python - insert list of elements in loop inside element builder in lxml

Question

I have a XML body which was constructed using lxml.etree.E module. It looks like this -

E.TAGA(
    E.TAGB(
        E.TAGC(
            ...list goes here...
        )
    )
)

This method of construction cannot be altered.

I have a list of strings ["textA", "textB", "textC"] which have to be added to the xml under TAGC (as shown above) with each entry wrapped inside another tag TAGD. I have tried using fromStringlist but it doesn't work. Please help. Hope my question is clear.

This is how the final XML code should appear -

E.TAGA(
    E.TAGB(
        E.TAGC(
            E.TAGD(textA),
            E.TAGD(textB),
            E.TAGD(textC)
        )
    )
)

Here is the desired output -

<TAGA>
    <TAGB>
        <TAGC>
            <TAGD>textA</TAGD>
            <TAGD>textB</TAGD>
            <TAGD>textC</TAGD>
        </TAGC>
    </TAGB>
</TAGA>

Answer 1

below (using core python XML lib)

import xml.etree.ElementTree as ET

d_data = ['T1', 'T2', 'T3']

a = ET.Element('A')
b = ET.SubElement(a, 'B')
c = ET.SubElement(b, 'C')
for text in d_data:
    temp = ET.SubElement(c, 'D')
    temp.text = text
ET.dump(a)

output

<?xml version="1.0" encoding="UTF-8"?>
<A>
   <B>
      <C>
         <D>T1</D>
         <D>T2</D>
         <D>T3</D>
      </C>
   </B>
</A>
