How can I preserve whitespaces with python 2.7 lxml? - python

I have a huge xml file (thousands of lines) and I need to change some attribute parameters.
Xml looks like this:
<person id="name" name="pers_name">
<group id="Common">
<emotion id="smile">
<texture texture="smile" x="-131" y="-17" />
<effect name="name1" x="51" y="438" />
<effect name="name2" x="61" y="419" />
<effect name="name3" x="55" y="312" />
</emotion>
</group>
</person>
After I did it and wrote it with tree.write(path, encoding='utf-8', xml_declaration=True) I lost whitespaces before closing tag.
How can I preserve it?
<person id="name" name="pers_name">
<group id="Common">
<emotion id="smile">
<texture texture="smile" x="-131" y="-17"/>
<effect name="name1" x="51" y="438"/>
<effect name="name2" x="61" y="419"/>
<effect name="name3" x="55" y="312"/>
</emotion>
</group>
</person>
Code
from lxml import etree
# Offsets
x_offset = -10
y_offset = -20
tree = etree.parse(path)
XML = tree.getroot()
for effect in XML.iter('effect'):
texture_offset_x = int(effect.get('texture_offset_x')) + x_offset
texture_offset_y = int(effect.get('texture_offset_y')) + y_offset
effect.set('texture_offset_x', str(texture_offset_x))
effect.set('texture_offset_y', str(texture_offset_y))
tree.write(path, encoding='utf-8', xml_declaration=True)

i need all the tag values after Change_module.i tried some online help in Stack overflow but it didn't work.
I never worked with XML documents before and here is the sample code i
tried from Stack Overflow.
import xml.etree.ElementTree as ET
import pandas as pd
import numpy as np
tree = ET.parse("Relatics_XML.xml")
root = tree.getroot()
print(root.tag)
print(root.attrib)
namespaces = {"soap": "http://www.w3.org/2003/05/soap-envelope/",
"xsi": "http://www.w3.org/2001/XMLSchema-instance",
"xsd": "http://www.w3.org/2001/XMLSchema/",
'a': 'http://www.relatics.com/',}
names = tree.findall('./soap:Body''/a:GetResultResponse''/a:GetResultResult', namespaces)
print(names)
for name in names:
print(name.text)
i tried different methods like find and findall and also inside the method i try to pass different values but all its printing is null.
I'm not sure how to get the values out of tags.
Using xml.etree.ElementTree make life easier.
documentation in here
It can parsing tag attribute or innerText.

If you using xml file open, using this code
with open('data.xml', 'r') as xml_file:
root = ET.parse(xml_file)

get default value if don't find elements with iterfind

I have these code to extract of xml file some elements:
for general in tree.iter('FOLDER'):
nameFolder = general.attrib.get('FOLDER_NAME')
for job_nodeOS in tablaGeneral.iterfind(".//JOB[#APPL_TYPE='OS']"):
listaOS.clear()
listaOS.append(job_name)
listaOS.append(nameFolder)
listaOS.append(daily)
for job_nodeOS3 in job_nodeOS.iterfind("ON"):
listaOS.append(job_nodeOS3.get('STMT',"NO APLICA"))
listaOS.append(job_nodeOS3.get('CODE',"NO APLICA"))
for job_nodeOS4 in job_nodeOS3.iterfind("DOMAIL"):
listaOS.append(job_nodeOS5.get('SUBJECT',"NO APLICA"))
listaOS.append(job_nodeOS5.get('MESSAGE',"NO APLICA"))
for variable_name in variablesOS:
variable_node = job_nodeOS.find(f"./VARIABLE[#NAME='{variable_name}']")
variable_value = variable_node.get("VALUE", default_value) if variable_node is not None else default_value
#print(job_name, variable_name.lstrip("%"), "=", variable_value)
listaOS.append(variable_value)
My problem is that if the clause for don't find any occurrences, I need listaOS add default values ('NO APLICA').

How do you properly fetch from this nested XML?

I have the following XML:
<?xml version="1.0" encoding="UTF-8"?>
<data>
<columns>
<Leftover index="5">Leftover</Leftover>
<NODE5 index="6"></NODE5>
<NODE6 index="7"></NODE6>
<NODE8 index="9"></NODE8>
<Nomenk__Nr_ index="2">Nomenk.
Nr.</Nomenk__Nr_>
<Year index="8">2020</Year>
<Name index="1">Name</Name>
<Value_code index="3">Value code</Value_code>
</columns>
<records>
<record index="1">
<Leftover>Leftover</Leftover>
<NODE5>Test1</NODE5>
<NODE6>Test2</NODE6>
<NODE8>Test3</NODE8>
<Nomenk__Nr_></Nomenk__Nr_>
<Name></Name>
<Value_code></Value_code>
</record>
... (it repeats itself with different values and the index value increments)
My code is:
import lxml
import lxml.etree as et
xml = open('C:\outputfile.xml', 'rb')
xml_content = xml.read()
tree = et.fromstring(xml_content)
for bad in tree.xpath("//records[#index=\'*\']/NODE5"):
bad.getparent().remove(bad) # here I grab the parent of the element to call the remove directly on it
result = (et.tostring(tree, pretty_print=True, xml_declaration=True))
f = open( 'outputxml.xml', 'w' )
f.write( str(result) )
f.close()
What I need to do is to remove the NODE5, NODE6, NODE8. I tried using a wildcard and then specifying one of the nodes (see line 6) but that seems to not have worked... I'm also getting a syntax error right after the loop on the first character but the code executes.
My problem is also that the encoding by lxml is set to ASCII afterwards when the file is "exported".
UPDATE
I am getting this error on line 8:
return = ...
^
SyntaxError: invalid syntax
I took some code from https://stackoverflow.com/a/7981894/1987598

