public abstract int replacing(ReplacingArgs args)
                           throws java.lang.Exception

A user defined method that is called during a replace operation for each match found just before a replace is made.

Returns:

A ReplaceAction value. A ReplaceAction value that specifies the action to be taken for the current match.

Example:

Replaces text specified with regular expression with HTML.

public void replaceWithInsertHtml() throws Exception
{
    // Open the document.
    Document doc = new Document(getMyDir() + "Range.ReplaceWithInsertHtml.doc");

    doc.getRange().replace(Pattern.compile("<CustomerName>"), new ReplaceWithHtmlEvaluator(), false);

    // Save the modified document.
    doc.save(getMyDir() + "Range.ReplaceWithInsertHtml Out.doc");

}

private class ReplaceWithHtmlEvaluator implements IReplacingCallback

    /**
     * NOTE: This is a simplistic method that will only work well when the match
     * starts at the beginning of a run.

Example:

Shows how to insert content of one document into another during a customized find and replace operation.
