Library: XSLT support (OMXSLT) Import: omxslt.xmd

Return type: String Returns: The result of applying the stylesheet to the xml-input argument.

Declaration

export external string source function reader
              with value     stylesheet stylesheet
        parameters read-only stream     parameters optional
              from value     source     xml-input

Argument definitions

stylesheet

is the XSLT stylesheet that will be applied to the input data,

parameters

is a shelf of parameters required by the stylesheet, and

xml-input

is a well-formed XML instance to which the stylesheet will be applied.

Use reader to apply an XSLT stylesheet to a well-formed XML instance. The result of the transformation is emitted to #current-output, where it can be captured in a stream, or used to feed OmniMark's XML parser or its pattern-matching engine.

Usage Note

To use reader, you must import omxsltinto your program, using a statement like this:

  import "omxslt.xmd" prefixed by xslt.

Example

An XSLT stylesheet stored in a file stylesheet1.xsl can be applied to a well-formed XML instance stored in file |input1.xml using the following program.

          import "omxslt.xmd" prefixed by xslt.
          
          process
             do xml-parse scan xslt.reader with xslt.compile file "stylesheet1.xsl"
                                                  from file "input1.xml"
                suppress
             done
  
          element #implied
             suppress
        

If the stylesheet is being applied only once, there is no need to declare a shelf of type stylesheet: OmniMark can convert a stream representation of the stylesheet into the appropriate format. The above example can then be modified to read

          do xml-parse scan xslt.reader with file "stylesheet1.xsl"
                                               from file "input1.xml"
             suppress
          done
