Concurrent parsing and processing of HTML and JAVASCRIPT®

A computing device for executing a markup language, comprising:

• a memory;
• and
• a processor coupled to the memory, wherein the processor is configured with processor-executable instructions to perform operations comprising:
• receiving in the processor a request to load a web page;
• receiving markup language code associated with the requested web page, the markup language code including embedded scripting language code;
• parsing the received markup language code to generate parse data until a segment of scripting language code is encountered;
• packaging the encountered segment of scripting language code and parsing state information in an execution state package upon encountering the segment of scripting language code;
• storing the execution state package in a scripting language script queue;
• continuing parsing the received markup language code;
• obtaining the segment of scripting language code from the scripting language script queue;
• executing the obtained segment of scripting language code concurrent with continued parsing of the markup language code;
• determining whether markup language code generated from the execution of the obtained segment of scripting language code is well formed;
• when it is determined that the generated markup language code is well formed, storing the generated markup language code;
• and
• when it is determined that the generated markup language is not well formed:
• retrieving the parsing state information packaged in the execution state package;
• discarding parse data resulting from parsing of the markup language code after a point in the markup language code identified by the retrieved execution state package;
• and
• re-initiating parsing of the markup language code from the point in the markup language code identified by the retrieved execution state package.

A non-transitory storage medium having stored thereon processor-executable software instructions configured to cause a processor to perform operations for executing a markup language code, the operations comprising:

• receiving in the processor a request to load a web page;
• receiving markup language code associated with the requested web page, the markup language code including embedded scripting language code;
• parsing the received markup language code to generate parse data until a segment of scripting language code is encountered;
• packaging the encountered segment of scripting language code and parsing state information in an execution state package upon encountering the segment of scripting language code;
• storing the execution state package in a scripting language script queue;
• continuing parsing the received markup language code;
• obtaining the segment of scripting language code from the scripting language script queue;
• executing the obtained segment of scripting language code concurrent with continued parsing of the markup language code;
• determining whether markup language code generated from the execution of the obtained segment of scripting language code is well formed;
• when it is determined that the generated markup language code is well formed, storing the generated markup language code;
• and
• when it is determined that the generated markup language is not well formed:
• retrieving the parsing state information packaged in the execution state package;
• discarding parse data resulting from parsing of the markup language code after a point in the markup language code identified by the retrieved execution state package;
• and
• re-initiating parsing of the markup language code from the point in the markup language code identified by the retrieved execution state package.
