How to Read and parse XML in Oracle using EXTRACTVALUE and XMLTABLE.Should I use another function? (These were recommended somewhere on the Internet).How can I have all entities properly decoded? However, is this Oracle itself doing this, or the client (I tried in both SQL+ and Toad)? When I plug utl_i18n.unescape_reference into the query used by the Java program, it works for entities like ± (±), but again, not for the Chinese characters. I realise that in the second row, the inverted question marks seem to indicate that the entities were converted, but can't be displayed properly. These aren't decoded properly, as can be seen in the example above. I have no easy access to the Java code, but I do have control over the query used by the program.Īn example of Chinese characters that I use for testing is 激光, which Google Translate tells me means 'laser' and which I receive encoded as 激 光. My actual problem involves Chinese characters, processed by a Java program to create PDF reports. The results I get are: METHOD HEARTS AMP_ENT AMP_DEC AMP_HEX CHINESE_LASERĭbms_nvert ♥ & & & 激 光 I've tried dbms_nvert and utl_i18n.unescape_reference but the results are less than satisfactory. You can then use XMLTable to extract the attributes as traditional rows and columns.I'm trying to decode html containing html entities. Nest each set of elements in their own GROUP (or whatever) element. This makes it tricky to identify the corresponding BUS_UNIT_ACRN for a given GROUP_ID. TNS for Solaris: Version 9.2.0.5.0 - Productionīoth the GROUP_ID elements have the same parent. Oracle9i Enterprise Edition Release 9.2.0.5.0 - Production LPX-00241: entity reference is not well formed ORA-19202: Error occurred in XML processing SQL> insert into t values ('test &test') What we will see in this article XML Parsers for processing data How to process XML data with Oracle PL/SQL with multiple scenarios. The article will give information about how to do the xml file processing with multiple scenarios. SQL> select xmltype(t.cl).extract('/root/text()').getStringVal() Oracle has introduced a separate in built package for processing the xml data named XMLDB package. SQL> insert into t values ('test & test') If you omit the initial slash, then the context of the relative path. You can specify an absolute XPathstring with an initial slash or a relative XPathstring by omitting the initial slash. It applies a VARCHAR2 XPath string and returns an XMLType instance containing an XML fragment. XMLTYPE(E.X).EXTRACT('/REQUEST_DETAIL/GROUP_TYPE/TEXT()').GETSTRINGVAL() EXTRACT (XML) is similar to the EXISTSNODE function. ORA-22806: not an object or select xmltype(e.x).extract('/REQUEST_DETAIL/GROUP_TYPE/text()').getStringVal() Select e.x.extract('/REQUEST_DETAIL/GROUP_TYPE/text()').getStringVal() Here is a temporary solution - long term, use the right type for the create table t ( x clob ) ġ row select e.x.extract('/REQUEST_DETAIL/GROUP_TYPE/text()').getStringVal() You'll spend the rest of your life converting - and if the data in the clob isn't actually XML (well formed enough), you won't find out until you need it (just like when that string that should be a number contains 'hello world') FROM testxml t, XMLTable ( '//record' passing t. Direct CLOB projection is supported starting with 11.2.0.2, using XMLTable or XMLCast/XQuery functions (extractvalue, extract, xmlsequence are deprecated now) : SELECT x. Well, you know - this is alot like storing a DATE in a number, a number in a string. Answer: You use the extractvalue procedure for extracting XML from a CLOB in Oracle SQL select statements. Same on xmltype column but they do not work on a clob. I have seen various examples of doing the Please show me how to extract the value out of an xml tag on a clob using a sql query. However the same code works in a PL/SQL block where i convert the request_detail (clob) to sys.xmltype before using the extract Select e.request_detail.extract('/REQUEST_DETAIL/GROUP_TYPE/text()').getStringVal() Sql > select e.request_detail.extract('/REQUEST_DETAIL/GROUP_TYPE/text()').getStringVal() I tried the following but am getting an error I need a query to extract the value in the Group_type tag.
