Re: Any good resources for learning sql/xpath usage in Magnolia?

Thank you for the links,

I've tried some xpath queries and I have a question. According to various sources the following

Query query = MgnlContext.getQueryManager("website").createQuery("//todos/*", "xpath");
...

should return all the children of 'todos' nodes. When I iterate the result using this:

qls = result.getContent("mgnl:contentNode");
 
I receive the following result:

website:/hello-world/paragraphs/0/todos[mgnl:contentNode]
website:/hello-world/paragraphs/0/todos/0[mgnl:contentNode]
website:/hello-world/paragraphs/00/todos[mgnl:contentNode]
website:/hello-world/paragraphs/00/todos/0[mgnl:contentNode]
website:/hello-world/paragraphs/00/todos/00[mgnl:contentNode]

If I execute the same query using the JCR query tool in admin central with 'Result ItemType' nt:base i receive the following.

/hello-world/paragraphs/0/todos/MetaData
/hello-world/paragraphs/0/todos/0
/hello-world/paragraphs/00/todos/MetaData
/hello-world/paragraphs/00/todos/0
/hello-world/paragraphs/00/todos/00

Can you tell me what the MetaData nodes are ? Where they come from, how to avoid having them returned in my query ?
Rem: I can't see these 'MetaData' nodes in the JCR Browser in admin central.

thanks in advance

Nicolas

Well, you can find quite a bit of info in the JCR specs. Then I find  
this very useful:

And this sometimes helps too for the basics:
