Strange error occured, got a XML-file emailed to me which was wrongly formated. The info in the file was all in one row.
Like this
<?xml version="1.0" encoding="UTF-8" standalone="yes"?><Text><otherText><printdate>2015-02-08</printdate>
Does anyone know a quick way to fix this by using a python script or something that has had the same error?
I want to make the file like this.
<?xml version="1.0" encoding="ISO-8859-1"?>
<Text>
<OtherText>
<Name>VH2</Name>
<PrintDate>2015-02-05</PrintDate>
Thanks!
It seems you want to print pretty, if you look into other XML libraries, such as lxml, it support pretty print.
import lxml.etree as etree
x = etree.parse("filename")
print etree.tostring(x, pretty_print = True)
However, you can also try this:
Pretty printing XML in Python
If the XML is well formed this snippet will work
#!/usr/bin/python
import xml.dom.minidom
def main():
ugly_xml = open('ugly.xml', 'r')
pretty_xml = open('pretty.xml', 'w')
xmll = xml.dom.minidom.parseString(ugly_xml.read())
pretty_xml.write(xmll.toprettyxml())
if __name__ == "__main__":
main()

I have some variables in Python that I need to store as XML. I have been using the python:LXML module for this so far. Not too experienced with it. Have tried playing around with various tutorials and docs, but I am at a dead end need some help.
Here is the python script:
root = etree.Element("root")
coins=etree.Element("coins")
doc=etree.ElementTree(coins)
coins.append(etree.Element("trader"))
coins.append(etree.Element("metal"))
coins.append(etree.Element("type"))
coins.append(etree.Element("price"))
coins[0].text="Gold.co.uk"
coins[0].attrib["variable"]=("GLDAG_MAPLE")
coins[1].text="Silver"
coins[2].text="Britannia"
coins[3].text=str(GLDAG_MAPLE)
doc.write('data.xml', pretty_print=True)
As of now it outputs this:
<coins>
<trader variable="GLDAG_MAPLE">Gold.co.uk</trader>
<metal>Silver</metal>
<type>Britannia</type>
<price>
£31.20
</price>
</coins>
However I would like it to look like this:
<root>
<coin>
<trader> Gold.co.uk </trader>
<type> Britannia </type>
<price> £31.20 </price>
</coin>
</root>
The tags and their sub-tags would be duplicated for every type of coin. I have no idea how to construct the XML so that the output looks like the third code-block. So far I have tried to follow other scripts that I have seen on github and other sites but modify them to suit my needs but my scripts keep failing or producing incorrect resaults for some reason.
If someone could help me out then that would be great!
You can simply append the Element to root:
from lxml import etree
coinItems = [
{'trader': 'Gold.co.uk', 'metal': 'Silver', 'type': 'Britannia'},
{'trader': 'copper.co.uk', 'metal': 'Copper', 'type': 'World'}
]
root = etree.Element("root")
for ci in coinItems:
coin=etree.Element("coin")
etree.SubElement(coin, "trader", {'variable': 'GLDAG_MAPLE'}).text = ci['trader'] # example how to use attributes!
etree.SubElement(coin, "metal").text = ci['metal']
etree.SubElement(coin, "type").text = ci['type']
root.append(coin)
fName = '/tmp/data.xml'
with open(fName, 'wb') as f:
# remove encoding here, in case you want escaped ASCII characters: £
f.write(etree.tostring(root, xml_declaration=True, encoding="utf-8", pretty_print=True))
print(open(fName).read())
Output:
<?xml version='1.0' encoding='utf-8'?>
<root>
<coin>
<trader variable="GLDAG_MAPLE">Gold.co.uk</trader>
<metal>Silver</metal>
<type>Britannia</type>
</coin>
<coin>
<trader variable="GLDAG_MAPLE">copper.co.uk</trader>
<metal>Copper</metal>
<type>World</type>
</coin>
</root>
I prefer using the lxml builder (https://lxml.de/api/lxml.builder.ElementMaker-class.html) because imho it is easier to see the structure of your XML document.
from lxml.builder import E
root = E.root(
E.coin(
E.trader("Gold.co.uk",
variable="GLDAG_MAPLE"),
E.metal("silver"),
E.price("£31.20")
)
)
You can then append the root element to your main document.
I have an XML file which has many elements. I would like to create a list/array of all the values which have a specific element name, in my case "pair:ApplicationNumber".
I've gone over a lot of the other questions however I am not able to find an answer. I know that I can do this by loading the text file and going over it using pandas however, I'm sure there's a much better way.
I was unsuccessful trying ElementTree as well as XML.Dom using minidom
My code currently looks as follows:
import os
from xml.dom import minidom
WindowsUser = os.getenv('username')
XMLPath = os.path.join('C:\\Users', WindowsUser, 'Downloads', 'ApplicationsByCustomerNumber.xml')
xmldoc = minidom.parse(XMLPath)
itemlist = xmldoc.getElementsByTagName('pair:ApplicationNumber')
for s in itemlist:
print(s.attributes['pair:ApplicationNumber'].value)
an example XML file looks as follows:
<?xml version="1.0" encoding="UTF-8"?>

The XML in your example is expanding the "pair:" part of the tags according to the schema you've used, so it doesn't match 'pair:ApplicationNumber', even though it looks like it should.
I've used element tree to extract the application numbers as follows (I've just used a local XML file in my examples, rather than the full path in your code)
Example 1:
from xml.etree import ElementTree
tree = ElementTree.parse('ApplicationsByCustomerNumber.xml')
root = tree.getroot()
for item in root:
if 'ApplicationStatusData' in item.tag:
for child in item:
if 'ApplicationNumber' in child.tag:
print child.text
Example 2:
from xml.etree import ElementTree
tree = ElementTree.parse('ApplicationsByCustomerNumber.xml')
root = tree.getroot()
for item in root.iter('{urn:us:gov:uspto:pair}ApplicationStatusData'):
for child in item.iter('{urn:us:gov:uspto:pair}ApplicationNumber'):
print child.text
Hope this may be useful.

