我正在尝试阅读，并使用以下结构处理XML。
<?xml version="1.0" encoding="utf-8"?>

每个打印套件都需要单独打印。由于应用程序将在.NET 2.0上运行，我想避免使用LINQ。
请帮助为此结构编写循环。我需要阅读单独的'print_set'，其中包含每个'line'的属性。
感谢您提出建议我现在通过使用以下代码获得解决方案，这可能有助于完整：对其他人
using (XmlReader reader = XmlReader.Create(xml_url))
{
// Console.WriteLine("Output Using XMLReader:");
int i = 1;
while (reader.Read())
{
switch(reader.NodeType){
//If Element, check which element
case XmlNodeType.Element:
switch(reader.Name){
//If Print_format, get modified time
case "print_format":
Console.WriteLine("Start of Print Fomrat");
Console.WriteLine("Modified Time:" + reader.GetAttribute("sale_modified_time"));
break;
//If print_set start print variable
case "print_set":
Console.WriteLine("Print Set Start:"+i);
break;
//If line, print line details
case "line":
if (reader.GetAttribute("height") == null)
{
Console.WriteLine("Height is null");
}
if (reader.GetAttribute("font") == null)
{
Console.WriteLine("Font is null");
}
if (reader.GetAttribute("weight") == null)
{
Console.WriteLine("Weight is null");
}
if (reader.GetAttribute("align") == null)
{
Console.WriteLine("Align is null");
}
Console.WriteLine(reader.GetAttribute("align") + " " + reader.GetAttribute("weight") + " " + reader.GetAttribute("font") + " " + reader.GetAttribute("height") + " " + reader.ReadString());
break;
}
break;
case XmlNodeType.EndElement:
switch (reader.Name)
{
//If End Element, check if it's Print Set
//If reader.Name is print_set, the send to printer, and end the print page.
//Else do nothing
case "print_set":
Console.WriteLine("End of Print set:"+i);
i++;
Console.WriteLine("--------------------------------------");
break;
case "print_format":
Console.WriteLine("End of print format");
break;
}
break;
}
}
}
如果您尝试从xml字符串中读取数据，则可以使用XMLtext reader 如下所示：
using (XmlTextReader reader = new XmlTextReader(new System.IO.StringReader(server_data)))
{
}
