Method Summary | |
void |
destroy()
Cleanup; called when applet is terminated and unloaded. |
String |
escapeString(String s)
Given a String containing markup, escape the markup so it can be displayed in the browser. |
void |
freeCache()
The processor keeps a cache of the source and style trees, so call this method if they have changed or you want to do garbage collection. |

String |
getTreeAsText(String treeURL)
Get an XML document (or stylesheet) |
void |
init()
Standard applet initialization. |
void |
paint(Graphics g)
Do not call; this applet contains no UI or visual components. |
void |
setDocumentURL(String urlString)
Set the URL to the XML document that will be transformed with the XSL stylesheet. |
void |
setStyleSheetAttribute(String nameOfIDAttrOfElemToModify,
String elemId,
String attrName,
String value)
Set an attribute in the stylesheet, which gives the ability to have some dynamic selection control. |
