Create XML using python

[shanavas]

Hi All,

I have been searching for a sample/basis python script which would create/generate a xml file out of oracle database. I don't have previous experience with Python. could you please help me on this. Below is the detail description on the task.

For example if i have table called "EMPLOYEE" in my oracle datbase and it is contains are "EMPNO,ENAME,SA L,DEPTNO"(colum n name) my XML file should looks like the below
<EMPLOYEE>
<EMPNO>123</EMPNO>
<ENAME>Shan</ENAME>
<SAL>2000</SAL>
<DEPTNO>100</DEPTNO>
</EMPLOYEE>
<EMPLOYEE>
<EMPNO>345</EMPNO>
<ENAME>Purna</ENAME>
<SAL>2000</SAL>
<DEPTNO>200</DEPTNO>
</EMPLOYEE>

Hi,

Thanks for your quick response and apologies for not coming back to you early. Recruitment had changed a bit and below are the full details.

I have a oracle table with the following data:

Tag_name, tag_value
empname Smith
empno 5102
sal 600
deptno 10
empname Jhon
empno 4102
sal 800
deptno 20

and my xml should look like

<employeedetails>
   <employee>
	<empname>Smith</empname>
	<empno>5102</empno>
	<sal>600</sal>
	<deptno>10</deptno>
   </employee>
   <employee>
	<empname>john</empname>
	<empno>4102</empno>
	<sal>800</sal>
	<deptno>20</deptno>
   </employee>
<employeedetails>

below is the code am using to generate the XML

from xml.etree.ElementTree import Element, SubElement, Comment
from xml.etree import ElementTree
from xml.dom import minidom
import cx_Oracle

def prettify(elem):
    """Return a pretty-printed XML string for the Element.
    """
    rough_string = ElementTree.tostring(elem, 'utf-8')
    reparsed = minidom.parseString(rough_string)
    return reparsed.toprettyxml(indent="  ")

db = cx_Oracle.connect("username/pwd@servername") #Make it as a file read
cursor = db.cursor()
cursor.arraysize = 500
cursor.execute("select * from employee") #Get the table name from input parameter
top = Element('employeedetails')
child = SubElement(top,'employee')
for i in cursor:
    sub_child = SubElement(child, i[1])
    sub_child.text = i[2]
print (prettify(top))

insted of getting the desired output am getting ouput like below

<employeedetails>
   <employee>
	<empname>Smith</empname>
	<empno>5102</empno>
	<sal>600</sal>
	<deptno>10</deptno>
	<empname>john</empname>
	<empno>4102</empno>
	<sal>800</sal>
	<deptno>20</deptno>
   </employee>
</employeedetails>
