Update AEM Tags name with lower case

[varuns46785756]

Hi,

I am using AEM 6.1 and I have created more then 200 tags with upper case letter in my application ( example:Tag Title: Buy a car, Tag name: Buy-a-car).

I need to follow the correct naming convention and convert the tag name with lower case like :Tag name should be " buy-a-car". Is there any way to convert all the tag name with lower case without deleting or recreating new one or can i run any query to update the name.

Please suggest.

Regards,

Sunil

You can do the following :

- create a servlet  and using QueryManager or any search API to find all tags like (1)

- Iterate over the result set and use java string api to make the items in the resultset to lowercase

- Persist the items back to same location

(1) - select * from [cq:Tag] where isdescendantnode([/etc/tags])

You can quickly write a small fiddle script using ACS tools without adding this code your source repo

Here is the fiddle script to convert all tag names jcr:title to lowercase. Modify according to your requirement

package apps.acs_002dtools.components.aemfiddle.fiddle;

import com.day.cq.search.*;

import com.day.cq.wcm.api.*;

import com.day.cq.dam.api.*;

import org.apache.sling.api.*;

import org.apache.sling.api.resource.*;

import org.apache.sling.api.servlets.*;

import java.io.IOException;

import javax.jcr.*;

import java.util.*;

public class fiddle extends SlingAllMethodsServlet {

    @Override

    protected void doGet(SlingHttpServletRequest request, SlingHttpServletResponse response) throws IOException {

        // Code here

        //response.getWriter().println("Hello from " + request.getResource().getPath());

        Resource resource = request.getResourceResolver().getResource("/content/cq:tags/we-retail");

Session session =  request.getResourceResolver().adaptTo(Session.class);

        if (resource != null) {

            // Writing HTML in servlets is usually inadvisable, and is better suited to be provided via a JSP/Sightly template

            // This is just an example.

           if (resource != null) {

Iterator<Resource> linkResources = resource.listChildren();

while (linkResources.hasNext()) {

Resource childResource = linkResources.next();

try{

Node childNode = childResource.adaptTo(Node.class);

String tagName = childNode.getProperty("jcr:title").getString();

childNode.setProperty("jcr:title",tagName.toLowerCase());

session.save();

response.getWriter().write(""+childNode.getProperty("jcr:title").getString());

}catch(RepositoryException re){}

}

}

            // By Default the 200 HTTP Response status code is used; below explicitly sets it.                   

            response.setStatus(SlingHttpServletResponse.SC_OK);

        } else {

            // Set HTTP Response Status code appropriately

            response.setStatus(SlingHttpServletResponse.SC_INTERNAL_SERVER_ERROR);

            response.getWriter().write("ERROR");

        }

    }

}
