SAP ABAP:阅读XML文档时忽略命名空间

Question

以下问题：我有一个XML文档，我将使用SAP ABAP阅读。看起来这样：

<n0: someName >
<n0: someOtherName >
   <n1: underName />
      <n16: underUnderStuff />
</n0: someName>
</n0: someOtherName>

因此，问题似乎是N0，N1等。我已将其删除以进行测试并起作用。在ABAP中使用Find_note时，程序只能读取第一行。搜索例如第二个是行不通的。有人知道如何忽略N0等吗？片段请。

您可以使用cl_xslt_processor在ABAP中使用XPATH功能来查找元素。

REPORT zmky_xml_localname.
DATA: lv_string     TYPE string,
      lv_xstring    TYPE xstring,
      lv_document   TYPE REF TO if_ixml_document,
      lo_processor  TYPE REF TO cl_xslt_processor,
      lo_nodes      TYPE REF TO if_ixml_node_collection,
      lo_node       TYPE REF TO if_ixml_node,
      lv_i          TYPE i.
CONCATENATE
  '<n0:someName xmlns:ns0="http://ns0">'
  '<n0:someOtherName>'
     '<n1:underName  xmlns:ns0="http://ns1"/>'

  '</n0:someName>'
  '</n0:someOtherName>'

lv_xstring = cl_proxy_service=>cstring2xstring( lv_string ).

CREATE OBJECT lo_processor.
lo_processor->set_source_node( node = lv_document ).
lo_processor->set_expression( expression = '//*[local-name()="underUnderStuff"]' ).
lo_processor->run( progname = space ).
lo_nodes = lo_processor->get_nodes( ).

lv_string = lo_node->get_value( ).
WRITE /: lv_string.
