public class LoadStep
extends ProcessStep

This processing step is used to load an input XML file.

Note that this processing step never parses the DTD (http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd, http://www.oasis-open.org/docbook/xml/4.5/docbookx.dtd, etc) possibly found at the beginning of the input XML file.

Method Detail

process

public void process(Object[] state,
                    Map<String,String> parameters,
                    int[] stepCounter,
                    ProgressMonitor monitor)
             throws Exception

Execute this processing step.

state[0] contains:

• Before this method is executed: input XML file.
• After this method is executed: loaded XML document.

Specified by:

process in class ProcessStep

Parameters:

state - contains the current state of processing: a Document or a File.

This object is used as the input of this step and thus, is processed by this step.

After its execution, this method generally updates the state array with a new Document or File to pass the result/output of this step to the next step.

parameters - all the parameters passed to the Processor owning and thus executing this process step.

Parameters which are relevant to this processing step are prefixed with "ProcessStep.stepName.".

stepCounter - contains the rank of previously executed processing step. Must be incremented by this method.

monitor - used to monitor the progress of the processing steps

Invoking convenience method ProcessStep.progress(java.lang.String, int[], com.xmlmind.util.ProgressMonitor) suffices to make good use of both monitor and stepCounter.

Throws:

Exception - if for any reason, this method fails
