scala.xml.parsing

MarkupParser

trait MarkupParser extends MarkupParserCommon with TokenTests

An XML parser.

Parses XML 1.0, invokes callback methods of a MarkupHandler and returns whatever the markup handler returns. Use ConstructingParser if you just want to parse XML to construct instances of scala.xml.Node.

While XML elements are returned, DTD declarations - if handled - are collected using side-effects.

    The library and compiler parsers had the interesting distinction of different behavior for nextch (a function for which there are a total of two plausible behaviors, so we know the design space was fully explored.) One of them returned the value of nextch before the increment and one of them the new value.

    The library and compiler parsers had the interesting distinction of different behavior for nextch (a function for which there are a total of two plausible behaviors, so we know the design space was fully explored.) One of them returned the value of nextch before the increment and one of them the new value. So to unify code we have to at least temporarily abstract over the nextchs.
