

您可以使用foreach循环和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()-method在作为参数传递的字符处将字符串拆分为一个数组，因此

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

返回

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