Source code analysis of self-made XML Parser First, let's determine the requirements: (1) We want it to parse the XML string into a JSON object. (2) At least compatible with Firefox and IE. (3) This tool class should be a singleton. Code: /** * Parse XML into a JSON object * The string can be directly parsed into XML * You can also Parse XML file objects obtained through Ajax requests. * Main compatibility: IE, Firefox, and opera, which cannot be run

The strength of vs gives developers a good development experience. We can quickly locate a method in the CS file, it often brings us a pleasant development process when we modify code or extend functions, but this is obviously not done in Js. With the popularity of rich clients, the use of js in Web development is becoming more and more powerful. It is precisely because, with the development, there are more and more JS methods in a file, at the end of the day, it will be difficult to locate the

This is a creation in Article, where the information may have evolved or changed. Full text link:https://github.com/json-iterator/go-benchmark The aim is not to sell json-iterator. Instead, it proves that json-iterator is no slower than the rest of the library, so that you can put the spit point in other ways: For example, the feature is not complete, the API is not friendly. The re-inventing of the JSON parser is because it is often necessary to deal

This parser is dedicated to researching as a personal hobby. , Lasted for a long time, during which a lot of things occurred. I stayed in Shanghai for a long time And the project is named wittiness. Project purpose:Build a Web Information excavator to efficiently and conveniently To capture the required information. Build idea is: Parse the HTML Tag --> build a hierarchical object --> query to obtain the object that carries the required informati
