cnd-parser

What is cnd-parser?

This is a small (nodejs/browserify) library for parsing CND-Strings (defined in jsr-170 and explained at jackrabbit).

This implementation doesn't support the full CND-syntax.

Limitations

• constraints and default values are not supported
• each property and childnode needs to be defined on one row
• shortcuts (like m for multiple) are not supported
• the library does no validation for nodetype, property or childnode options

Example

This example:

<ns = 'http://namespace.com/ns'>
[ns:NodeType] > ns:ParentType1, ns:ParentType2
  orderable mixin
  - ex:property (string) primary mandatory autocreated protected multiple version
  + ns:node (ns:reqType1, ns:reqType2) mandatory autocreated protected multiple version
[nt:resource] > mix:referenceable
  - jcr:encoding
  - jcr:mimeType mandatory
  - jcr:data (binary) mandatory
  - jcr:lastModified (date) mandatory ignore

can be parsed (in nodejs) like this:

cnd = cndParser.parseString('/* string here! */');
console.log(JSON.stringify(cnd.getNodeTypes(), null, 4));

Output:
