Get html output from a jcr node in CQ5

Question

I wanted to know if there is a way to get the rendered HTML output of a Page node in CQ5 without hitting the actual url. I have the Page node and I want to get the rendered HTML output of that Page node programmatically in java and store it in a string without hitting the page URL.

Any help is appreciated, thanks in advance!

Node itself it's just a data. Sling framework responsible for rendering this data. It use a bunch of rules to determine how this data should be rendered.Sling Script Resolution Cheet Sheet As Sling is web framework it renders data via http requests.

To emulate this request in CQ/AEM I suggest to use com.day.cq.contentsync.handler.util.RequestResponseFactory service

import org.apache.sling.engine.SlingRequestProcessor;
import com.day.cq.contentsync.handler.util.RequestResponseFactory;

@Reference
private RequestResponseFactory requestResponseFactory;

@Reference
private SlingRequestProcessor requestProcessor;

public String doStuff(){
    HttpServletRequest request = requestResponseFactory.createRequest("GET", "/path/to/your/node.html");
    request.setAttribute(WCMMode.REQUEST_ATTRIBUTE_NAME, WCMMode.DISABLED);

    ByteArrayOutputStream out = new ByteArrayOutputStream();
    HttpServletResponse response = requestResponseFactory.createResponse(out);

    requestProcessor.processRequest(request, response, resourceResolver);        
    return out.toString(response.getCharacterEncoding());
}

Hope it helps.

You can access node by providing a correct view. As you need rendered html view, use .html with your node to get rendered html. So your node path will be

/content/path/to/page/jcr:content/par/node_name.html

Now to read html programmatically, you can make an http request to above path from your path, and save response as string.
