I'll cut straight to the chase!
Here's my XML, it contains a folder structure and a list of files with their md5 hashes.
<?xml version="1.0" encoding="utf-8"?>
<dir name="Root">
<dir name="Folder01">
<dir name="SubFolder01">
<file md5="77c34f94b0827a2a511b7c9113fd8e31" name="file01.lua" />
<file md5="47e656c824a3de6fd6bdf7429045b570" name="file02.lua" />
<file md5="8c9d3b467fbb3173bebed99bae400995" name="file03.lua" />
<file md5="ade88ad29426e49c9a81e923bb428445" name="file04.lua" />
</dir>
<dir name="SubFolder02">
<dir name="SubFolder03">
<dir name="SubFolder04">
<file md5="e1a8566380b2a4256e1792b48705058c" name="file.png" />
</dir>
</dir>
</dir>
</dir>
<dir name="Folder02">
<dir name="SubFolder01">
<file md5="12f6a2a9e85817fdf6f791f1b0fe37b3" name="File01.lua" />
</dir>
</dir>
</dir>
I would like to read in this XML and generate a list of files with their md5's like this...
Root\Folder01\SubFolder01\file01.lua, 77c34f94b0827a2a511b7c9113fd8e31
Root\Folder01\SubFolder01\file02.lua, 47e656c824a3de6fd6bdf7429045b570
Root\Folder01\SubFolder01\file03.lua, 8c9d3b467fbb3173bebed99bae400995
Root\Folder01\SubFolder01\file04.lua, ade88ad29426e49c9a81e923bb428445
Root\Folder01\SubFolder02\SubFolder03\SubFolder04\file.png, e1a8566380b2a4256e1792b48705058c
Root\Folder02\SubFolder01\File01.lua, 12f6a2a9e85817fdf6f791f1b0fe37b3
This is the (broken) code I have so far
var SingleFiles = SourceXMLFile.Descendants("dir")
.Select(x => new
{
FileName = (string)x.Attribute("name"),
md5 = (string)x.Attribute("md5")
});
I realise I neeed to iterate through the nodes and descendants to build the Filename string based on parents etc. but I'm a little burnt out at the moment (having tried numerous ways!) if anyone could help I'd be extremely grateful.
UPDATE : While the answer given by Ron.BI may not have actually been an answer, it did give me a push in the right direction to figure it out myself.
XmlReader rdr = XmlReader.Create(new System.IO.StringReader(XMLasString));
string newPath = "";
while (rdr.Read())
{
if (rdr.NodeType == XmlNodeType.Element)
{
if (rdr.LocalName == "file")
Console.WriteLine(newPath + rdr.GetAttribute(1) + " " + rdr.GetAttribute(0));
else
newPath = newPath + (rdr.GetAttribute(0)) + Path.DirectorySeparatorChar;
}
}
I'm going to go through the other answers now and mark the 'best' one. Thanks for all your help.
var doc = XDocument.Parse(xml);
string[] filesAndMD5 = doc.Descendants("file")
.Select(node => GetFullPath(node) + ", " + node.Attribute("md5").Value)
.ToArray();
filesAndMD5.ForEach(Console.WriteLine);
public string GetFullPath(XElement node)
{
string res = "";
while(node != null)
{
res = Path.Combine(node.Attribute("name").Value, res);
node = node.Parent;
}
return res;
}
prints:
Root\Folder01\SubFolder01\file01.lua, 77c34f94b0827a2a511b7c9113fd8e31
Root\Folder01\SubFolder01\file02.lua, 47e656c824a3de6fd6bdf7429045b570
Root\Folder01\SubFolder01\file03.lua, 8c9d3b467fbb3173bebed99bae400995
Root\Folder01\SubFolder01\file04.lua, ade88ad29426e49c9a81e923bb428445
Root\Folder01\SubFolder02\SubFolder03\SubFolder04\file.png, e1a8566380b2a4256e1792b48705058c
Root\Folder02\SubFolder01\File01.lua, 12f6a2a9e85817fdf6f791f1b0fe37b3
var xDoc = XDocument.Parse(xmlstring);
var files = xDoc.Descendants("file")
.Select(f => String.Format("{0} {1}",
String.Join("/",GetPath(f).Reverse()),
f.Attribute("md5").Value))
.ToList();
IEnumerable<string> GetPath(XElement e)
{
while(e!=null) {
yield return e.Attribute("name").Value;
e = e.Parent;
}
}
A slighty different approach:
using System;
using System.Collections.Generic;
using System.IO;
using System.Xml.Linq;
namespace Demo
{
class Program
{
void run()
{
XDocument doc = XDocument.Load("C:\\TEST\\TEST.XML");
var filenames = ExtractFilenamesAndHashes(doc);
filenames.Print();
}
public IEnumerable<string> ExtractFilenamesAndHashes(XDocument doc)
{
return extractFilenamesAndHashes(doc.Root, doc.Root.Attribute("name").Value);
}
IEnumerable<string> extractFilenamesAndHashes(XElement root, string path)
{
foreach (var folder in root.Elements("dir"))
foreach (var filename in extractFilenamesAndHashes(folder, Path.Combine(path, folder.Attribute("name").Value)))
yield return filename;
foreach (var file in root.Elements("file"))
yield return Path.Combine(path, file.Attribute("name").Value + ", " + file.Attribute("md5").Value);
}
static void Main()
{
new Program().run();
}
}
static class DemoUtil
{
public static void Print(this object self)
{
Console.WriteLine(self);
}
public static void Print(this string self)
{
Console.WriteLine(self);
}
public static void Print<T>(this IEnumerable<T> self)
{
foreach (var item in self)
Console.WriteLine(item);
}
}
}
