After working with a couple of XML projects for the last six months, I am ready to share a class I wrote called XmlHelper which got me through all the complexity of XML and made my life a lot simpler. If you are a XML beginner or have no idea about XML, this article should teach you the very basic concepts that you need to create any type of XML document. If you already have experience in XML, you will probably benefit by using the methods available in XmlHelper. The article evolves from simple concepts about XML to creation of XML documents, to DataSource assignment from XML documents to ListBoxes and DataGrids, and finally to DataSource update from changes made on a DataGrid to update the source XML document.
