11. A handheld electronic apparatus, comprising: a touch display; a storage unit, configured to store a plurality of program instructions; a parsing unit, configured to parse a content of a document; and a processing unit, coupled to the touch display, the storage unit and the parsing unit, and configured to execute the program instructions to execute a parsing procedure, comprising: activating a browser to download the document from a webpage for displaying the content of the document, wherein the browser supports a text parsing function; disabling the text parsing function and parsing the content of the document according to a markup language rule to generate an object parsed result; enabling the text parsing function and removing the object parsed result when a touch event is detected; parsing the content to find out text groups according to a preset pattern database and re-parsing the content of the document according to the markup language rule to generate a full parsed result when the touch event is detected and after removing the object parsed result, wherein the preset pattern database comprises a plurality of specific patterns, and a format of each of the text groups conform to one of the specific patterns; determining whether a touch coordinates matches a corresponding position of a specific text group of the text groups; and performing a corresponding action related to the specific text group when the touch coordinates matches the corresponding position of the specific text group.
14. The handheld electronic apparatus as claimed in claim 11 , wherein the parsing procedure further comprises: detecting a touch up event after parsing the content to find out the text groups; and extracting the touch coordinates of the touch up event.
