The previous article describes how to parse an XML file using groovy, and this article describes how to generate an XML file. Like parsing XML, groovy also offers two ways to Markupbuilder and Streamingmarkupbuilder. Generally speaking, Streamingmarkupbuilder is more professional and more complete in function. Their differences are somewhat similar to Dom and sax, which means that processing large XML files

If you want to retrieve variables from a complex nested data structure, velocity is used, but groovy is recommended because it is more convenient for computation, and gave me a general framework, which is still being explored ...... Put parameters in Map Public object executescript (string script, Map

Groovy tip 35 Regular Expression 4 We know that in regular expressions, some strings are used to express some special purposes. For example, "." represents all characters; "^" represents non-; and so on. When we see these usage, we can ask in turn, if "." represents all the characters, then what will be used to match "." In the string? To solve this problem, you must add "/" to the regular expression to match the original string. The following is a

Groovy exploration-adding constructors and static methods during the mop six Runtime Constructor is a method that we like to overload, because we encounter various situations when instantiating a class, such as in some situations, instances of a series of classes may have attributes with the same value. At this time, when instantiating an object, we do not want to inject these identical values into each object separately, this is a tedious task. A

The returned results may need to be verified during case construction. You can use the groovy script to complete this function. The specific steps are as follows: (1) Use the groovyutils provided by soapui to retrieve the returned XML message xmlholder Def policyutils = new COM. eviware. soapui. Support. policyutils (context) Def holder = policyutils. getxmlholder ("balancequery # response ") (2) Use XPath in xmlholder to obtain the returned f

Lisp is a simple and powerful language with a very simple syntax:(+ 1 2)The above meaning is: + is a method or function, 1, 2 is a parameter, fn=1+2, that is, the sum is evaluated, the result is: 3Double brackets are used to remind the interpreter to start and end.Previously wrote an article in Iteye to briefly explain how to write Lisp's interpreter:http://gyc567.iteye.com/blog/2242960It also draws a sketch to illustrate:Because Lexer ( lexical analyzer ) is the main job is to convert the progr

Because it is always so close to the bottom of the hardware that the excitement that began in the 96 is fading away. Programming in life is either a compilation or a C + + or Delphi. Ruby has been excited for a while now and it's groovy. The latter were always marching on the bones of the pioneers. To admire the martyrs is serious, but there is always laughter in life. Groovy's here. The first step is to get the latest Java Jdk:jdk-6u13-windows-i586

The map parameter is one of the most commonly used parameter types in the code of the Groovy language, and we often write the following code naturally: t.testMap(a:1) t.testMap(a:1,b:1) t.testMap(a:1,b:1,c:1) new Person(name:'Tom',sex:23) These are the uses of the map parameter. And so on, we also often want the list parameter to have the same function, for example, we have the following method with the list object as a parameter: class Testor2 { 　

We know that in addition to using hooks to intercept methods, we can also implement methods in various ways. For example, we can implement the method directly in the class, we can add the method through the Expandometaclass during the runtime, and we can add the method to an object separately by Expandometaclass during the run time. All of these ways of directly adding methods, if there is a hook, are to be intercepted by hooks. So, we can say that the system is a priority call hook. and the c

As we all know, in the groovy language, we can use the mop attribute to add properties or methods to the runtime. This addition includes two levels of additions: The first is to add a property or method to a class. That is, if we add a property or method to a class during the runtime, then all the objects instantiated by that class will have this property or method added later. Second, the second is to add a property or method to an object. That is

The interface type described here, in both the Java language and the groovy language, is of course both the base class type and the interface. The term "Dynamic of an interface type" refers to the dynamic addition of a method to a base class or interface during the runtime so that the base class and its subclasses, interface implementations, can access these methods. This feature has always been a feature of interest to me. Because we use a variety o

We talked about mop, that is, "Meta Object Protocol", is the class or object elements, such as names, methods, attributes, and so on, in the run-time of real-time changes, such as the modification method name, attribute name, dynamic increase methods, attributes and so on a class of programming collectively. For example, we have talked about the "InvokeMethod" and "methodmissing" two methods, can be used to enable us to dynamically in the runtime to add methods to a class, it is noteworthy that

Last night to help the old colleague solved a soapui code problem, a long time useless soapui, a lot of things are forgotten, today first summarize the groovy read propertiesFirst spit trough under soapui of Apidocs, I can hardly see what things, official website tips have so little use, but for a long time did not update, a lot of things can not find. And it's almost impossible to debug groovy code in SOAP

List:The list in groovy is similar to an array of Java, such as:def numbers = [1, 2, 3, 4]The groovy list uses the index operator [] to represent the element value, [] is the overload of the GetAt method of the list class, the usage and the character index get a substring similar, and the list can be 、-、 assignment, Mapping (MAP):Mapping is an unordered collection of key-value pairs that you are familiar wi
