# Node name = '.tag'
# Node attribute = '.attrib'
# Node value = '.text'

#

Element.findall() finds only elements with a tag which are direct children of the current element. Element.find() finds the first child with a particular tag, and Element.text accesses the element’s text content. Element.get() accesses the element’s attributes:

# XML Handling

[To write an XML file using Etree: tree.write("/tmp/" + executionID +".xml") ]

import xml.etree.ElementTree as ET

# Get element object:

# First get root element
# From File:

tree = ET.parse('country_data.xml')
root = tree.getroot()

# From xml string
xml_str = '''
<project>
    <publishers>
...
...
    </publishers>
<project>




root = ET.fromstring(xml_str)
updated_xml_str = ET.tostring(root)
====
# Get desired element object to set using XPath: text or attribute


DESCRIPTION_PATH = './publishers/hudson.plugins.descriptionsetter.DescriptionSetterPublisher/description'

DESCRIPTION_PATH is path relative to the root element (in case of jenkins, the root element is project)

root.find(DESCRIPTION_PATH).text = 'Updated Text'


# Create new element:
# create new child object:
new_element_object = 'ET.Element("new_element")

# Add the new_element_object to the existing element you want;
for root:
root.append(new_element_object)

OR (a one-liner):
root.find(DESCRIPTION_PATH).append('new_element_object')

OR (use Subelement);
ET.SubElement(root.find(DESCRIPTION_PATH), tag='new_element')
ET.SubElement(root.find(DESCRIPTION_PATH), 'new_element')   # Without tag variable

OR (with text setting)
ET.SubElement(root.find(DESCRIPTION_PATH), 'new_element').text = 'HELLO MAN JEE!'

# element.findall(path) : gives a list of all elements at the given path relative to the element it is operated on
it gives list of all the element: to find the text, you need to use the method 'find'

y = root.findall('builders/hudson.tasks.Shell')
    for x in y:
        print x.find('command').text

get all POST args in python flask

http://stackoverflow.com/questions/25410944/print-all-post-request-parameters-without-knowing-their-names

request.args returns a MultiDict. It can have multiple values for each key. In order to print all parameters, you can try:
The code below works for URLs with parameters added,like:

 http://www.webservice.my/rest?extraKey=extraValue
    multi_dict = request.args
    for key in multi_dict:
        print multi_dict.get(key)
        print multi_dict.getlist(key)

For parameters embedded within the POST request as a form:

dict = request.form
for key in dict:
    print 'form key '+dict[key]

See the example here and you will have a good idea.
