python - Parse XML using lxml -


i have following xml need parse. of issue seems can't stingio work. looks can't load module; guess i'm not sure how show it's loaded properly? below xml, returned response http request:

<response method="switchvox.currentcalls.getlist">     <result>             <current_calls total_items="3">                             <current_call id="sip/6525-b59313c8" from_caller_id_name="user1" from_caller_id_number="user1_ext" to_caller_id_name="callee1" to_caller_id_number="callee1_num"  start_time="2011-06-30 15:44:17" duration="346" state="talking" provider="internal" format="g722-&gt;g722" />                             <current_call id="sip/4476-b595a0a0" from_caller_id_name="user2" from_caller_id_number="user1_ext" to_caller_id_name="callee2" to_caller_id_number="callee2_num"  start_time="2011-06-30 15:48:44" duration="79" state="talking" provider="vcg_b" format="g722-&gt;ulaw" />                             <current_call id="sip/4483-0aa41320" from_caller_id_name="user3" from_caller_id_number="user1_ext" to_caller_id_name="callee3" to_caller_id_number="callee3_num"  start_time="2011-06-30 15:47:54" duration="129" state="talking" provider="vcg_b" format="g722-&gt;ulaw" />             </current_calls>     </result>

the goal each attribute, per 'current_call' it's own variable, can dump them table elsewhere. unless can store them in memory or something? want keep them 1 more cycle, or until not see particular 'id' anymore (and can assume call has ended).

can like

for root.result.current_calls.current_call in root.result.current_calls:         id = root.result.current_calls.current_call.get("id")         .         .         <send variables database within for.. loop>

i'm sure theres better way this! 

from lxml import etree  xml_string = """ <response method="switchvox.currentcalls.getlist">     <result>             <current_calls total_items="3">                             <current_call id="sip/6525-b59313c8" from_caller_id_name="user1" from_caller_id_number="user1_ext" to_caller_id_name="callee1" to_caller_id_number="callee1_num"  start_time="2011-06-30 15:44:17" duration="346" state="talking" provider="internal" format="g722-&gt;g722" />                             <current_call id="sip/4476-b595a0a0" from_caller_id_name="user2" from_caller_id_number="user1_ext" to_caller_id_name="callee2" to_caller_id_number="callee2_num"  start_time="2011-06-30 15:48:44" duration="79" state="talking" provider="vcg_b" format="g722-&gt;ulaw" />                             <current_call id="sip/4483-0aa41320" from_caller_id_name="user3" from_caller_id_number="user1_ext" to_caller_id_name="callee3" to_caller_id_number="callee3_num"  start_time="2011-06-30 15:47:54" duration="129" state="talking" provider="vcg_b" format="g722-&gt;ulaw" />             </current_calls>     </result> </response> """  tree = etree.fromstring(xml_string)  call in tree.xpath('.//current_call'):     print call.attrib

gives:
