一次从一个目录中读取多个.xml。 [英] Reading multiple .xml from a directory one at a time.
本文介绍了一次从一个目录中读取多个.xml。的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我有以下示例代码。它从目录（固定位置）输入.xml文件，并以新格式转换现有.xml文件并将其放在d：\目录中。
现在我在源目录中有多个.xml文件。我需要一次读取每个.xml文件，将其转换为我想要的输出并将其存储到目标目录。
有些人可以帮助我做同样的事情吗？
请注意我是C＃的新手。
我的代码如下。
我的尝试：
I have the following sample code.It takes .xml files input from a directory(fixed location) and convert the existing .xml file in new form and place it in d:\ directory.
Now I have multiple .xml files in the source directory. I need to read each .xml file one at a time convert the same in my desired output and store it to a destination directory.
Can some bu help me out to do the same?
Please note that I am new to C#.
My code is as follows.
What I have tried:
using.System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Xml;
using System.Xml.Schema;
using System.IO;
namespace ConsoleApplication3
{
class Program
{
static void Main(string[] args)
{
XmlDocument doc = new XmlDocument();
doc.Load("D:\\xml_file\\abcd_present.xml");
//I think I need to write here somthing to read the files one by one through some for loop.But it is not exactly getting done.Here I require some help.
XmlTextWriter writer = new XmlTextWriter("d:\\product.xml",system.Text.Encoding.UTF8);
writer.WriteStartDocument(true);
writer.Formatting = Formatting.Indented;
writer.Indentation = 2;
writer.Flush();
writer.WriteStartElement("root");
// loop through each file
//cycle through each child node
String regionName = "", stationName = "", devicetype = "", device = "", startDate = "", endDate = "";
int childNodes = doc.DocumentElement.ChildNodes.Count;
foreach (XmlNode node in doc.DocumentElement.ChildNodes)
{
// first node is the url ... have to go to next loc node
{
//do existing .xml file conversion (I have the code for the same)
}
}
}
}
}
推荐答案
以下是如何处理目录中的多个文件：
Here is how to work with multiple files in a directory:
namespace ProcessDirectory
{
internal static class Program
{
private static void Main(string[] args)
{
//var path = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments);
var path = @"d:\xmlfiles";
foreach (var file in System.IO.Directory.GetFiles(path))
{
ProcessFile(file);
}
Console.ReadKey();
}
static void ProcessFile(string Filename)
{
// do processing here...
Console.WriteLine(Filename);
}
}
}
感谢大家的支持。我是初学者并且学习了不同的方法来做同样的事情。我做了以下编码。
Thanks all for your support. I am a beginner and learnt different way to do the same.I have done the following coding.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Xml;
using System.Xml.Linq;
using System.Xml.Schema;
using System.IO;
namespace ConsoleApplication3
{
class Program
{
static void Main(string[] args)
{
int j = 0;
XmlDocument doc = new XmlDocument();
var path = @"D:\XMLFiles";
foreach (var file in System.IO.Directory.GetFiles(path))
//doc.Load("C:\\Users\\hab77\\Desktop\\ERP xml file\\XMLFiles\\tarun20170526191139_present.xml");
//High Alarm NTAMC.SCADA16.REGION.WR2.BOISAR400.BUS.220KV_BUS_1.HZ=50.0142 Status=GOOD
// string path = "C:\\Users\\hab77\\Desktop\\ERP xml file\\XMLFiles";
//foreach (string fileName in Directory.GetFiles("C:\\Users\\hab77\\Desktop\\ERP xml file\\XMLFiles", "*.xml"))
{
doc.Load(file);
XmlTextWriter writer = new XmlTextWriter("d:\\ERP_XML_" + DateTime.Now.ToString("yyyyMMdd_hhmmss") + "_" + j + ".xml", System.Text.Encoding.UTF8);
writer.WriteStartDocument(true);
writer.Formatting = Formatting.Indented;
writer.Indentation = 2;
writer.Flush();
writer.WriteStartElement("root");
// loop through each file
//cycle through each child node
String regionName = "", substationName = "", devicetype = "", device = "", startDate = "", endDate = "";
int childNodes = doc.DocumentElement.ChildNodes.Count;
foreach (XmlNode node in doc.DocumentElement.ChildNodes)

// first node is the url ... have to go to nexted loc node
// foreach (XmlNode locNode1 in node)

writer.WriteStartElement("Event");
foreach (XmlNode locNode in node)

if (locNode.Name == "TriggerData")
{
// get the content of the loc node
string loc = locNode.InnerText;
Console.WriteLine(loc + Environment.NewLine);
int num = loc.IndexOf(".HZ", 0);
String s1 = loc.Substring(0, num);
num = num + 1;
String s2 = loc.Substring(num, loc.Length - num);//HZ and status
string[] status = s2.Split(' ');
string[] words = s1.Split('.');
//string[] info13 = loc.Split('.').Select(str => str.Trim()).ToArray();
int i = 0;
//String regionName = "", substationName = "", devicetype = "", device = "";
int len = words.Length;
foreach (String s in words)
{
//XmlDocument xm = new XmlDocument();
if (i % 7 == 3)
{

if (i % 7 == 6)
{
device = s;
}
//createNode(regionName, substationName, deviceName,writer);
//Console.WriteLine(xm.InnerXml);
//Console.ReadKey();
Console.WriteLine(s + Environment.NewLine);
i++;
Console.WriteLine(i);
}
foreach (String s in status)
{
int num1 = s.IndexOf("=", 0);
num1++;
String s3 = s.Substring(num1, s.Length - num1);
if (s.Contains("HZ"))
{
writer.WriteStartElement("HZ");
writer.WriteString(s3);
writer.WriteEndElement();
}

writer.WriteEndElement();

}
//if condition

writer.WriteString(regionName);
writer.WriteEndElement();

writer.WriteString(devicetype);
writer.WriteEndElement();
writer.WriteStartElement("device");
writer.WriteString(device);
writer.WriteEndElement();
writer.WriteEndElement();
// write it to the console so you can see its working
//Console.WriteLine(loc + Environment.NewLine);
}
if (locNode.Name == "StartDate")
{
startDate = locNode.InnerText;
writer.WriteStartElement("StartDate");
writer.WriteString(startDate);
writer.WriteEndElement();
}
if (locNode.Name == "EndDate")
{

writer.WriteStartElement("EndDate");
writer.WriteString(endDate);
writer.WriteEndElement();
}
// get the content of the loc node
}
}
// there are a couple child nodes here so only take data from node named loc
}
writer.WriteEndDocument();
writer.Close();

j++;

}
//function to add sftp copy.
}
}
嗨试试这个
hi try this
XmlDocument xdoc = new XmlDocument();
xdoc.Load(Server.MapPath("xml/sample.xml"));
XmlNodeList NodeList = xdoc.SelectNodes("root/*");
foreach (XmlNode Node in NodeList)
{
if (Node.Attributes[0].InnerText.ToLower().Equals("p4"))
{
}
