A question about DOM parser used with Python
- by fixxxer
I'm using the following python code to search for a node in an XML file and changing the value of an attribute of one of it's children.Changes are happening correctly when the node is displayed using toxml().But, when it is written to a file, the attributes rearrange themselves(as seen in the Source and the Final XML below). Could anyone explain how and why this happen?
Python code:
#!/usr/bin/env python
import xml
from xml.dom.minidom import parse
dom=parse("max.xml")
#print "Please enter the store name:"
for sku in dom.getElementsByTagName("node"):
if sku.getAttribute("name") == "store":
sku.childNodes[1].childNodes[5].setAttribute("value","Delhi,India")
print sku.toxml()
xml.dom.ext.PrettyPrint(dom, open("new.xml", "w"))
a part of the Source XML:
<node name='store' node_id='515' module='mpx.lib.node.simple_value.SimpleValue' config_builder='' inherant='false' description='Configurable Value'>
<match>
<property name='1' value='point'/>
<property name='2' value='0'/>
<property name='val' value='Store# 09204 Staten Island, NY'/>
<property name='3' value='str'/>
</match>
</node>
Final XML :
<node config_builder="" description="Configurable Value" inherant="false" module="mpx.lib.node.simple_value.SimpleValue" name="store" node_id="515">
<match>
<property name="1" value="point"/>
<property name="2" value="0"/>
<property name="val" value="Delhi,India"/>
<property name="3" value="str"/>
</match>
</node>
