Google SiteMap

[shapper]

Hello,

I am trying to convert an Asp.Net 2.0 XML sitemap file to a Google's
sitemap file.

I am posting the formats of both files.

1. How can I do the conversion?

2. And can I use an .ashx Asp.Net file that when the .ashx file is
called the Google XML file is generated?

Thank You,
Miguel

GOOGLE SiteMap

<?xml version="1.0" encoding="UTF-8"?>
< urlset xmlns="http://www.google.com/schemas/sitemap/0.84">
< url>
< loc>http://www.mydomain.com/example.aspx</loc>
< lastmod>2005-01-01</lastmod>
< changefreq>daily</changefreq>
< priority>0.8</priority>
</url>
</urlset>

ASP.NET 2.0 Site Map

<?xml version="1.0" encoding="utf-8" ?>
<siteMap
xmlns = "http://schemas.microsoft.com/AspNet/SiteMap-File-1.0" >
<siteMapNode>
<siteMapNode
url = "~/example.aspx"
changefreq = "daily"
lastmod = "2005-01-01"
description = "My example page and its contents"
priority = "0.8"
title = "Example page" />
</siteMapNode>
</siteMap>

Note: description and title should be droped when converting from
Asp.Net to Google sitemap.

Have you seen this?

"This project builds Google (tm) compatible sitemap files from ASP.NET
SiteMaps. A simple control that exposes ASP.NET SiteMaps as HTML to help
other search engines index the site is also provided."

Here's a handler that should get you going.

re:

I am trying to convert an Asp.Net 2.0 XML sitemap file to a Google's sitemap file.

Try the ASP.NET to Google sitemap converter:

The download link is :

Hi,

I saw the links. However, I am trying to do the following:
Each web project will have only one web site map file for each culture.
Inside each node of the web site map I add a attribute such as:

Google=True
or
Footer=True

This way I will be able to use those values to generate Google XML web
sites maps on the fly with an ashx file or even get nodes from the web
site map in my runtime code to fill the footer.

This way I don't have to mantain many web sitemaps.

This is way I am trying to figure out how to make the XML conversion
with XLST and using conditions to.

Thanks,
Miguel
