### Field Summary

Fields
`static java.lang.String` `FILE_PROTOCOL_PREFIX` the file protocol prefix for systemid.

### Method Summary

All Methods Instance Methods Abstract Methods
`void` `addParam(java.lang.String name, java.lang.String expression)` Add a parameter to be set during the XSL transformation.
`void` `setStylesheet(java.io.File stylesheet)` set the stylesheet to use for the transformation.
`void` `transform(java.io.File infile, java.io.File outfile)` Perform the transformation of a file into another.

### Field Detail

#### FILE_PROTOCOL_PREFIX

    static final java.lang.String FILE_PROTOCOL_PREFIX

the file protocol prefix for systemid. This file protocol must be appended to an absolute path. Typically: `FILE_PROTOCOL_PREFIX + file.getAbsolutePath()` Note that on Windows, an extra '/' must be appended to the protocol prefix so that there is always 3 consecutive slashes.
