sql - Issue With Pulling Remote XML Data into Oracle Database -


in oracle database, reading xml restful web service looks this:

<ns1:parent xmlns:ns1="http://www.example.com/xml"    xmlns:xsi="http://www.w3.org/2001/xmlschema-instance"   xs1:schemalocation= "http://www.example.com/xml http://www.w3.org/2001/xmlschema-instance">     <ns1:child>       <ns1:options></ns1:options>       <ns1:variables></ns1:variables>       <ns1:values>         <ns1:value qualifiers="x" date="sometime">value1</ns1:value>         <ns1:value qualifiers="x" date="someothertime">value2</ns1:value>         ...         <ns1:value qualifiers="x" date="some100thtime">value100</ns1:value>       </ns1:values>     </ns1:child>

i trying take data , extract database using code below. however, when creates 1 record sysdate field , other 2 values blank. attempted xmltable, had same result. i'm thinking there's issue namespace, can't find proper syntax , other combinations i've tried don't return rows @ all.

we pull data another, identical data source not use namespaces, , code works fine (without of namespaces, of course). getting syntax of namespaces wrong somewhere?

declare myxmltype xmltype := xmltype(we use function pull in xml file here); begin /*outputting xmltype here shows data in it*/ insert output_table    select      extractvalue(value(p), '/values/ns1:value',          'xmlns:ns1="http://www.example.com/xml"') myvalue,     extractvalue(value(p), '//values/ns1:value/@ns1:date',          'xmlns:ns1="http://www.example.com/xml"') mytime,     sysdate read_date        table(xmlsequence(extract(myxmltype, '/ns1:parent/ns1:child/ns1:values',          'xmlns:ns1="http://www.example.com/xml"')))p;   commit;  end;

you can use xmltable thought, need supply xmlnamespaces clause too. using bind variable called string holds xml text (with couple of corrections):

var string varchar2(200);  begin   :string := '<ns1:parent xmlns:ns1="http://www.example.com/xml"    xmlns:xsi="http://www.w3.org/2001/xmlschema-instance"   ns1:schemalocation= "http://www.example.com/xml http://www.w3.org/2001/xmlschema-instance">     <ns1:child>       <ns1:values>         <ns1:value qualifiers="x" date="sometime">value1</ns1:value>         <ns1:value qualifiers="x" date="someothertime">value2</ns1:value>       </ns1:values>     </ns1:child>   </ns1:parent>'; end; /  select myvalue, mytime, sysdate read_date xmltable(xmlnamespaces('http://www.example.com/xml' "ns1"),   '/ns1:parent/ns1:child/ns1:values/ns1:value'   passing xmltype(:string)   columns myvalue varchar2(20) path '.',     mytime varchar2(20) path '@date' );  myvalue              mytime               read_date -------------------- -------------------- ---------- value1               sometime             2016-07-25 value2               someothertime        2016-07-25

you can same thing insert ... select using myxmltype variable in passing clause, instead of xmltype(:string).

extractvalue deprecated anyway, , can return 1 node ora-19025 if had xpath right.
