Adding a XML element using shell or Python

we have a requirement to insert XML element in multiple locations

i have to insert one more element

<wtc-import>
      <name>WTCImportedService-0-rap01</name>
      <resource-name>XXXX01F</resource-name>
      <local-access-point>lap01</local-access-point>
      <remote-access-point-list>rap01</remote-access-point-list>
      <remote-name>XXXX01F</remote-name>
    </wtc-import>

in the ---INSERT WTC IMPORT SERVICE---- mentioned location in the below file

basically before the end of each < /wtc-server> tag

  <wtc-server>
    <name>WTC-server-117-02</name>
    <target>cwea_117_02</target>
    <wtc-local-tux-dom>
      <name>lap01</name>
      <access-point>lap01</access-point>
      <access-point-id>wl.prodcwe117.02</access-point-id>
      <block-time>600</block-time>
      <nw-addr>//localhost:7125</nw-addr>
    </wtc-local-tux-dom>
    <wtc-remote-tux-dom>
      <name>rap01</name>
      <access-point>rap01</access-point>
      <access-point-id>tx.hello101</access-point-id>
      <local-access-point>lap01</local-access-point>
      <nw-addr>//hostanme:71105</nw-addr>
      <federation-url></federation-url>
      <federation-name></federation-name>
    </wtc-remote-tux-dom>
    <wtc-import>
      <name>WTCImportedService-0-rap01</name>
      <resource-name>XXXX01F</resource-name>
      <local-access-point>lap01</local-access-point>
      <remote-access-point-list>rap01</remote-access-point-list>
      <remote-name>XXXX01F</remote-name>
    </wtc-import>

Please help

Doing this in shell with XMLStarlet would look like:

xmlstarlet ed \
  --subnode '//wtc-server' -t elem -n wtc-import \
  --subnode '//wtc-server/wtc-import[last()]' -t elem -n name -v WTCImportedService-0-rap01 \
  --subnode '//wtc-server/wtc-import[last()]' -t elem -n resource-name -v XXXX01F \
  --subnode '//wtc-server/wtc-import[last()]' -t elem -n local-access-point -v lap01 \
  --subnode '//wtc-server/wtc-import[last()]' -t elem -n remote-access-point-list -v rap01 \
  --subnode '//wtc-server/wtc-import[last()]' -t elem -n remote-name -v XXXX01F \
  <in.xml >out.xml

(code tested without any xmlns definitions, since the original version of the question didn't contain any).
