我試圖根據XML模式文件驗證XML文件,並且已下載了https://code.google.com/p/xerces-for-android/庫以使XML模式驗證正常工作,並且我已將該項目創建爲庫。我無法使其正常工作,並且出現'FileNotFoundException'錯誤,如果有人可以看到我做錯了什麼,或者我需要做些什麼才能使其工作,那麼請你能幫助我。使用xerces for Android進行XML模式驗證
下面是代碼:
public void xmlValidator() throws IOException, SAXException
{
Source schemaFile = new StreamSource(new File("device_description_schema.xsd"));
Source xmlFile = new StreamSource(new File("device_description.xml"));
SchemaFactory schemaFactory = new XMLSchemaFactory();
Schema schema = schemaFactory.newSchema(schemaFile);
Validator validator = schema.newValidator();
try {
validator.validate(xmlFile);
System.out.println(xmlFile.getSystemId() + " is valid");
} catch (SAXException e) {
System.out.println(xmlFile.getSystemId() + " is NOT valid");
System.out.println("Reason: " + e.getLocalizedMessage());
}
}
這裏是logcat的錯誤:

我只有存儲的文件n我的項目文件夾res/raw /下。我覺得我在這裏稍微做錯了一件事,它正在設備上尋找文件,顯然它不在那裏。我應該如何解決這個問題? –
請檢查我的編輯 –
我試過了,它不會檢測到原始文件夾中的文件。我應該嘗試再次創建文件夾還是有另一種方式? –
