XML from CLOB

Question

Hello,
We have encountered a problem:
We are using Windows-1250 codepage (EE8MSWIN1250) with Oracle8i 8.1.7.0. When we use correct string with special characters (from Slovak language) in CLOB, after loading it to the XML parser and retrieving it back from XML parser, we are getting '?' instead of special characters.
The sample showing this problem is following:
DECLARE
xp xmlparser.parser;
xmldoc xmldom.domdocument;
xmlnode xmldom.domnode;
v_params CLOB;
v_in_temp CLOB;
v_buffer VARCHAR(255);
BEGIN
v_buffer := '<?xml version="1.0" encoding="ISO-8859-2"?><unicode name="a&#353;}h&#382;&#353;h&#382;h&#382;}imTotoUzIdeCitat+5ac;l}amin)CN."/>';
v_buffer := CONVERT(v_buffer,'EE8ISO8859P2','EE8MSWIN1250'); --EE8ISO8859P2
xp := xmlparser.newparser;
xmlparser.setValidationMode(xp, FALSE);
xmlparser.setPreserveWhiteSpace(xp, TRUE);
dbms_output.put_line('Input buffer:');
dbms_output.put_line(v_buffer);
dbms_lob.createtemporary(v_in_temp,false);
dbms_lob.write(v_in_temp,LENGTH(v_buffer),1,v_buffer);
dbms_output.put_line('Input CLOB:');
tools.put_clob(v_in_temp);
xmlparser.parseclob(xp,v_in_temp);
-- xmlparser.parsebuffer(xp,v_buffer);
xmldoc := xmlparser.getdocument(xp);
xmlnode := xmldom.makenode(xmldom.getdocumentelement(xmldoc));
--nacitame name a uname procesu
DECLARE o_buffer VARCHAR2(255);
o_clob CLOB;
BEGIN
xmldom.writetoBuffer(xmlnode,o_buffer);
dbms_output.put_line('Output Buffer:');
dbms_output.put_line(o_buffer);
dbms_lob.createtemporary(o_clob,true);
xmldom.writetoClob(xmlnode,o_clob);
dbms_output.put_line('Output Clob:');
tools.put_clob(o_clob);
--?? Why this output clob is not the same as output buffer??
dbms_lob.freetemporary(o_clob);
END;
END;
Does anybody know what we are doing wrong?

Answer 1

OK, so that gives me one column with just the <clob>, but I want the data to be parsed back out into it's columns and rows..
So the clob for this column might hold this XML:
<?xml version="1.0"?>
<ROWSET>
<ROW>
<SORCONT_PIDM>99955</SORCONT_PIDM>
<SORCONT_CTYP_CODE>TAP</SORCONT_CTYP_CODE>
</ROW>
</ROWSET>
What I want a query of this one column to produce:
SORCONT_PIDM SORCONT_CTYP_CODE
99955 TAP
