public class SQLQuery extends ExtensionInstruction
An sql:query element in the stylesheet. For example:<sql:query column="{$column}" table="{$table}" where="{$where}" xsl:extension-element-prefixes="sql"/ >
(result with HTML-table-output)
<sql:query column="{$column}" table="{$table}" where="{$where}" row-tag="TR" column-tag="TD" separatorType="tag" xsl:extension-element-prefixes="sql"/ >

Method Detail

prepareAttributes
public void prepareAttributes() throws XPathException
Description copied from class:StyleElement
Set the attribute list for the element. This is called to process the attributes (note the distinction from processAttributes in the superclass). Must be supplied in a subclass- Specified by:
prepareAttributes
in classStyleElement
- Throws:
XPathException
-
validate
public void validate() throws XPathException
Description copied from class:StyleElement
Check that the stylesheet element is valid. This is called once for each element, after the entire tree has been built. As well as validation, it can perform first-time initialisation. The default implementation does nothing; it is normally overriden in subclasses.- Overrides:
validate
in classExtensionInstruction
- Throws:
XPathException
-
compile
public Expression compile(Executable exec) throws XPathException
Description copied from class:StyleElement
Compile the instruction on the stylesheet tree into an executable instruction for use at run-time.- Specified by:
compile
in classStyleElement
- Returns:
- either a ComputedExpression, or null. The value null is returned when compiling an instruction that returns a no-op, or when compiling a top-level object such as an xsl:template that compiles into something other than an instruction.
- Throws:
XPathException
