I'm confused, what does the last post have to do with the one before it? If you have separate questions can you start a fresh post for each?
For the last post you need xmlDoc.getElementsByTagName("instructions").childNodes.childNodes.nodeValue, for the previous one you need paramet/para1/@text and the string value of paramet/para1. Otherwise try to provide a clearer description of what you currently have and what exactly you need.
