for node in parentnode:
    alist=node.getElementsByTagName('text')
    for a in alist:
        t=a.childNodes[0].nodeValue
        print authortext

desire output that i want

Unless your actual XML is much more complicated, you can navigate the DOM tree and get the child nodes you want from the text children in the parts nodes that are children of computer:

import xml.dom.minidom

file=('sample.xml')
xmldoc=xml.dom.minidom.parse(file)
computerNode = xmldoc.getElementsByTagName('computer')
for computerChild in computerNode:
    for parts in computerChild.childNodes:
       for partsChild in parts.childNodes:
          if partsChild.nodeType == xml.dom.Node.ELEMENT_NODE: 
             if partsChild.tagName == 'text':
                print partsChild.childNodes[0].nodeValue

To use XPath, as I had suggested before, and simpler DOM navigation, its best to use the Element Tree API.
