I am working on XML-Parsing and I want to get the attribute of a sepcific value.
I have a XML-file (see bellow) and I want to get the value of val in the second line after lid="diagnosticEcgSpeed" which is -1.
<global>
<setting lid="diagnosticEcgSpeed" val="-1" pers="" res="" unit="mm/s">
<txt id="001041" description="" type="">Geschwindigkeit</txt>
<value lid="1" val="-1" text="50"/>
<value lid="2" val="-2" text="25"/>
<value lid="4" val="-4" text="12,5"/>
<!-- todo: only one value is needed -> use adult value -->
<preset i="-1" c="-1" a="-1" />
</setting>
<setting lid="diagnosticEcgScale" val="10" unit="mm/mV" pers="" res="">
<txt id="001040" description="" type="">Amplitudenskalierung</txt>
<value lid="2" val="2" />
<value lid="5" val="5" />
<value lid="10" val="10" />
<value lid="20" val="20" />
<!-- todo: only one value is needed -> use adult value -->
<preset i="10" c="10" a="10" />
</setting>
</global>
I tried so far this code:
import xml.etree.ElementTree as ET
tree = ET.parse('basics.xml')
root = tree.getroot()
y=root.find(".//*[#lid='diagnosticEcgSpeed']").attrib['val']
print(y)
And the return is
Traceback (most recent call last):
File "parsing_example.py", line 5, in <module>
y=root.find(".//*[#lid='diagnosticEcgSpeed']").attrib['val']
KeyError: 'val'
I don't understand what my error is to get my value var.
You can use the following xpath: .//setting[#lid='diagnosticEcgSpeed'] to retrieve the element and then retrieve its attribute.
See the example below:
data = """
<global>
<setting lid="diagnosticEcgSpeed" val="-1" pers="" res="" unit="mm/s">
<txt id="001041" description="" type="">Geschwindigkeit</txt>
<value lid="1" val="-1" text="50"/>
<value lid="2" val="-2" text="25"/>
<value lid="4" val="-4" text="12,5"/>
<!-- todo: only one value is needed -> use adult value -->
<preset i="-1" c="-1" a="-1" />
</setting>
</global>
"""
import xml.etree.ElementTree as ET
tree = ET.fromstring(data)
y=tree.find(".//setting[#lid='diagnosticEcgSpeed']").attrib["val"]
print(y)
In your case if you want to extract this value directly from a file you can use the following:
import xml.etree.ElementTree as ET
tree = ET.parse('./basics.xml')
y=tree.find(".//setting[#lid='diagnosticEcgSpeed']").attrib['val']
print(y)
Which output:
-1

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:

I am new with python and I am looking for advices on what is the best approach to do the following task:
I have an xml file looking like this
<component xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.spiritconsortium.org/XMLSchema/SPIRIT/1685-2009 http://www.spiritconsortium.org/XMLSchema/SPIRIT/1685-2009/index.xsd">

I want to do some modifications to modify the node of "reset" to become 2 separate nodes, one for "resetValue" and another "resetMask" but keeping same data in "value" and "mask" extracted into "resetValue" and "resetMask" as follow:
........
<access>read-write</access>
<resetValue>0x00000002</resetValue>
<resetMask>0xFFFFFFFF</resetMask>
<field>
.............
I managed the part of parsing my xml file with success, now I can't know how to start this first modification.
Thank you to guide me.

I have an xml file as below:
<?xml version="1.0" encoding="utf-8"?>
<EDoc CID="1000101" Cname="somename" IName="iname" CSource="e1" Version="1.0">
<RIGLIST>

