Hello,
I hope this works:
#!/usr/bin/python
from BeautifulSoup import BeautifulStoneSoup
#If the XML you provided is in a file named 'problem'
xml_struc = open('problem','r')
soup = BeautifulStoneSoup(xml_struc)
list_of_tags = soup.findAll('property')
for tag in list_of_tags:
if tag['value'] == "9998":
tag['value'] = "9999" #or whatever number you like
soup_str = str(soup)
f = open('output', 'w')
f.write(soup_str)
f.close()
xml_struc.close()
