I have a text file contains 500+ xmlelements like the following:
<Data a="a" b="b" c="c" d="d"><Date runDt="01-01-1900" /></Data>
Can someone please show me how to read/load it so I can retrieve certain attributes/elements? And once I manipulate the data, write it back to a new text file (and needs to be a .txt file without any xml headers).
Thanks :)
Easiest way is to use:
using System.Xml;
XmlDocument xml = new XmlDocument ();
xml.InnerXml = @"<Data a=\"a\" b=\"b\" c=\"c\" d=\"d\"><Date runDt=\"01-01-1900\" /></Data>";
Console.WriteLine (xml.ChildNodes [0].Attributes [0].InnerText);
Will print
a
Using XmlDocument is very easy, just check its fields, variables and methods.
Try this
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;
using System.Xml.Linq;
using System.IO;
namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
string input =
"<Data a=\"a\" b=\"b\" c=\"c\" d=\"d\"><Date runDt=\"01-01-1900\" /></Data>\n" +
"<Data a=\"a\" b=\"b\" c=\"c\" d=\"d\"><Date runDt=\"01-01-1900\" /></Data>\n" +
"<Data a=\"a\" b=\"b\" c=\"c\" d=\"d\"><Date runDt=\"01-01-1900\" /></Data>\n" +
"<Data a=\"a\" b=\"b\" c=\"c\" d=\"d\"><Date runDt=\"01-01-1900\" /></Data>\n" +
"<Data a=\"a\" b=\"b\" c=\"c\" d=\"d\"><Date runDt=\"01-01-1900\" /></Data>\n";
//xml can only contain one root tag. Need to wrap xml in root tag if one is missing
input = string.Format("<Root>{0}</Root>", input);
XDocument doc = XDocument.Parse(input);
// if loading from file
//string input = File.ReadAllText(filename);
//input = string.Format("<Root>{0}</Root>", input);
//XDocument doc = XDocument.Load(filename);
var results = doc.Descendants("Data").Select(x => new
{
a = x.Attribute("a").Value,
b = x.Attribute("b").Value,
c = x.Attribute("c").Value,
d = x.Attribute("d").Value,
date = DateTime.Parse(x.Element("Date").Attribute("runDt").Value)
}).ToList();
}
}
}
