I am programming novice and have just started learning python below is my xml file:

    <Build_details>
      <Release number="1902">
        <Build number="260">
          <OMS>
            <Build_path>ST_OMS_V1810_B340</Build_path>
            <Pc_version>8041.30.01</Pc_version>
          </OMS>
          <OMNI>
            <Build_path>ST_OMNI_V1810_B340</Build_path>
          </OMNI>
        </Build>
      </Release>
      <Release number="1810">
        <Build number="230">
          <OMS>
            <Build_path>ST_OMS_909908</Build_path>
            <Pc_version>8031.25.65</Pc_version>
          </OMS>
          <OMNI>
            <Build_path>ST_OMNI_798798789789</Build_path>
          </OMNI>
        </Build>
      </Release>
      <Release number="1806">
        <Build number="300">
          <OMS>
            <Build_path>ST_OMS_V18102_B300</Build_path>
            <Pc_version>8041.30.01</Pc_version>
          </OMS>
          <OMNI>

Here is the solution using python inbuilt library xml, You will have to find the release element first and then create a new build element and append to the release element.

import xml.etree.ElementTree as ET

if __name__ == "__main__":

    release_number = input("Enter the release number\n").strip()

    tree = ET.ElementTree(file="Build.xml") # Original XML File

    root = tree.getroot()

    for elem in root.iterfind('.//Release'):
        # Find the release element
        if elem.attrib['number'] == release_number:
            # Create new Build Element

            build_elem = ET.Element("Build", {"number": "123"})

            # OMS element
            oms_elem = ET.Element("OMS")
            build_path_elem = ET.Element("Build_path")
            build_path_elem.text = "ST_OMS_909908"
            pc_version_elem = ET.Element("Pc_version")
            pc_version_elem.text = "8031.25.65"
            oms_elem.append(build_path_elem)
            oms_elem.append(pc_version_elem)
            omni_elem = ET.Element("OMNI")
            build_path_omni_elem = ET.Element("Build_path")
            build_path_omni_elem.text = "ST_OMNI_798798789789"

            omni_elem.append(build_path_omni_elem)

            build_elem.append(oms_elem)
            build_elem.append(omni_elem)

            elem.append(build_elem)

            # Write to file
            tree.write("Build_new.xml") # After adding the new element
