DOM has a name-space awareversion
API version of most key interfaces getAttributeNS(String nsURIString localName)
Example ldquohttpskatestowncomnsinvoicerdquo (ns URI) ldquoitemrdquo ldquotaxrdquo etc (local name wo prefix)
Requires the parser become name space aware
After
DocumentBuilderFactory factory=
DocumentBuilderFactorynewInstance()
insert
factorySetNamespaceAware(true)
Todays DOM exercise
Use DOM for invoice checker repeat last weeks exercise using a DOM parser instead
( Down load files InvoiceCheckerjava InvoiceCheckerDOMjava with ftpevarosenet)
Transform InvoiceCheckerDOMjava to read an invoice xml document which uses name spaces (Download skatextownInvoiceNSxml with ftpevarosenet)

Assignment 1
Todays exercise DOM parsing(Document Object Model W3C)
ONE-STEP parsing model
Most popular and widely used parser model
Builds the parse tree first before parsing
Easy to program with but takes up a lot of memory takes time to instantiate the parse tree
DOM parsing
Building a DOM parse tree Navigating and manipulating the DOM tree
Two important packages orgw3cdom javaxxmlparsers
httpjavasuncomwebservices Java API for XML Web Services (JAX-WS) Java Architecture for XML Binding (JAXB) Java API for XML Messaging (JAXM) gtgtgt Java API for XML Processing (JAXP) Java API for XML Registries (JAXR) Java API for XML-based RPC (JAX-RPC) SOAP with attachments API for Java (SAAJ) Java API for XML WS addressing (JAX-WSA) XML Web Services Security (XWSS)

Example ldquohttpskatestowncomnsinvoicerdquo (ns URI) ldquoitemrdquo ldquotaxrdquo etc (local name wo prefix)
Requires the parser become name space aware
After

Todays DOM exercise
Use DOM for invoice checker repeat last weeks exercise using a DOM parser instead
( Down load files InvoiceCheckerjava InvoiceCheckerDOMjava with ftpevarosenet)
Transform InvoiceCheckerDOMjava to read an invoice xml document which uses name spaces (Download skatextownInvoiceNSxml with ftpevarosenet)
