Question

I have an XML tree, which I'd like to parse using Elementtree. My XML looks something like ``` Success 857 E857_INTL_APIXO_16643800_R1 1 2 false 221362908003-1324471823012 NoPaymentFailure 2014-02-03T12:08:51.000Z PaisaPayEscrow Complete false ... ... ``` I want to parse the 6th child of the XML () I am able to get the value of subelements by in…

Accepted Answer

Since the XML document has a namespace declaration (`xmlns="urn:ebay:apis:eBLBaseComponents"`), you have to use universal names when referring to elements in the document. For example, you need `{urn:ebay:apis:eBLBaseComponents}OrderID` instead of just `OrderID`.

This snippet prints all OrderIDs in the document:

```
from xml.etree import ElementTree as ET

NS = "urn:ebay:apis:eBLBaseComponents"

tree = ET.parse('response.xml')

for elem in tree.iter("*"):    # Use tree.getiterator("*") in Python 2.5 and 2.6
    if elem.tag == '{%s}OrderID' % NS:
        print elem.text
```
