The DOM definition leverages the interface and inheritance of different components of an XML document. This gives developers the advantage of using a common interface for several different types of components, but adds complexity to the API. Because the DOM is language-independent, the interface does not need to take advantage of public Java components, such as the collections class.
This article covers two DOM implementations: Crimson and Xerces

You can link to the download page from the resources section at the bottom of this page to get the complete code for all samples. The download version of the sample includes a test driver and some added code to check the operations of different models by calculating the number of elements, deletions, and additions.
Even if you don't want to use the DOM implementation, it's worth browsing for a descrip

The example is as follows: When I used show InnoDB status to check the engine status, I found a deadlock problem: * ** (1) transaction: Transaction 0 677833455, active 0 sec, process no 11393, OS thread ID 278546 starting index read MySQL tables in use 1, locked 1 Lock wait3 lock struct (s), heap size 320 MySQL thread ID 83, query ID 162348740 dcnet03 dcnet searching rows for update Update tsk_task set status_id = 1064, update_time = now () Where status_id = 1061 and mon_time

Recently, in the project development process, encountered the database deadlock problem, in the process of solving the problem, the author of the MySQL InnoDB engine lock mechanism understanding gradually deepened.
The case is as follows:
The deadlock problem was found when using show InnoDB status to check engine state:

First of all we need to understand what CODEC means. It is Coder + Decoder = Codec, which is the encoder decoder. That is, the encoder is also the decoder.Website address: http://commons.apache.org/proper/commons-codec/Apache Commons Codec (TM) software provides implementations of common encoders and decoders such as Base64, Hex, Phonetic and URLs.The main supply is Base64, Hex, Phonetic and URLs, such as e
