Question

Dear experts:
does abap supports  xpath  to sellect particular  nodes  according some node value or condition, i know other  programe language  supports the function selectNode(xpath expression)  , does abap or have the api to support it?
and i know there is a class support  the xpath but it's not work., the class this:cl_xslt_processor
to clarify my point. i take a ex.
the xml doc is follow:
<?xml version="1.0" encoding="utf-8" ?>
- <n0:MT_CRM_Req xmlns:n0="http://gome.com/CRM/CRM/Outbound" xmlns:prx="urn:sap.com:proxy:DC0:/1SAI/TAS05C79364B9D0DC5F6738:701:2010/02/19">
<company name="hp">
<dep name="gds">
<empolyeeid>123</empolyeeid>
</dep>
<dep name="its">
<empolyeeid>148</empolyeeid>
</dep>
</company>
<company name="foxconn">
<dep name="fih">
<empolyeeid>569</empolyeeid>
</dep>
</company>
  </n0:MT_CRM_Req>
i  want to  select the employee 's company name who empolyee id is 123
i use the method  ,and the code is :
l_xslt->set_expression(
expression = '/n0:MT_CRM_Req/n0:company[n0:dep/n0:empolyeeid=123]'
nsdeclarations = 'n0 http://gome.com/CRM/CRM/Outbound'
l_xslt->run('').
nodes = l_xslt->get_nodes( ).
LEN = nodes->GET_LENGTH( ) .
WRITE LEN.
but no nodes return.
is anybody knows what's wrong with it? or there is some other api to manipulate the xml dom.

Hello Kevin ,
i think you can get those details , have a look at program BCCIIXMLT1, i think this program will give you some idea to handle * manage xml docs.
along with that program ...you need to put filter
*---creating filers.
  filter   = document->create_filter_name( name = 'Company' ).
  iterator = document->create_iterator_filtered( filter ).
  main_node =  document.
*---processing document.
  perform print_node using main_node p_flag.
let me know if you need anymore help.
