我有下面的XML。
<subscription>
<subscription_add_ons type="array">
<subscription_add_on>
<add_on_code>premium_support</add_on_code>
<name>Premium Support</name>
<quantity type="integer">1</quantity>
<unit_amount_in_cents type="integer">15000</unit_amount_in_cents>
<add_on_type>fixed</add_on_type>
<usage_percentage nil="true"></usage_percentage>
<measured_unit_id nil="true"></measured_unit_id>
</subscription_add_on>
</subscription_add_ons>
我的XMLParse函数
public XNode GetXmlNodes(XElement xml, string elementName)
{
List<string> addOnCodes= new List<string>();
//elementName = "subscription_add_ons ";
var addOns = xml.DescendantNodes().Where(x => x.Parent.Name == elementName).FirstOrDefault();
foreach (XNode addOn in addOns)
{
//Needed to do something like this
/*var len = "add_on_code".Length + 2;
var sIndex = addOn.ToString().IndexOf("<add_on_code>") + len;
var eIndex = addOn.ToString().IndexOf("</add_on_code>");
var addOnCode = addOn.ToString().Substring(sIndex, (eIndex - sIndex)).Trim().ToLower();
addOnCodes.Add(addOnCode);*/
}
正如@JonSkeet的评论中所述,我更新了我的片段,如下所示。
var addOns = xml.Descendants(elementName).Single().Elements();
foreach (XNode addOn in addOns)
{
/*addon = {<subscription_add_on>
<add_on_code>premium_support</add_on_code>
<name>Premium Support</name>
<quantity type="integer">1</quantity>
<unit_amount_in_cents type="integer">15000</unit_amount_in_cents>
<add_on_type>fixed</add_on_type>
<usage_percentage nil="true"></usage_percentage>
<measured_unit_id nil="true"></measured_unit_id>
</subscription_add_on>} */
//how to get the addOnCode node value ?
var addOnCode = string.Empty;
addOnCodes.Add(addOnCode);
}
但是我需要的是来自传递的XML,获取所有类型为subscription_add_on
的节点,然后获取add_on_code
中包含的值并将其添加到字符串集合中。
或者一般通过传递类型获取节点的值?尝试使用来自VS Intellisense的可用方法,但没有获得可以做到这一点的确切方法?
谢谢!
以下是使用 Xml Linq (XDOCUMENT( 的解决方案:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;
using System.Xml.Linq;
namespace ConsoleApplication107
{
class Program
{
const string FILENAME = @"c:temptest.xml";
static void Main(string[] args)
{
XDocument doc = XDocument.Load(FILENAME);
var results = doc.Descendants("subscription_add_on").Select(x => new
{
add_on_code = (string)x.Element("add_on_code"),
name = (string)x.Element("name"),
quantity = (int)x.Element("quantity"),
amount = (int)x.Element("unit_amount_in_cents"),
add_on_type = (string)x.Element("add_on_type")
}).ToList();
}
}
}
