Methods (600, 700, 900), apparatuses and computer program products are disclosed for parsing and formatting a document encoded using a markup language in a memory-constrained environment. The structure (100) of the document is represented by a tree having one or more nodes (n1-n10). One method (600) includes the steps of, for a current one of the nodes, freeing memory occupied by any previously formatted one of the nodes upon which formatting of the current node, according to a set of formatting rules, is independent; and building a partial document tree (500) using the current node and remaining previously formatted nodes upon which formatting of the current node, according to the set of formatting rules, is dependent. Another method includes the steps of obtaining information about one or more nodes of the document using a lookahead parser, and formatting the one or more nodes using the obtained information.
