All known Subclasses: org.apache.cocoon.components.language.markup.xsp.XSPExpressionFilter,
| XSPExpressionParser | | public class XSPExpressionParser (Code) | | Parse XSP expressions. Expressions are embedded in attribute="value" and text elements and are
expanded by the
org.apache.cocoon.components.language.markup.xsp.XSPMarkupLanguage.PreProcessFilter PreProcessFilter and have the form {#expression}. To prevent interpolation, use {##quote}, which results in the
text {#quote}.
An exception is thrown if the closing brace is missing.
The parser has a rudimentary understanding of expressions concerning
nested braces and braces inside quoted strings and character constants.
All valid Java, Javascript, and Python expressions can be used.
Example: <h1>Hello {#user.getName()}</h1> <img or
src="image_{#image.getId()}"/>
