BeautifulSoup works fine for attached example, bt unfortunately not on a big XML with different grouped XML-Tags for Name, Age and Number which are the relevant text values. Is this somehow possible for the following example to read Name, Age and Number and write it to a new file?

<data>
<friends>
<human>
<Name>Tim</Name>
<Age>23</Age>
<Number>1234</Number>
</human>
<human>
<Name>Jenny</Name>
<Age>23</Age>
<Number>4321</Number>
</human>
<animal>
<Name>Wuff</Name>
<Age>4</Age>
<Number>2323</Number>
</animal>
</friends>
</data>

Thanks a lot.

Yes of course,you should try yourself
It's not so common to parse a whole XML file to text with tags names.

Use BBCode code tag,and a XML file usually have have indentation then is easier to the see structure.
Example:

<?xml version="1.0" encoding="UTF-8"?>
<data>
  <friends>
    <human>
      <Name>Tim</Name>
      <Age>23</Age>
      <Number>1234</Number>
    </human>
    <human>
      <Name>Jenny</Name>
      <Age>23</Age>
      <Number>4321</Number>
    </human>
    <animal>
      <Name>Wuff</Name>
      <Age>4</Age>
      <Number>2323</Number>
    </animal>
  </friends>
</data>

So it a read this file and do some test.

from bs4 import BeautifulSoup

soup = BeautifulSoup(open('test.xml'), 'lxml')

Test:

>>> for tag in soup.find_all('human'):
...     for item in tag.find_all(['name', 'age', 'number']):
...         print(item)
...         
<name>Tim</name>
<age>23</age>
<number>1234</number>
<name>Jenny</name>
<age>23</age>
<number>4321</number>

This get all under human,so if use friends will get both human/animal.

>>> for tag in soup.find_all('friends'):
...     for item in tag.find_all(['name', 'age', 'number']):
...         print(item)
...         
<name>Tim</name>
<age>23</age>
<number>1234</number>
<name>Jenny</name>
<age>23</age>
<number>4321</number>
<name>Wuff</name>
<age>4</age>
<number>2323</number>

So can look like this,write to file you can try yourself.

from bs4 import BeautifulSoup

soup = BeautifulSoup(open('test.xml'), 'lxml')
for tag in soup.find_all('friends'):
    for item in tag.find_all(['name', 'age', 'number']):
        print(f'{item.name.capitalize()}:{item.text}')

Output:
Name:Tim
Age:23
Number:1234
Name:Jenny
Age:23
Number:4321
Name:Wuff
Age:4
Number:2323

When I adapt and apply the last script for another big XML-File, then it's not coming over the firsts loop?

Yes for a bigger file you will probably need to make changes,so try that i don't know how it look

Thanks, but I was wondering me if there is a more generic way?

Is it possible to use a regex instead of 'human' 'animal', because in real file are blocks with Tags like <Param-One-Block> and <Param-Two-Block>. Means a RegEx for One and Two in middle, because the rest is always the same.

Quote:for tag in soup.find_all('friends'):

Algo:
Search for block with Regex and retrieve same subparameter (here Name, Age, Number) until EOF. Is this somehow possible?

<?xml version="1.0" encoding="UTF-8"?>
<data>
  <friends>
    <Param-One-Block>
      <Name>Tim</Name>
      <Age>23</Age>
      <Number>1234</Number>
    </Param-One-Block>
    <Param-One-Block>
      <Name>Jenny</Name>
      <Age>23</Age>
      <Number>4321</Number>
    </Param-One-Block>
    <Param-Two-Block>
      <Name>Wuff</Name>
      <Age>4</Age>
      <Number>2323</Number>
    </Param-Two-Block>
  </friends>
</data>

If you need all name,age and number trough the file,then find_all() with those parameter.
test1.xml your last code.

from bs4 import BeautifulSoup

soup = BeautifulSoup(open('test1.xml'), 'lxml')
for item in soup.find_all(['name', 'age', 'number']):
    print(f'{item.name.capitalize()}:{item.text}')

Output:
Name:Tim
Age:23
Number:1234
Name:Jenny
Age:23
Number:4321
Name:Wuff
Age:4
Number:2323
