How to convert between various types of data:
Please help by adding best-practice sample code (and links to other pages with more detailed explanations) for various environments in Cocoon, such as plain Java objects, Flowscript, XSP, XSL, JXPath, etc. Also, please feel free to refactor, rename, or even rewrite this page as needed.
Unescaped String -> Escaped String
In Java code
import org.apache.commons.lang.StringEscapeUtils;
public String escape(String input) {
return StringEscapeUtils.escapeJava(input);
}
In Flowscript
function escapeString(unescaped_string) {
return Packages.org.apache.commons.lang.StringEscapeUtils.escapeJavaScript(unescaped_string);
}
The library commons-lang-2.0 is in the lib/core folder of cocoon distribution and contains a lot of other helpful functionality
Escaped String -> Unescaped String
In Java code
import org.apache.commons.lang.StringEscapeUtils;
public String escape(String input) {
return StringEscapeUtils.unescapeJava(input);
}
In Flowscript
function unescapeString(escaped_string) {
return Packages.org.apache.commons.lang.StringEscapeUtils.unescapeJavaScript(escaped_string);
}
Unescaped String -> DOM
import org.apache.excalibur.xml.dom.DOMParser;
import org.w3c.dom.Document;
import org.xml.sax.InputSource;
ServiceManager manager;
(obtained via Serviceable or something)
public Document stringToDOM(String input) throws Exception {
Document result = null;
DOMParser parser = null;
try {
parser = (DOMParser)manager.lookup(DOMParser.ROLE);
result = parser.parseDocument(new InputSource(new StringReader(input)));
} finally {
manager.release(parser);
}
return result;
}
Unescaped String -> DOM fragment
DOM -> Unescaped String
FlowScript:
function serializeNode(node) {
return Packages.org.apache.cocoon.xml.XMLUtils.serializeNodeToXML(node);
}
