Analysis of text and construction of parse trees

Relationships

Illustration

See Contribution:haskellParsec for an extensive illustration.

Here is a simple illustration based on the assumed I/O behavior of parsing Java code.

Input of parsing: text

Consider the following textual representation of a Java statement, subject to Java's concrete syntax.

x = 42

Output of parsing: tree

Here is the corresponding parse tree, assuming some XML-based representation for abstract syntax:

<assign>
  <lhs>
    <id>x</id>
  </lhs>
  <rhs>
    <constant>42</constant>
  </rhs>
</assign>
