Class wwXML (Low Level Methods)

The low level methods of this class make it possible to build custom XML and string together multiple objects and cursors into a single XML document. There are two sets of routines for both cursor and object creation imports consisting of to export and two import routines. Each routine deals with one individidual object block (the structure or the data) and can be exported and parsed individually.

Output Methods

  • CreateDataStructureXML
  • CreateCursorXML
  • CreateObjectStructureXML
  • CreateObjectXML
  • CreateArrayXML
  • CreateCollectionXML


Input Methods

  • ParseXMLToCursor
  • BuildCursorFromXML
  • ParseXMLToObject
  • BuildObjectFromXML
  • ParseXMLToCollection
  • ParseXMLToArray

Class Members

MemberDescription

BuildCursorFromXML

Low Level Input Method

o.BuildCursorFromXML(loDataElement,lcAlias)

BuildObjectFromXML

Low Level Input Method

o.BuildObjectFromXML(loXMLObjectStructureElement)

CreateADOXML

Creates an XML fragment from an ADO recordset.

o.CreateADOXML(loRS, lcName, lcRowName, lnIndent)

CreateArrayXML

This method is used internally to parse object arrays. This low level method is specialized and only works with one dimensional arrays at this time.

o.CreateArrayXML(@laArray, lcName, lcRow, lnIndent)

CreateCollectionXml

This low level method creates Xml for a collection.

o.CreateCollectionXml(loCollection, lcName, lcRow, lnIndent)

CreateCursorFromSchema

Creates a cursor from a Schema definition in wwXML's schema format.

o.CreateCursorFromSchema(loSchema,lcAlias)

CreateCursorXML

Low Level Output Method

o.CreateCursorXML(lcName, lcRowName, lnIndent)

CreateDataStructureDTD

This method creates a DTD from the currently active Alias's data structure. The DTD generated is not complete in that it lacks the DocType and top level document root definition. This is so you can string together multiple cursors or objects in a single DTD.

o.CreateDataStructureXML(lcName, lcRowName, lnIndent, loRS)

CreateDataStructureSchema

Creates a Schema string from the currently active cursor/alias. The schema is generated as separate schema string.

o.CreateDataStructureSchema(lcName, lcRowName, loRS)

CreateObjectStructureDTD

Low Level Output Method

o.CreateObjectStructureDTD(oObject, cName)

CreateObjectStructureSchema

Creates a schema for a single level object.

o.CreateObjectStructureSchema(loObject, lcName, lnRecurseType)

CreateObjectStructureXML

Low Level Output Method

o.CreateObjectStructureXML(loObject, lcName, lnIndent)

CreateObjectXML

Low Level Output Method

o.CreateObjectXML(loObject, lcName, lnIndent)

ParseADOXMLToCursor

Low level method that parses the content of an ADO XML recordset to a VFP cursor. Cursor must already exist and the parameter passed in must point at the rows XML DOM collection when passed in.

o.ParseADOXMLToCursor(loDataElement)

ParseXmlToArray

Parses an XML representation to an Array.

o.ParseXmlToArray(loXmlNode,@laArray)

ParseXMLToCollection

This low level method imports a collection from an XML Node that follows a specific collection schema.

o.ParseXMLToCollection(loXmlNode,loCollection)

ParseXMLToCursor

Low Level Input Method

o.ParseXMLToCursor(oXMLCursorNode)

ParseXMLToObject

Low Level Input Method

o.ParseXMLToObject(loObjectElement, loObject, llParseCaseInsensitive)
