Editing EPG XML with Python

I am new to Python and looking to modify an XML file to change some things around. I can provide an example followed by what I would like the output to be.

Create a series tag for multiple episodes - XML to XSLT

I have an XML feed with multiple tv show's episodes.
I need to convert it into an RDF/XML file using XLST template.
Each RDF should be one tv show, its episodes should be nested properties under it along with extracted info about the show.
The way i'm transforming it, all episodes (item tag) become RDFs.
How do i extract tv show's metadata from episode i.e items and then nest the tv show's episodes under the tv show rdf?
CURRENT BEHAVIOUR
rdf:Group rdf:id=New Item in Series
ebucore:groupName: Football
ebucore:Season: 1
　ebucore:Episode: 1
　ebucore:groupId: Better Call Saul
　ebucore:groupDescription: Three young up
#----------------------------------------------------------------------
rdf:Group rdf:id=New Item in Series
ebucore:groupName: Basketball
ebucore:Season: 1
　ebucore:Episode: 2
　ebucore:groupId: Better Call Saul
　ebucore:groupDescription: Three young up
#----------------------------------------------------------------------
EXPECTED BEHAVIOUR IS BELOW
Each show as an rdf with its episodes nested properties under it.
rdf
show title better call saul
show description: Three young up
ep
ep.id 1
ep
ep.id 2

Change the XML structure to a new one with python

I want to change the structure from an XML to another standard structure given to me.
I believe I can achieve that through the following steps:
Get all the tags and their attributes, so I can know what to modify,
remove or add.
Change the tags name (i.e. informaltable to table, or , sect1 to
section)
Establish certain standard attributes for the different tags, and
show it in a dictionary (i.e. all the section, title and table tags
must have these attributes ----
section:{"xmlns:xsi","id","type","xsi:noNamespaceSchemaLocation"} ,
title:"id" , table:{"frame","id"} .
Give a random alpha-numerical id to every tag that has the id
attribute and it must never repeat itself(i.e.
id=id-824fc56b-431b-4ad3-e933-f0fc222e50d3)
Modify, add and remove attributes values for certain tags (i.e.
frame was frame=all and now is frame=any) (i.e. delete the rowsep
attribute in the colspec tag).
Remove specific tags(i.e. remove the anchor tags and of course all
of their attributes) (I hope this doesn't affect the whole
hierarchy).
I have this xml example
<section xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" id="id-c3ee53e4-e2ef-441b-8f3b-7320c4e32ef8" type="policy" xsi:noNamespaceSchemaLocation="urn:fontoxml:cpa.xsd:5.0">

And this is the code that I have so far
from lxml import etree
import numpy as np
#Parsing the xml file and creating lists
tree = etree.parse("InitialFile")
root = tree.getroot()
Lista = []
tags = []
#Get the unique tags values
for element in root.iter():
Lista.append(element.tag)
tags = np.unique(Lista)
#Show the unique tag[attributes] pairs
for tag in tags:
print(tag,root.xpath(f'//{tag}')[0].attrib.keys())
#Changes the tag name to the required's tag's name
for p in tree.findall(".//sect1"):
p.tag = ("section")
for p in tree.findall(".//informaltable"):
p.tag = ("table")
#Modify the tag's attributes to its desired form
for cy in root.xpath('//section'):
cy.attrib['xmlns:xsi']='http://www.w3.org/2001/XMLSchema-instance' #it doesnt accept : as part of the attribute's name and i don't know why
cy.attrib['id']=random() #this doesn't work yet
cy.attrib['type']='policy'
cy.attrib['xsi:noNamespaceSchemaLocation']='urn:fontoxml:cpa.xsd:1.0'#it doesnt accept :as part of the attribute's name and i don't know why
#Modify the attributes values
for t in root.xpath('//title'):
t.attrib['id']='random()
for p in root.xpath('//section'):
p.attrib['id']=random()
p.attrib['type']='policy'
for p in root.xpath('//table'):
p.attrib['id']=random()
for ct in root.xpath('//colspec'):
ct.attrib.pop("rowsep", None)
#Print the new xml to make sure it worked:
print(etree.tostring(root).decode())
tree.write("Final file.xml")
If you have any other ideas please feel free to share.

I agree that this is a task for XSLT (which can be used by lxml), here is an example stylesheet that tries to implement some of your requirements in a modular way by delegating each change to a template of its own:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
version="1.0">
<xsl:output method="xml"/>
<xsl:template match="#* | node()">
<xsl:copy>
<xsl:apply-templates select="#* | node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="sect1">
<section>
<xsl:apply-templates select="#* | node()"/>
</section>
</xsl:template>
<xsl:template match="informaltable">
<table>
<xsl:apply-templates select="#* | node()"/>
</table>
</xsl:template>
<xsl:template match="#id">
<xsl:attribute name="{name()}">
<xsl:value-of select="generate-id()"/>
</xsl:attribute>
</xsl:template>
<xsl:template match="#xsi:noNamespaceSchemaLocation">
<xsl:attribute name="{name()}" namespace="{namespace-uri()}">urn:fontoxml:cpa.xsd:1.0</xsl:attribute>
</xsl:template>
<xsl:template match="colspec/#rowsep"/>
</xsl:stylesheet>

I hope with that as a starting point and any XSLT tutorial or introduction you can work it out.

