我需要有关 LINQ to XML 的一些帮助。我有以下 XML;
<GcctTestData>
<TestDriveRequest Record="1">
<element name="Time Zone">(GMT+05:30)</element>
<element name="Requested Dealer">Concorde</element>
<element name="Model Year">1999</element>
<element name="Make">Tata</element>
<element name="Model/Vehicle Line">Indica</element>
</TestDriveRequest>
<TestDriveRequest Record="2">
<element name="Time Zone">(GMT+05:30)</element>
<element name="Requested Dealer">Kun"</element>
<element name="Model Year">2020"</element>
<element name="Make">BMW"</element>
<element name="Model/Vehicle Line">3-series</element>
</TestDriveRequest>
<TestDriveRequest Record="3">
<element name="Time Zone">(GMT+05:30)</element>
<element name="Requested Dealer">KUN Hyundai</element>
<element name="Model Year">2001</element>
<element name="Make">Hyundai</element>
<element name="Model/Vehicle Line">Verna</element>
</TestDriveRequest>
</GcctTestData>
我尝试了如下:
IEnumerable<XElement> xElements =
from element in root.Elements("TestDriveRequest")
where element.Attribute("Record").Value == "1"
select element;
foreach (XElement el in xElements.Descendants().Where(p => !p.HasElements))
{
int keyInt = 0;
string keyName = el.Attribute("name").Value;
while (keyValuePairs.ContainsKey(keyName))
{
keyName = $"{el.Attribute("name").Value}_{keyInt++}";
}
keyValuePairs.Add(keyName, el.Value);
}
我必须获取记录值为 1 的父元素的 元素 的元素 name 属性值
但是 linq 查询没有获取它...
最佳答案
您需要使用root.Descendants
而不是root.Elements
。
例如,
IEnumerable<XElement> xElements = from element in root.Descendants("TestDriveRequest")
where element.Attribute("Record").Value == "1"
select element;
XContainer.Elements
Returns a filtered collection of the child elements of this element or document, in document order. Only elements that have a matching XName are included in the collection.
XContainer.后代
Returns a filtered collection of the descendant elements for this document or element, in document order. Only elements that have a matching XName are included in the collection Output
完整代码
IEnumerable<XElement> xElements = from element in root.Descendants("TestDriveRequest")
where element.Attribute("Record").Value == "1"
select element;
foreach (XElement el in xElements.Descendants().Where(p => !p.HasElements))
{
int keyInt = 0;
string keyName = el.Attribute("name").Value;
while (keyValuePairs.ContainsKey(keyName))
{
keyName = $"{el.Attribute("name").Value}_{keyInt++}";
}
keyValuePairs.Add(keyName, el.Value);
}
示例输出
关于c# - Linq XML 查询属性中具有特定值的父级的后代,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/59643060/
