XALAN寄存器扩展功能，如SAXON [英] XALAN register Extension Function like in SAXON

问题描述

我想用XALAN通过XSLT转换XML。现在我想使用扩展函数，这个函数必须像在SAXON中一样添加到JAVA源中：

i want to transform a XML by XSLT with XALAN. Now i want to use a extension-function, this function have to be added in JAVA source like in SAXON:

方法：

TransformerFactory tFactory = TransformerFactory.newInstance();
Configuration c = ((net.sf.saxon.TransformerFactoryImpl) tFactory).getConfiguration();
c.registerExtensionFunction(new FooExtension());

FooExtension：

FooExtension:

public class FooExtension extends ExtensionFunctionDefinition {

    private static final long serialVersionUID = -8143237239412146617L;

    @Override
    public SequenceType[] getArgumentTypes() {
        return new SequenceType[] { SequenceType.EMPTY_SEQUENCE };
    }

    @Override
    public StructuredQName getFunctionQName() {
        return new StructuredQName("ns", "http://namespace", "generate-guid");
    }
}

但它在XALAN中是如何工作的？？？FunctionTable？ ，？FunctionResolver？，？URIResolver？），我必须按来源做，我不允许在XSLT中添加类。

But how does it works in XALAN (?FunctionTable?, ?FunctionResolver?, ?URIResolver?) , i have to do it by source, i'm not allowed to add class in XSLT.

谢谢!!
