The result of an xpath evaluation is a list of node, which you can
perform
another xpatheval() on :
import libxml2
doc = libxml2.parseFile(XmlFile)
root = doc.getRootElement()
line_nodes = root.xpathEval('lines/line')
for line_node in line_nodes:
print line_node.xpathEval('lineno')[0].content
print line_node.xpathEval('productcode')[0].content
doc.freeDoc()
