Xstream + xpp combination of powerful gold

No need to generate DTD, useless configuration, no need to generate helper classes, fast. This is the combination of xstream and xpp. As we all know about xstream, XML pull parser is a high-speed method for parsing XML files, which is much faster than the traditional method (it is found that pull-based Parsing is now popular ). The following is an example of multiple usage methods. 1. The simplest way to useThis is too simple, so I will take the foll

EXML is included in the results shown in this article, but keep this in mind when interpreting performance differences.EXML uses an integrated parser to construct a document representation based on a text document. In addition to text, it does not provide any way to convert or convert from a DOM (or SAX2) to a SAX2 (or DOM) event stream. EXML is open source issued by Mind Electric under a restricted license that prohibits embedding it

localname is the same as that of "book", it means that a book object is parsed, and a new book object can be created, and localname is saved in tagname. Use attribute to obtain the value of the bookid. Characters is the content of the parsed text node. The saved tagname is compared with "name" and "price" at this time. If the tagname is the same, the bookname, the bookprice value is encapsulated. In this case, the tagname should be assigned a null value. Otherwise, when it is not empty, the sec
