Problem about "addChild" with libxml2 for Python

[Kun JIN <kun jin univ-bpclermont fr>]

Hello, everyone

I don't know am i right place here, i found this mailing list at libxml2 website.

Last day, i used libxml2 module for Python too analyze my XML file, but i got a strange result, one other part has been added in the result, like below:


_______________The script:

    spe_nodes = corp.act_type()
    dooooc = libxml2.parseDoc("<acts/>")
    mmerde = dooooc.getRootElement()
    for n in spe_nodes[-1:]: # i tested one node
        print "__________________node context:\n",n
        mmerde.addChild(n)
        print "__________________after addChild:"
        print mmerde
    outfile = open("aaaaact_chat","w")
    dooooc.saveTo(outfile)
    outfile.close()


___________________Result with print:

__________________node context:
<mcesid:act id="Simu-Chat_Test_Room4_S03_00011" tool_ref="Simu-Chat_Test_Room4">

                            <mcesid:act_type>