I wrote the following code to try and process it:
from lxml import etree
import pdb
f = open('/vagrant/out2.xml', 'r')
xml_str = f.read()
xml_doc = etree.fromstring(xml_str)
f.close()
From what I understand from the lxml xpath docs, I should be able to get the text from a specific element as follows:
xml_doc.xpath('/metadata/codeBook/docDscr/citation/titlStmt/titl/text()')
However, when I run this it returns an empty array.
The only xpath I can get to return something is using a wildcard:
xml_doc.xpath('*')
Which returns [<Element {ddi:codebook:2_5}codeBook at 0x7f8da8a413f8>].
I've read through the docs and I'm not understanding what is going wrong with this. Any help is appreciated.
You need to take the default namespace into account so instead of
xml_doc.xpath('/metadata/codeBook/docDscr/citation/titlStmt/titl/text()')
use
xml_doc.xpath.xpath(
'/oai:metadata/ddi:codeBook/ddi:docDscr/ddi:citation/ddi:titlStmt/ddi:titl/text()',
namespaces={
'oai': 'http://www.openarchives.org/OAI/2.0/',
'ddi': 'ddi:codebook:2_5'
}
)
I'm trying to generate an xml that looks exactly like this:
<?xml version="1.0" encoding="utf-8"?>

<channelsDepth type="uint">16</channelsDepth>
<channelsEncoding type="string">Float</channelsEncoding>
<channelsEndianess type="string">Little Endian</channelsEndianess>
<fieldDominance type="int">2</fieldDominance>
<height type="uint">1080</height>
<nbChannels type="uint">4</nbChannels>
<pixelLayout type="string">ABGR</pixelLayout>
<pixelRatio type="float">1</pixelRatio>
<rowOrdering type="string">up</rowOrdering>
<width type="uint">1920</width>
</format>
</XML>
It's part of a VFX nodal workflow script ensemble and this file is part of a "read media" node.
I've spent the whole week looking at many different things but can't find anything close to this. I picked lxml for the pretty print thing. I was able to generate a bunch of other simpler (to me) xml files but for this one, I gotta say … i'm lost. Complete fail so far!
Could someone kindly shed a light on this please?
MY QUESTIONS:
- is lxml appropriate for this?
- if no, what is a better choice? (i did look for ElementTree example, no luck!)
- if yes, where do i start? Could someone share a piece a code to get me started?
What i could create so far was things like this one:
import os, sys
import lxml.etree
import lxml.builder as lb
from lxml import etree
E = lxml.builder.ElementMaker()
Setup = E.Setup
Base = E.Base
Version = E.Version
Note = E.Note
Expanded = E.Expanded
ScrollBar = E.ScrollBar
Frames = E.Frames
Current_Time = E.Current_Time
Input_DataType = E.Input_DataType
ClampMode = E.ClampMode
AdapDegrad = E.AdapDegrad
UsedAsTransition = E.UsedAsTransition
State = E.State
root_node = Setup(
Base(
Version('12.030000'),
Note(''),
Expanded('False'),
ScrollBar('0'),
Frames('0'),
Current_Time('1'),
Input_DataType('3'),
ClampMode('0'),
AdapDegrad('False'),
UsedAsTransition('False')
),
State(),
)
print lxml.etree.tostring(root_node, pretty_print=True)
str = etree.tostring(root_node, pretty_print=True)
myXMLfile = open('/Users/stefan/XenDRIVE/___DEV/PYTHON/Create_xlm/create_Batch_xml_setups/result/xml_result/root.root_node.xml', 'w')
myXMLfile.write(str)
myXMLfile.close()
Hope those are "acceptable" questions.
Thank you in advance for any help.
First, make the format node and then add it to the root XML node.
Example code (follow it to create more nodes):
from lxml import etree
from lxml.builder import ElementMaker
E = ElementMaker()
format = E.format(
E.type("video"),
E.channelsDepth("16", type="uint"),
# create more elements here
type="format",
uid="BEAUTY:MasterBeauty"
)
root = E.XML(
format,
type="formats",
version="4"
)
print(etree.tostring(root, xml_declaration=True, encoding='utf-8', pretty_print=True))
Prints:
<?xml version='1.0' encoding='utf-8'?>
<XML version="4" type="formats">
<format type="format" uid="BEAUTY:MasterBeauty">
<type>video</type>
<channelsDepth type="uint">16</channelsDepth>
</format>
</XML>

this is what I have been using
import xml.etree.ElementTree as ET
data = ET.fromstring(content)
versioninfo = data.findall("VersionInfo/Version")
print len(versioninfo)
print versioninfo.text
however this gives a blank output...any suggestions?
Try this:
import xml.etree.ElementTree as ET
data = ET.fromstring(content)
versioninfo = data.find(
"ns:VersionInfo/ns:Version",
namespaces={'ns':'http://www.vmware.com/vcloud/versions'})
print versioninfo.text
Use .find(), not .findall() to return a single element
Your XML uses namespaces. The full path to your desired object is: '{http://www.vmware.com/vcloud/versions}VersionInfo/{http://www.vmware.com/vcloud/versions}Version' By passing in the namespaces parameter, you are able to use the shortcut syntax: ns:VersionInfo/ns:Version.
