    SPaC (short for "Streaming Parser Combinators") is a library for building stream consumers in a declarative style, specialized for tree-like data types like XML and JSON.

    SPaC (short for "Streaming Parser Combinators") is a library for building stream consumers in a declarative style, specialized for tree-like data types like XML and JSON.

    Many utilities for handling XML and JSON data involve parsing the entire "document" to some DOM model, then inspecting and transforming that model to extract information. The downside to these utilities is that when the document is very large, the DOM may not fit in memory. The workaround for this type of problem is to treat the document as a stream of "events", e.g. "StartElement" and "EndElement" for XML, or "StartObject" and "EndObject" for JSON. The downside to this workaround is that writing code to handle these streams can be complicated and error-prone, especially when the DOM is complicated.

    SPaC's goal is to drastically simplify the process of creating code to handle these streams.

    This package contains the "core" SPaC traits; Parser, Transformer, Splitter, and ContextMatcher.

    See the xml and json subpackages (provided by the xml-spac and json-spac libraries respectively) for specific utilities related to handling XML and JSON event streams.

    This package provides extensions to the core "spac" library which allow for the handling of XML data.

    This package provides extensions to the core "spac" library which allow for the handling of XML data.

    Rather than creating explicit classes that extend Parser, Transformer, and Splitter, this package provides type aliases and implicit extensions. For example, XmlParser[A] is just a type alias for Parser[XmlEvent, A], and XmlParser is just a call to Parser[XmlEvent].

    Three main Parser methods are added to Parser[XmlEvent] via the XmlParserApplyOps implicit class:

    • XmlParser.forText - for capturing raw text
    • XmlParser.attr - for capturing mandatory attributes from elements
    • XmlParser.attrOpt - for capturing optional attributes from elements

    One main Splitter constructor method is added to Splitter via the XmlSplitterApplyOps implicit class:

    • Splitter.xml - for creating splitters based on an inspection of an "element stack"

    Three main Splitter member methods are added to Splitter[XmlEvent, C] via the XmlSplitterOps implicit class:

    • .attr - alias for .joinBy(XmlParser.attr(...))
    • .attrOpt - alias for .joinBy(XmlParser.attrOpt(...))
    • .text - alias for .joinBy(XmlParser.forText)

    A DSL for creating xml-specific ContextMatchers is provided to make it more convenient to call Splitter.xml. For example:

    Splitter.xml("things" \ "thing").attr("foo").parseToList

    Can be used to capture a list of the "foo" attributes in the <thing> elements in

    <things>
   <thing foo="hello" />
   <thing foo="Goodbye">
      <extra>junk</extra>
   </thing>
</thing>

  1. def apply(stack: IndexedSeq[ElemStart], offset: Int, avail: Int): Option[Unit]

    The main context match method.

    The main context match method.

    Inspects the elements in the XML "tag stack", which is essentially a List[StartElement], but for performance reasons is represented as an array with an "offset" index and a number of available elements from that offset. If the elements correspond to a context value of A, the implementation must then pass the remaining elements of the stack to the next matcher, i.e. by calling next(stack, offset + numConsumed, avail - numConsumed).

    The difference between this method and applyChained is the lack of the next parameter; in this method, the current matcher is assumed to be the end of the chain.

    stack

    A reference to the complete XML "tag stack". Note that the responsibility of this method is limited to a *slice* of this value, as defined by offset and avail.

    offset

    The index of the first element to be considered by the matching logic. From this method's point of view, the "first" element in the stack is actually at stack(offset)

    avail

    The number of elements available in the stack starting from the offset.

    returns

    The underlying context match method.

    Inspects the elements in the XML "tag stack", which is essentially a List[StartElement], but for performance reasons is represented as an array with an "offset" index and a number of available elements from that offset. If the elements correspond to a context value of A, the implementation must then pass the remaining elements of the stack to the next matcher, i.e. by calling next(stack, offset + numConsumed, avail - numConsumed).

    The next matcher is necessary in order to support non-greedy matchers, e.g. ContextMatcher.variableLength, a.k.a. **. Without a reference to the next matcher in the chain, matcher implementations would be forced to pick a fixed number of elements for matching, never knowing that the overall match could have succeeded if they had consumed some additional elements.

    This member is added by an implicit conversion from XmlSplitterOps[C] toElemContextMatcher[Unit] performed by method elem in io.dylemma.spac.xml.This conversion will take place only if an implicit value of type AsQName[XmlSplitterOps[C]] is in scope.
