part1

Form and email / date appending email-database.xml

online form

cgi receives email address and appends it to email-database.xml file

TO DO: date format not necessarily the best format - check others

http://pzwart3.wdka.hro.nl/~acastro/cgi-bin/traces_form_handler.cgi:

#!/usr/bin/python2.6
import cgi, cgitb, lxml.etree, datetime, os

today = datetime.datetime.now().strftime("%Y-%m-%d") #not sure is this is the best format

# Create instance of FieldStorage 
form = cgi.FieldStorage() 
# Get email from form 
email = form.getvalue('email') 


print "Content-Type: text/html"  
print                         
print "<TITLE>Form</TITLE>"
print "<H4>Your form was successfully added.<br />Shortly you will receive a message at %s </H4>" % (email)


#APPEND EMAIL AND DATE TO XML FILE
if os.path.exists('/home/acastro/public_html/cgi-bin/traces-database.xml'):
	print  
else:  
	root = lxml.etree.Element('email-address')
	son = lxml.etree.SubElement(root, 'entries')
	tree = lxml.etree.ElementTree(root)
	tree.write('/home/acastro/public_html/cgi-bin/traces-database.xml', pretty_print=True, xml_declaration=True,encoding='utf-8')
	tree.close()


	#f = 'email-database.xml'
doc = lxml.etree.parse('/home/acastro/public_html/cgi-bin/traces-database.xml')
entries = doc.find('entries') # find root element




node_today = '//date[@date="'+ str(today) + '"]'
 
#check if todays date element is present
if today not in doc.xpath('//@date'): 
	date = lxml.etree.SubElement(entries, "date", attrib={'date':today} )  	#append date SubElement date
	addrs = lxml.etree.SubElement(date, "address")#append grandchild
	addrs.text = str(email)
	doc.write('/home/acastro/public_html/cgi-bin/traces-database.xml', xml_declaration=True,  encoding='utf-8') #write

else:
	test = doc.xpath(node_today)
	print lxml.etree.tostring(test[0])
	addrs = lxml.etree.SubElement(test[0], "address")#append grandchild
	addrs.text = email
	doc.write('/home/acastro/public_html/cgi-bin/traces-database.xml', xml_declaration=True,  encoding='utf-8') #write

part2

Days and Emails calculations

Other py script which:

parse the email-database.xml (every day)

Script which parses xml database. Checks the dates and email address under each dat3.

According the date decide what part of story will be told

#! /usr/bin/python
# coding: utf-8
import lxml.etree, urllib2
#Script which parses xml database. Checks the dates and email address under each date
 
f = ('traces-email-database.xml') # change to local
#f = urllib2.urlopen('http://pzwart3.wdka.hro.nl/~acastro/cgi-bin/traces-email-database.xml') #ERROR! ??permissions
 
 
doc = lxml.etree.parse(f)
 
# find dates
dates = doc.xpath('//date')



#create the dictionary {date: [address, address]}
dateDict = {}
for date in dates:
    #print lxml.etree.tostring(date)
    date_is_attr = date.get("date")
    myAddrs = doc.xpath("//date[@date='{0}']/address/text()".format(date_is_attr))
    dateDict[date_is_attr] = myAddrs


# compare the dates with the current
from datetime import *
import re
today = str(date.today())
yesterday = str(date.today()-timedelta(days=1))
beforeyesterday = str(date.today()-timedelta(days=2))



for date, addrs in dateDict.iteritems():
    #print date
    #print addrs
    print
    if str(date) == today :
        print "send first mail to:"
        for a in addrs :
            print a
    elif date == yesterday :
        print "send second mail to:"
        for a in addrs :
            print a
    elif date == beforeyesterday : 
        print "send third mail to:"
        for a in addrs :
            print a
