Transform URL List into HTML Unordered List

by 23. January 2012 16:16
This method will take a flat list of fully qualified URL's and transform them into nested bullets (i.e. HTML unordered lists).  It is a simple method to convert the flat list of URL's into a psuedo tree view.  Here is the C# code to transform the list.
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Reflection;
using System.Xml;
using System.Xml.Xsl;

namespace UrlListToSiteMap
  public class Program
    public static void Main(string[] args)
         This method accepts a text file of fully qualified URLs 
         and will convert into HTML unordered list. 
      string path = Path.GetDirectoryName(Assembly.GetEntryAssembly().Location);
      List urlRecords = File.ReadAllLines(path + @"\UrlList.txt").ToList();
      XmlDocument doc = new XmlDocument();
      doc.AppendChild(doc.CreateNode(XmlNodeType.Element, "SiteMap", ""));
      XmlNode rootNod = doc.ChildNodes[0];
      foreach (string url in urlRecords)
        XmlNode pathNod = rootNod;
        int iNod = 0;
        int iNods = url.ToLower()
          .Replace(@"http://", "").Replace("'", "").Split('/').Count();
        foreach (string nod in url.ToLower()
          .Replace(@"http://", "").Replace("'", "").Split('/'))
          XmlNode subNod = pathNod.SelectSingleNode("Node[@URL='" + nod + "']");
          if (subNod == null)
            string nodType = iNod.Equals(iNods) ? "Leaf" : "Node";
            subNod = doc.CreateNode(XmlNodeType.Element, nodType, "");
            XmlAttribute atr = doc.CreateAttribute("URL");
            atr.Value = nod;
          pathNod = subNod;
      doc.Save(path + @"\SiteMap.xml");
      XslTransform xslt;
      xslt = new XslTransform();
      xslt.Load(path + "SiteMap.xslt");
      xslt.Transform(path + "SiteMapNew.xml", path + "SiteMap.html");

Attached is the XSLT file for the transformation. NOTE: If you only want the folders and not the actual documents, remove the "Leaf" section from the XSLT.

SiteMap.xslt (583.00 bytes)