<nodeA nodeAID="1000023" nodeAName="node3B" nodeAExtID="9000023" />
</ListID>
</RIG>
</RIGLIST>
</EDoc>
I need to search for the Node value RIGName and if match is found print out all the values of nodeAName
Example:
Searching for RIGName = "RgName2" should print all the values as node1B, node2B, node3B
As of now I am only able to get the first part as below:
import xml.etree.ElementTree as eT
import re
xmlfilePath = "Path of xml file"
tree = eT.parse(xmlfilePath)
root = tree.getroot()
for elem in root.iter("RIGName"):
# print(elem.tag, elem.attrib)
if re.findall(searchtxt, elem.attrib['RIGName'], re.IGNORECASE):
print(elem.attrib)
count += 1
How can I get only the immediate child node values?
Switching from xml.etree to lxml would give you a way to do it in a single go because of a much better XPath query language support:
In [1]: from lxml import etree as ET
In [2]: tree = ET.parse('input.xml')
In [3]: root = tree.getroot()
In [4]: root.xpath('//RIG[#RIGName = "RgName2"]/ListID/nodeA/#nodeAName')
Out[4]: ['node1B', 'node2B', 'node3B']
I have xml file as following:
<plugin-config>
<properties>
<property name="AZSRVC_CONNECTION" value="diamond_plugins#AZSRVC" />
<property name="DIAMOND_HOST" value="10.0.230.1" />
<property name="DIAMOND_PORT" value="3333" />
</properties>
<pack-list>
<vsme-pack id="monthly_50MB">
<campaign-list>
<campaign id="2759" type="SOB" />
<campaign id="2723" type="SUBSCRIBE" />
</campaign-list>
</vsme-pack>
<vsme-pack id="monthly_500MB">
<campaign-list>
<campaign id="3879" type="SOB" />
<campaign id="3885" type="SOB" />
<campaign id="2724" type="SUBSCRIBE" />
<campaign id="1111" type="COB" /></campaign-list>
</vsme-pack>
</pack-list>
</plugin-config>
And trying to run this Python script to remove 'campaign' with specific id.
import xml.etree.ElementTree as ET
tree = ET.parse('pack-assign-config.xml')
root = tree.getroot()
pack_list = root.find('pack-list')
camp_list = pack_list.find(".//vsme-pack[#id='{pack_id}']".format(pack_id=pack_id)).find('campaign-list').findall('campaign')
for camp in camp_list:
if camp.get('id') == '2759':
camp_list.remove(camp)
tree.write('out.xml')
I run script but out is the same as input file, so does not remove element.
Issue :
this is wrong way to find the desired node . you are searching for vsme-pack and the trying to find campaign-list and campaign ? which incorrect format.
camp_list = pack_list.find(".//vsme-pack[#id='{pack_id}']".format(pack_id=pack_id)).find('campaign-list').findall('campaign')
Fixed Code Example
here is the working code which removes the node from xml
import xml.etree.ElementTree as ET
root = ET.parse('pack-assign-config.xml')
# Alternatively, parse the XML that lives in 'filename_path'
# tree = ElementTree.parse(filename_path)
# root = tree.getroot()
# Find the parent element of each "weight" element, using XPATH
for parent in root.findall('.//pack-list/'):
# Find each weight element
for element in parent.findall('campaign-list'):
for camp_list in element.findall('campaign'):
if camp_list.get('id') == '2759' or camp_list.get('id') == '3879' :
element.remove(camp_list)
root.write("out.xml")
hope this helps
I'm trying to parse the following xml file:
<?xml version="1.0" encoding="UTF-8"?>
<gexf xmlns="http://www.gexf.net/1.2draft" version="1.2">
<graph mode="static" defaultedgetype="directed">
<nodes>
<node id="0" label="Hello" />
<node id="1" label="Word" />
<node id="2" />
</nodes>
<edges>
<edge id="0" source="0" target="1" />
<edge id="1" source="1" target="2" weight="2.0" />
</edges>
</graph>
</gexf>
As can be seen some edges have weights, some do not.
My code is like the following:
elif name == "edge":
u = attrs.getValue("source")
v = attrs.getValue("target")
w = attrs.getValue("weight")
if w is not None:
self.edgeweight = w
Here I expect w to be None on the first line and 2.0 on the second line of the XML file. Instead all I get is an error. What's the proper way to control this?
get() method did the trick.
w = attrs.get("weight")
if w is not None:
self.weighted = True
self.edgeweight = float(w)
Try the following.
if attrs.hasKey("weight"):
w = attrs.getValue("weight")
self.edgeweight = w
I used this as reference. It doesn't specify if you can use "weight" in attrs, but you can try and see if it works.
