Overview

PXStylesheetParser is responsible for making the first pass on CSS source. This pass generates expression trees for selectors. However, rule set bodies are mostly scanned only. The parser recognizes a declaration’s name (property name), but simply collects its value lexemes in a array for future processing, if needed.

PXStylesheetParser uses some simple strategies for error recovery. All errors are captured and attached to the stylesheet generated by the parse methods.

Tasks

  • – parse:withOrigin:

    Make a first pass parse of the specified source and return the results in a new stylesheet instance.
  • – parse:withOrigin:filename:

    Make a first pass parse of the specified source and return the result in a new stylesheet instance. This parse method allows the file name to be specified which is used to prevent @import cycles.
  • – parseInlineCSS:

    Treat the specified source as inline CSS, as if it were coming from a style attribute.
  • – parseSelectorString:

    Parse the specified source as a CSS selector only.
