Obtaining Rendering Co-ordinates Of Visible Text Elements

A computer program comprising a set of computer-readable instructions adapted, when executed on a computer device, to cause said computer device to obtain the rendering co-ordinates of visible text elements on a web page represented by an input data structure comprising a plurality of text nodes, each of which represents a text element on the web page, by a method comprising;

• a) using said computer device, wrapping each of the plurality of text nodes in a pair of mark-up language tags;
• b) using said computer device, obtaining the co-ordinates of a bounding rectangle for each text node using the mark-up language tags;
• c) using said computer device, attaching an attribute specifying the co-ordinates of the bounding rectangle to each text node;
• and
• d) using said computer device, determining whether each text node is invisible, and if it is, excluding it from an output data structure comprising the plurality of text nodes and attached attributes.

A computer-readable medium having computer-executable instructions stored thereon that, if executed by a computer device, cause the computer device to obtain the rendering co-ordinates of visible text elements on a web page represented by an input data structure comprising a plurality of text nodes, each of which represents a text element on the web page, by a method comprising;

• a) using said computer device, wrapping each of the plurality of text nodes in a pair of mark-up language tags;
• b) using said computer device, obtaining the co-ordinates of a bounding rectangle for each text node using the mark-up language tags;
• using said computer device, attaching an attribute specifying the co-ordinates of the bounding rectangle to each text node;
• and
• d) using said computer device, determining whether each text node s invisible, and if it is, excluding it from an output data structure comprising the plurality of text nodes and attached attributes.
