I think we all know how to use XML documents. For example RSS feeds are basically XML files, as well as sitemaps. Those files may be very important when managing a web site, but those examples are just a small part of the common use of XML documents. Just to make things clear, another example: when you export a Blogger blog, the file you get is an XML file.
When I've written the article on how to create an RSS feed, I discovered a very useful JavaScript snippet that helps us to validate an XML file.
Unfortunately I don't remember where I got it, but, even if I surely rearranged it, if you know the original source, please let me know so that I can give due credit to the author.
Ok, said that, let's see how to do it.

HTML & CSS: header and footer elements for printing
Tweet
In July this year, I've posted an article about collecting data from an xml file in order to display it and eventually print it [JavaScript: get data from an xml file (like a Blogger backup file) and display it (or print it)]. The main reason why I wrote that post is because I wanted to create a unique way of printing The Web Thought. I managed to collect the data (articles body, datestamps, titles and so on) from the xml file generated by Blogger as blog backup, so I now have a good page ready for printing.
Since then, I've worked again on the file and I've changed it a bit, just to include some specific features I needed. Basically I've changed the css style and the JavaScript code. I don't think you might be interested in that part (if you are please let me know so that I can share it), however there's a bit of code I would like to show you. Basically we want to create footers and headers for every printed page.

JavaScript: get data from an xml file (like a Blogger backup file) and display it (or print it) - Part 2
Tweet
As promised, in the following article I will explain the code published in my previous post. I don't know how many of you are interested in explanations, but because I think that understanding things is better than merely copying examples, I will torture you with this. You've been warned!

JavaScript: get data from an xml file (like a Blogger backup file) and display it (or print it) - Part 1
Tweet
I've been running around this post quite a lot. I know that it could contain valuable information for everyone and specifically for Bloggers, but there's so much into it that I don't know where to start.
Anyway... The point here is:
1) take the Blogger backup file (xml) - or any other properly formed xml file (an Atom feed as well);
2) clean it up - if needed;
3) build an HTML page that gets the data from the xml file (using JavaScript);
4) properly style the page.
As you can see the task is not that easy... or is it? Read on, and judge for yourself.

XML: build a sitemap for search engines
Tweet
A Sitemap is an XML file which contains all the information needed by search engines to crawl a web site, and eventually index it more efficiently. The XML file mainly contains URLs and additional information which can be used by search engines crawlers. If a Sitemap is not present in the root of a web site, the crawlers usually will follow the links inside a page and try to "discover" all the pages of the site. With a Sitemap, that process is done more efficiently, quickly and the web master is sure that all relevant pages are indeed analysed by search engines spiders. Sitemaps do not guarantee that a web site is indexed and ranked, however they help a lot the process.
There are many Sitemaps creator on the web, however I would like to explain how to build one yourself. As a side note, you should know that RSS feeds can be used as Sitemaps in tools like Google Webmaster, however it is better to use the Sitemap protocol to ensure that other web spiders understand the structure of your site.