How to convert nodes in XML to CDATA with XSLT?

I have a source.xml file with structure like:
<products>
<product>
<id>1</id>
<description>
<style>
table{
some css here
}
</style>
<descr>
<div>name of producer like ABC&DEF</div>

<th>parameters</th>
<tr><td>name of param 1 e.g POWER CONSUMPTION</td>
<td>value of param 1 with e.g < 100 W</td></tr>
</table>
</descr>
</description>
</product>
.....................
</products>
I would like to have:

transform = ET.XSLT(xslt)
newdoc = transform(doc)
with open(f'output.xml', 'wb') as f:
f.write(newdoc)
on SublimeText3 I allways get the same error:
lxml.etree.XMLSyntaxError: StartTag: invalid element name, {number of line and column with first appearance of illegal character}
I am sure, that solution is straight in front of me in links above, but I can't see it.
Or maybe I can't find it because I can't ask the right question. Please help, I'm new to coding.

The input XML is not well-formed. I had to fix it first. That seems to be the reason why it is failing on your end.

In my view a clean way is to make use of a serialize function to serialize all elements you want as plain text, to then designate the parent container in the xsl:output declaration in the cdata-section-elements and to finally make sure the XSLT processor is in charge of the serialization.
Now XSLT 3 has a built-in XPath 3.1 serialize function, in Python you could use that with Saxon-C and its Python API.
For libxslt based XSLT 1 with lxml you can write an extension function in Python exposed to XSLT:
from lxml import etree as ET
def serialize(context, nodes):
return b''.join(ET.tostring(node) for node in nodes)
ns = ET.FunctionNamespace('http://example.com/mf')
ns['serialize'] = serialize
xml = ET.fromstring('<root><div><p>foo</p><p>bar</p></div></root>')
xsl = ET.fromstring('''<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:mf="http://example.com/mf" version="1.0">
<xsl:output method="xml" cdata-section-elements="div" encoding="UTF-8"/>
<xsl:template match="#* | node()">
<xsl:copy>
<xsl:apply-templates select="#* | node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="div">
<xsl:copy>
<xsl:value-of select="mf:serialize(node())"/>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>''')
transform = ET.XSLT(xsl)
result = transform(xml)
result.write_output("transformed.xml")
Output then is
<?xml version="1.0" encoding="UTF-8"?>
<root><div><![CDATA[<p>foo</p><p>bar</p>]]></div></root>

xslt transformation works in Altova but not in python

I am trying to transform the one xml to another xml using xslt. Below is the xslt I am using
<?xml version="1.0"?>
<xsl:stylesheet version="1.0" xmlns="Apartments.AP.Mits20PropertyFinal"

<xsl:output method="xml" encoding="UTF-8" indent="yes"/>
<xsl:key name="myKey" match="ILS_Unit/Units/Unit" use="./Identification[#IDType='FloorplanID']/#IDValue"/>
<xsl:template match="/">

The transformation works fine using altova tool but does not work in python.
Below is the python script I am using.
from lxml import etree
import os
import glob
xslt = etree.parse("fl.xslt")
dom = etree.parse("f.xml",)
transform = etree.XSLT(xslt)
try:
newdom = transform(dom)
root = etree.parse(newdom)
properties = root.findall("./Property")
print(properties)
except Exception as e:
print (e)
for error in transform.error_log:
print(error.message, error.line)
print(etree.tostring(newdom, pretty_print=True))
I am trying to print the property nodes and I also tried to write the result to .xml file but it returns nothing. Could some one tell what the issue could be.
Surprisingly it works fine in Altova.
Below are the errors that are thrown.
line 53, in <module>
root = etree.parse(newdom)
File "src\lxml\etree.pyx", line 3519, in lxml.etree.parse
File "src\lxml\parser.pxi", line 1862, in lxml.etree._parseDocument
TypeError: cannot parse from 'lxml.etree._XSLTResultTree'

Specific error has nothing to do with XSLT but your attempted parse of the result. Like Python's built-in xml.etree, the parse function of lxml.etree requires a file-like object. However, the result from an XSLT transformation in lxml is a ElementTree object that you can then directly run any XML DOM calls like findall, iterfind, etc.
Therefore, simply remove the parse line. Additionally, because you have a default namespace, consider assigning a temporary prefix to access nodes. Also, consider xpath in lxml.
newdom = transform(dom)
properties = newdom.findall("./doc:Property", namespaces={'doc': 'Apartments.AP.Mits20PropertyFinal'})
print(properties)
# [<Element {Apartments.AP.Mits20PropertyFinal}Property at 0x136b2f94b08>]
properties = newdom.xpath("./doc:Property", namespaces={'doc': 'Apartments.AP.Mits20PropertyFinal'})
print(properties)
# [<Element {Apartments.AP.Mits20PropertyFinal}Property at 0x136b2f94b08>]
Output
print(etree.tostring(newdom, pretty_print=True).decode("utf-8"))
