W3C: XQuery, XSLT 2 e XPath 2
Por Cosme Faé | 26 de Janeiro de 2007
A W3C publicou 8 novos padrões de XML para Data mining, transformação de documentos e computação de web services para base de dados. “Mais de 1000 comentários de desenvolvedores ajudaram a garantir implementações de configuração de tecnologia de base de dados”, disse Jim Melton (Oracle). XSLT tranforma documentos em diferente markups ou formatos”. XML Query pode fazer procuras, queries e juntar coleções de documentos. Usando as expressões XPath, XSLT 2 e XQuery podem operar em documentos xml, base de dados xml, base de dados relacionais, sistemas de busca e repositórios de objeto.
