Example

Find all customers

var results = $XmlRepository.Query('//Customer');
$Xml.InnerXml( 'Customer', results.join() );

Example

Find customer by id

var results = $XmlRepository.Query('//Customer[Id=$id]', {
   id : $Xml.Evaluate('CustomerId')
 });
$Xml.InnerXml( 'Customers', results.join() );

If you want to query the database of a process, you can use the collection keyword. You have to give the name of the database which is a GUID. For process databases, you can have that GUID by $Instance.ProcessId.

Example

Querying process database

var results = $XmlRepository.QueryXml('collection("49551ed3-6229-408a-aaaa-eb510463acad")//Customer[Id=$id]', {
id : $Xml.Evaluate('CustomerId')
});
$Xml.InnerXml( 'Customers', results[0].Evaluate('Id') );
