Hi all, 

I need to show the node hierarchy (tree view) based on the node path provided.

For example if path is like : /content/samples/assets/images

      I need to List all the child nodes , files , resource types, assets that are under the given node path. and populate it in html page using tree view structure, I mean to say same structure the node has in CRXDE Lite.

I hope you understand my question.

Please help me fetch all the nodes , childs, files, resources, cr content under the specified node to build same tree view/hierarchical structure with expand (+) buttons to access sub nodes/child(s) from the html page by user

 

any suggestion is greatly appreciated.+

Thanks

To query the AEM JCR (and child nodes) - you should use the JCR API (JCR-SQL).

See this article for a good discussion on using JCR SQL:

http://docs.jboss.org/exojcr/1.12.13-GA/developer/en-US/html/ch-jcr-query-usecases.html

For your use case -- i would consider using JCR SQL. You can build algorithms to query child nodes and thier child nodes, etc. Then place the results in a collection to track them. 

There are some examples here of querying children nodes:

http://docs.jboss.org/exojcr/1.12.13-GA/developer/en-US/html/ch-jcr-query-usecases.html#d0e3517

If you are going to build JCR API logic from within an OSGi bundle -- you will want to read this community article. It talks about using the JCR API to query AEM data from within a bundle:

Hi, 

I tried to pull data for a path like : /content/samples/assets/images 

using 

string url = http://host ip:4502//content/samples/assets/images.xml

var webrequest = new httpwebreqeust(url);

//pass credentials

httpwebresponse response = webrequest.getresponse()

string resultxml = response.getresponsestream().readtoend();

            xmldocument xdoc = new xmldocument();

xdoc.loadxml( resultxml);

//loop through xdoc and build tree view.   

 

but,  I feel this is not the correct way , looking for some other ways to achieve the same, 

I am looking for query builder to query assets and fetch xml

 

do u have any idea/suggestions?
