Examples with MCRErrorListener org.mycore.common.xsl.MCRErrorListener used on opensource projects

Example 1 with MCRErrorListener

use of org.mycore.common.xsl.MCRErrorListener in project mycore by MyCoRe-Org.

the class MCRXSLTransformer method transform.

@Override
public void transform(MCRContent source, OutputStream out, MCRParameterCollector parameter) throws IOException {
    MCRErrorListener el = null;
    try {
        LinkedList<TransformerHandler> transformHandlerList = getTransformHandlerList(parameter);
        XMLReader reader = getXMLReader(transformHandlerList);
        TransformerHandler lastTransformerHandler = transformHandlerList.getLast();
        el = (MCRErrorListener) lastTransformerHandler.getTransformer().getErrorListener();
        StreamResult result = new StreamResult(out);
        lastTransformerHandler.setResult(result);
        reader.parse(source.getInputSource());
    } catch (TransformerConfigurationException | SAXException | IllegalArgumentException | ParserConfigurationException e) {
        throw new IOException(e);
    } catch (RuntimeException e) {
        if (el != null && e.getCause() == null && el.getExceptionThrown() != null) {
            // typically if a RuntimeException has no cause, we can get the "real cause" from MCRErrorListener, yeah!!!
            throw new IOException(el.getExceptionThrown());
        }
        throw e;
    }
}

Example 2 with MCRErrorListener

use of org.mycore.common.xsl.MCRErrorListener in project mycore by MyCoRe-Org.

the class MCRXSLTransformer method getTransformHandlerList.
