![]() ![]() Relevant information Oracle Database 11g Enterprise Edition Release 11.1.0.7. Should I change some settings? (Relevant settings shown below).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. XMLELEMENT("Hiredate", e.I'm trying to decode html containing html entities. WHERE d.department_id = e.department_id) as "Dept_name")), (SELECT d.department_name FROM departments d ![]() XMLELEMENT("Dept", XMLATTRIBUTES(e.department_id, SELECT XMLELEMENT("Emp", XMLATTRIBUTES(e.employee_id, e.last_name), As a result, the XML returned uses the column name last_name as the default.įinally, the next example uses a subquery within the XML_attributes_clause to retrieve information from another table into the attributes of an element: Notice that the AS identifier clause was not specified for the last_name column. XMLELEMENT("Salary", e.salary)) AS "Emp Element" XMLATTRIBUTES(e.employee_id AS "ID", e.last_name), The following similar example uses the XMLElement function with the XML_attributes_clause to create nested XML elements with attribute values for the top-level element: XMLELEMENT("Hiredate", e.hire_date)) as "Result"įROM employees e WHERE employee_id > 200 SELECT XMLELEMENT("Emp", XMLELEMENT("Name", The following example produces an Emp element for a series of employees, with nested elements that provide the employee's name and hire date: If you specify an alias for value_expr using the AS clause, then the c_alias or the evaluated value expression ( EVALNAME value_expr) can be up to 4000 characters if the initialization parameter MAX_STRING_SIZE = STANDARD, and 32767 characters if MAX_STRING_SIZE = EXTENDED. The type of value_expr cannot be an object type or collection. In the XML_attributes_clause, if the value_expr is null, then no attribute is created for that value expression. The objects that make up the element content follow the XMLATTRIBUTES keyword. It can be up to 4000 characters if the initialization parameter MAX_STRING_SIZE = STANDARD, and 32767 characters if MAX_STRING_SIZE = EXTENDED. I've tried nvert and utli18n.unescapereference but the results are less than satisfactory. The identifier does not have to be a column name or column reference. How to convert html entities in Oracle Ask Question Asked 8 years, 6 months ago Modified 8 years, 6 months ago Viewed 7k times 2 I'm trying to decode html containing html entities. In the latter case, the value expression is evaluated and the result, which must be a string literal, is used as the identifier. You can do this by specifying identifier, which is a string literal, or by specifying EVALNAME value_expr. You must specify a value for Oracle Database to use an the enclosing tag. The XMLElement function is typically nested to produce an XML document with a nested structure, as in the example in the following section.įor an explanation of the ENTITYESCAPING and NONENTITYESCAPING keywords, refer to Oracle XML DB Developer's Guide. XMLElement is similar to SYS_XMLGen except that XMLElement can include attributes in the XML returned, but it does not accept formatting using the XMLFormat object. XMLElement takes an element name for identifier or evaluates an element name for EVALNAME value_expr, an optional collection of attributes for the element, and arguments that make up the content of the element. ![]()
