java-Xerces-从字符串加载架构

作者:互联网

我想使用Xerces从字符串加载XML模式,但是直到现在,我只能从URI加载它:

final XMLSchemaLoader xsLoader = new XMLSchemaLoader();
final XSModel xsModel = xsLoader.loadURI(file.toURI().toString()); 

可用的加载方法:

XSLoader {
    public XSModel load(LSInput is) { }
    public XSModel loadInputList(LSInputList is) { }
    public XSModel loadURI(String uri) { }
    public XSModel loadURIList(StringList uriList) { }
}

是否可以从字符串加载XML模式?在我的上下文中,处理是在客户端完成的,因此无法使用URI方法.

谢谢.

解决方法:

我对您的问题不是特别熟悉,但是我从ProgramCreek找到了这个有用的代码段,该代码段演示了如何从LSInput对象(上面列出的第一个方法)中获取XSModel.也可以从输入流中加载XML模式.我稍微修改了代码以达到以下目的:

private LSInput getLSInput(InputStream is) throws InstantiationException,
    IllegalAccessException, ClassNotFoundException {
    final DOMImplementationRegistry registry = DOMImplementationRegistry.newInstance();
    final DOMImplementationLS impl = (DOMImplementationLS)registry.getDOMImplementation("LS");

    LSInput domInput = impl.createLSInput();
    domInput.setByteStream(is);

    return domInput;
}

用法:

// obtain your file through some means
File file;
LSInput ls = null;

try {
    InputStream is = new FileInputStream(file);

    // obtain an LSInput object
    LSInput ls = getLSInput(is);
} catch (FileNotFoundException e) {
    e.printStackTrace();
} catch (Exception e) {
    e.printStackTrace();
}

if (ls != null) {
    XMLSchemaLoader xsLoader = new XMLSchemaLoader();
    XSModel xsModel = xsLoader.load(ls);

    // now use your XSModel object here ...
}
