DBMS_XSLPROCESSOR

Question

I have the following XML which I want to extract each value for the following:
*<TN>VALUE1</TN>*
*<TN2>VALUE2</TN2>*
*<TN>ANOTHER VALUE 1</TN>*
*<TN2>SECOND VALUE 2</TN2>*
and the following values:
*<DetailLine1>Detail line 1 value</DetailLine1>*
*<DetailLine2>detail line 2 value</DetailLine2>*
*<DetailLine1>Another value for detail line 1</DetailLine1>*
*<DetailLine2>second value for detail line 2 </DetailLine2>*
The XML I get is the following and I am using the code below but I get nothing as result - lenght is zero as result of DBMS_XMLDOM.GETLENGTH(v_nl));
Would you please help me, I am new in this and I have spent a lot in research and this has not worked.
p_xmltext varchar2(4000);
v_parser                DBMS_XMLPARSER.Parser;
v_xmldoc                DBMS_XMLDOM.DOMDocument;
v_nl                          DBMS_XMLDOM.DOMNodeList;
v_n                          DBMS_XMLDOM.DOMNode;
begin
p_xmltext:= '
<?xml version="1.0" encoding="utf-8" ?>
- <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">

<DetailLine2>detail line 2 value</DetailLine2>
</DETAIL>
</Items>

<DetailLine2>second value for detail line 2 </DetailLine2>
</DETAIL>
</Items>
</Items>
</ORD>
</SDResult>
</SDResp>
</soap:Body>
</soap:Envelope>';
v_parser := DBMS_XMLPARSER.newParser;
DBMS_XMLPARSER.parseBuffer(v_parser, p_XMLText);
v_xmldoc := DBMS_XMLPARSER.getDocument(v_parser);
-- Free resources associated with the Parser now it is no longer needed.
DBMS_XMLPARSER.freeParser(v_parser);
v_nl := DBMS_XSLPROCESSOR.selectNodes(DBMS_XMLDOM.makeNode(v_xmldoc),'//Items);
dbms_output.put_line('Number of records is '||DBMS_XMLDOM.GETLENGTH(v_nl));

Answer 1

The sample XML you provided in your first post does not have any nodes with the names in the XPaths you listed so I'm not surprised it didn't work.
Here is a starter version that works for you based off your first post. I got rid of using // because that is a slight performance hit and I try to avoid it when possible.
declare
   indoc VARCHAR2(2000);
   indomdoc dbms_xmldom.domdocument;
   l_nl dbms_xmldom.DOMNodeList;
   lv_value VARCHAR2(30);
   l_n dbms_xmldom.DOMNode;
   l_xmltype XMLTYPE;
   l_body    XMLTYPE;
   l_index PLS_INTEGER;
begin
  -- Test statements here
  l_xmltype := XMLTYPE('<?xml version="1.0" encoding="utf-8" ?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<soap:Body>
<SDResp xmlns="http://www.Aplace.com/processserver">
<SDResult>
<IDT>
<string>111</string>
<string>222</string>
</IDT>
<ORD>
<ONumber>3105</ONumber>
<ACC>ABC</ACC>
<Items>
<Items>
<TN>VALUE1</TN>
<TN2>VALUE2</TN2>
<DETAIL>
<DetailLine1>Detail line 1 value</DetailLine1>
<DetailLine2>detail line 2 value</DetailLine2>
</DETAIL>
</Items>
<Items>
<TN>ANOTHER VALUE 1</TN>
<TN2>SECOND VALUE 2</TN2>
<DETAIL>
<DetailLine1>Another value for detail line 1</DetailLine1>
<DetailLine2>second value for detail line 2 </DetailLine2>
</DETAIL>
</Items>
</Items>
</ORD>
</SDResult>
</SDResp>
</soap:Body>
</soap:Envelope>');
   l_body := l_xmltype.extract('/soap:Envelope/soap:Body/*','xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"');
   -- Change can * to the node name if always know it,  If include it, need to include namespace as well.
   l_index := 1;
   WHILE l_body.Existsnode('/SDResp/SDResult/ORD/Items/Items[' || To_Char(l_index) || ']','xmlns="http://www.Aplace.com/processserver"') > 0
   LOOP
      lv_value := l_body.extract('/SDResp/SDResult/ORD/Items/Items[' || To_Char(l_index) || ']/TN/text()','xmlns="http://www.Aplace.com/processserver"').getStringVal();
      dbms_output.put_line('Emp Name : '||lv_value);
      l_index := l_index + 1;
   END LOOP;
end;I know you will need to do more, but that covers the basics for everything you should need, such as getting TN2 and looping through all the DetailLine? records within each Items
Look in the FAQ in the upper right for how to use the { code } tag (no spaces) to retain formatting as shown above.
