How to Import XLM Into Visual Basic
Read XML files in VB. (Jupiterimages/ Images)

XML files are widely used and it can be handy to know how to import XML data into your Visual Basic application. To accomplish this task you need to use the "System.Xml" assembly. This assembly contains the "XmlTextReader" class, which you can use to read Externsible Markup Language (XML) from a file. The reader provides direct parsing and tokenizing of XML. The data read is stored in memory that you can access and use in your VB program.
