Jaxp xml解析&验证而不写入文件
我有一个 JMS 消息传递应用程序，用于读取和写入 MQ 队列。消息数据是字符串形式和 xml 格式（减去 xml 版本等普通标头标记）。我正在寻找读入、写出和验证 xsd 模式的最佳方法，但是我遇到的示例都讨论了如何处理文件。
有没有办法（有教程）获取 xml 字符串；读入并验证它，并对我创建的 xml 字符串执行相同的操作，验证并写出而不写入磁盘？
将不胜感激任何指点。
I've a JMS messaging app thats reading and writing to MQ queues. The message data is string form and in xml format (minus the normal header markers like the xml version etc). I'm looking at the best ways to read in, write out and validate against an xsd schema however the examples I'm coming across all talk about working with files.
Is there any way (tutorials out there) to take an xml string; read it in and validate it and also do the same for an xml string I create validate and write out without writing to disk?
Would appreciate any pointers.

查看 Java SE 中的 javax.xml.validation API，特别是用于根据 XML 模式验证 XML 内容的 Validator 类：
Check out the javax.xml.validation APIs in Java SE, in particular the Validator class which is used to validate XML content against an XML schema:
对字符串使用 StringReader，将读取器传递给 JAXB 方法以读取内容。
Use a StringReader on the strings, pass the reader to the JAXB methods to read the contents.
谢谢大家，我设法用以下内容解决了这个问题。
马歇尔：
JAXBContext jaxbContext = JAXUtility.getContext(packageLocation);
StringWriter sw = new StringWriter();
Marshaller m = jaxbContext.createMarshaller();
m.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, Boolean.TRUE);
if (o instanceof UnadvisedDeal) { m.marshal((UnadvisedDeal) o,sw);
UnMarshall:
JAXBContext jaxbContext = JAXUtility.getContext(packageLocation);
解组器 um = jaxbContext.createUnmarshaller();
ud = (UnadvisedDeal) um.unmarshal(new StringReader(sw.toString()));
不过还是谢谢你的帮助
thanks folks I managed to sort this one out with the following.
Marshall:
JAXBContext jaxbContext = JAXUtility.getContext(packageLocation);
StringWriter sw = new StringWriter();
Marshaller m = jaxbContext.createMarshaller();
m.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, Boolean.TRUE);
if (o instanceof UnadvisedDeal) { m.marshal((UnadvisedDeal) o,sw);
UnMarshall:
JAXBContext jaxbContext = JAXUtility.getContext(packageLocation);
Unmarshaller um = jaxbContext.createUnmarshaller();
ud = (UnadvisedDeal) um.unmarshal(new StringReader(sw.toString()));
thanks for the help though