Increasing Version in xml file using python script

/* Python Script */
import xml.etree.ElementTree as ET
tree = ET.parse('config.xml')
root = tree.getroot()
updateData = open('config.xml','w+')
print('Root Data is ',root.tag)
print('Root Attribute ',root.attrib)

Once the script gets executed the version number is increased by 1 which i was trying to achieve. But, ns0 tag is added throughout the file and the header XML info tag gets removed [].
Please let me know what i have done wrong.
Your script slightly modified:
import xml.etree.ElementTree as ET
ET.register_namespace('', 'http://www.w3.org/ns/widgets')
tree = ET.parse('config.xml')
# (...) no changes in this part of code.
tree.write(f, xml_declaration=True, encoding="utf-8")
updateData.close()
The result:
<?xml version='1.0' encoding='utf-8'?>
<widget xmlns="http://www.w3.org/ns/widgets" id="io.ionic.starter" version="0.0.2">
<name>aman</name>

One of the namespace declarations has been dropped because it was not used in the XML body.
If you want to preserve namespaces use lxml library. In this case, your code would look like this (notice no ET.register_namespace):
import lxml.etree as ET
tree = ET.parse('config.xml')
root = tree.getroot()
updateData = open('config.xml','w+')
# (...) no changes in this part of code.
tree.write(f, xml_declaration=True, encoding="utf-8")
updateData.close()
In this case the output:
<?xml version='1.0' encoding='UTF-8'?>

Import NetworkX generated GraphML data to Gephi

I am trying to import the data from a graphml file into Gephi but the attributes are not loaded properly.
An example of this problem (with only one node and no edges):
<?xml version='1.0' encoding='utf-8'?>
<graphml xmlns="http://graphml.graphdrawing.org/xmlns" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://graphml.graphdrawing.org/xmlns http://graphml.graphdrawing.org/xmlns/1.0/graphml.xsd">
<key attr.name="g" attr.type="long" for="edge" id="d10" />
<key attr.name="r" attr.type="long" for="edge" id="d9" />
<key attr.name="b" attr.type="long" for="edge" id="d8" />
<key attr.name="g" attr.type="long" for="node" id="d7" />
<key attr.name="b" attr.type="long" for="node" id="d6" />
<key attr.name="y" attr.type="double" for="node" id="d5" />
<key attr.name="size" attr.type="double" for="node" id="d4" />
<key attr.name="r" attr.type="long" for="node" id="d3" />
<key attr.name="x" attr.type="double" for="node" id="d2" />
<key attr.name="z" attr.type="double" for="node" id="d1" />
<key attr.name="label" attr.type="string" for="node" id="d0" />
<graph edgedefault="undirected">
<node id="Node 1">
<data key="d0">Node 1</data>
<data key="d1">0.0</data>
<data key="d2">-430.34348</data>
<data key="d3">255</data>
<data key="d4">10.0</data>
<data key="d5">-32.351364</data>
<data key="d6">0</data>
<data key="d7">0</data>
</node>
</graph>
</graphml>
Note: the file is generated by networkx so I do not have too much control over the order of the attributes
Once I import this file into Gephi, when I inspect the attributes I see that:
size = 4
x,y,z = (0,0,0)
r,g,b = (0,0,0)
Id = Node 1
Label = 255
If I run the same code again (and NetworkX will write the keys in different order) other other attributes will be read incorrectly)
For generating the graphml I use something like:
nodeid = 'Node 1'
G = nx.Graph()
G.add_node(nodeid)
G.node[nodeid]['label'] = nodeid
G.node[nodeid]['size'] = 4
G.node[nodeid]['x'] = -430.34348
G.node[nodeid]['y'] = -32.351364
G.node[nodeid]['z'] = 0.0
G.node[nodeid]['r'] = 255
G.node[nodeid]['g'] = 0
G.node[nodeid]['b'] = 0
nx.write_graphml(G, 'test.graphml')
Is there a way to:
1) convince Gephi to load the attributes correctly
2) convince NetworkX to write (in the graphml file) the attributes alphabetically sorted ?
The above described issue was was confirmed as a bug and was fixed in the Gephi 0.9.2 release.
