Hello,
I want to use the XPath statement ‘between’ in a query. It seems that XApplication only supports simple queries such as /node[childnode = date]. Is there a way to implement a more complex query such as /node[childnode between date_low, date_high]? Thanks in advance.
Cheers,
Karsten

Hello,

to check a range the Query Object Model of X-Application provides a QueryRange. It is a query item which uses <=,< and >=,> operators for filter expression. In your case the use of QueryRange would

/node[childnode >= date_low and childnode <= date_high]

To use the ?between? operator you could use a QueryFilter.

If the Query Object Model does not fit your requirements there is a way to create a cursor for documents directly. Use the following code:

// define how many document should be returned by on request.
int pagesize = 10;

// load the schema for your query.
Schema nodeSchema = Schema.read(workspace.getStore(), “node”, false);

// name which is used by the cursor to register the current document within the workspace
String name = ?myNodes?;

// create the cursor for query set
BusinessDocumentCursor bdc = new BusinessDocumentCursor (“/node[childnode between date_low, date_high]”, workspace, name, nodeSchema, pagesize);

I hope that this will help you to define your queries.

Bye,
Christian.
