XML (Extensible Markup Language)

A tag-based textual formatting language document mark-up or data structuring

Based on SGML (Standard Generalised Markup Language) became international standard ISO 8879 in 1986

Standard from W3C (World Wide Web Consortium) recommendation XML version 1.0 (February 1998)

Extracting Data from Files using ezXML Text Gateway

MAKE %GOODS_INFO { GOODS_INFO [ NAME [$name], QUANTITY [$quantity] ]}MATCH { #ROW(+1) #COL(0) ~‘Product Name:’ (100b)? #EVAL($name, 50x) #ROW(+1) #COL(0) ~‘Quantity:’ (100b)? #EVAL($quantity, 20n)

}

IGNORE %BETWEEN_RECORDMATCH { #REJECT(~‘Customer ID’) #ROW(+1) #COL(0)

}

A rule named GOODS_INFO

XML message construction

Pattern in the text file to be matched

A sub-pattern to be matched

Data to be extractedfrom a matched pattern

A rule with no outputEfficient skipping drivenby matched pattern

Translating XML Data using ezXML Translation Engine

A hierarchy oftemplates reflectingthe structure of theinput message

A hierarchy oftemplates toconstruct theoutput message

Variable to hold matched data

Conclusions

A holistic approach that addresses the need of the whole development cycle

XML design becomes a part of application design right at the beginning

With ezXML Designer, designs can be formulated using only UML concepts

Just like data, designs need to be managed

With ezXML DTD Editor, designs can be changed as well as stored in and retrieved from either a file system or a database system

DOM and SAX approaches to XML application development is too low level

Significant productivity gain can be obtained using a higher level interface to XML

With ezXML Java API Generator, high level API can be generated for use by Java applications
