Intro

  • Not as mature as querying relational databases
  • No underlying algebra
  • XPath : Path expressions and conditions
  • XSLT : XPath + Transformations, output processing
  • XQuery : XPath + full featured query language
  • XLink, XPointer : Use XPath as a component

XPath

  • Think of XML as a tree
  • Expressions in XPath as navigations down/across the tree with conditions
