A computer implemented method and apparatus for extracting localizable content from an article. The method comprises accessing a page content tree comprising a plurality of nodes; generating a set of all properties for each node in the plurality of nodes of the page content tree; accessing a localization tree comprising a global set of localizable properties of nodes; generating a set of localizable properties from the localization tree for nodes that match nodes of the page content tree; performing an intersection of the set of all properties for each node of the page content tree and the set of localizable properties; and extracting a value for each property in the intersection.
