Get XML tag values with Python

[jld730]

If I wanted to get at the value in the tags for 'abstract' and 'purpose' and 'origin' in the below/end xml file, how would I got about doing that? I have tried these two ways, no luck.

# Import system modules
import sys, string, os, xml.dom.minidom
from xml.dom.minidom import parse, parseString

metadata_xml_file = "C:\\Temp\\county_simp2.shp.xml"

parseXMLdoc = parse(metadata_xml_file)

elements = parseXMLdoc.getElementsByTagName("abstract")

xValue = elements[3].attributes['abstract'].value
print xValue

##openFile = open(metadata_xml_file, "r")
##
##line = openFile.readline()
##
##checkList = ["abstract", "purpose", "origin", "pubdate", "current", "caldate", "progress", "update"]
##
##print checkList[0]
####
##while line:
##    if checkList[0] in line:
##        while ("/" + checkList[0]) not in line:
##            start, end = line.find(">"), line.find("<")
##            value = line[start+1:end]
##
##            if value == "":
##                print checklist[0] + " item has no value!"
##
##            if value == "REQUIRED:":
##                print checklist[0] + " item must be chnaged!"
##
##
print "done!"

Thanks in advance for any guidance!

Look at the xml.dom.minidom .Element's getAttribute method...(Node is a subclass of Element, don't worry).
