Infrastructure: I'm using JAVA 1.5 and this is mandatory. But i can load any external lib so no problem.

Problem:

I have an XML file recived via "an external channel" and I can use it as InputStream

if someone need to get the same, could use:

InputStream is = new FileInputStream(file);

I need to validate the XML against XSD that has neasted XSD 

<?xml version="1.0" encoding="UTF-8"?>

           xmlns:BODY="urn:CBI:xsd:CBIBdySDDReq.00.00.06" 
           xmlns:HTRT="urn:CBI:xsd:CBIHdrTrt.001.07" 
           xmlns:HE2E="urn:CBI:xsd:CBIHdrSrv.001.07" 
           xmlns:SGNT="urn:CBI:xsd:CBISgnInf.001.04"

            </xs:element>
        </xs:sequence>
    </xs:complexType>
</xs:schema>

So I have a brunch of XSD file.

A chunk XML file is this

<?xml version="1.0" encoding="UTF-8"?>
<MSG:CBISDDReqPhyMsg xmlns:MSG="urn:CBI:xsd:CBISDDReqPhyMsg.00.00.06"
    xmlns:HTRT="urn:CBI:xsd:CBIHdrTrt.001.07" xmlns:HE2E="urn:CBI:xsd:CBIHdrSrv.001.07"
    xmlns:BODY="urn:CBI:xsd:CBIBdySDDReq.00.00.06" xmlns:LMSG="urn:CBI:xsd:CBISDDReqLogMsg.00.00.06"
    xmlns:SGNT="urn:CBI:xsd:CBISgnInf.001.04" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
    <MSG:CBIHdrTrt>
        <HTRT:IdCBISndrf>0000636J</HTRT:IdCBISndrf>
        <HTRT:IdCBIRcvrf>0000641V</HTRT:IdCBIRcvrf>
        <HTRT:SrvNm>INC-SDDC</HTRT:SrvNm>
        <HTRT:IdMsgTrt>
            0000636JP12312111154007381042010010000636J000000636J0000641V0
        </HTRT:IdMsgTrt>

So i need to validate the XML against CBISDDReqPhyMsg.00.00.06. So i know only at runtime against wich xml to use. Example another file could load CBISDDReqPhyMsg.00.00.05

I have two major problem

1) I need to obtain the xsd file name from XML and XML could be BIG 1/2GB (stax/sax are a nice solution)

2) I need to load the xsd from a jar because the whole app cannot have access to the file system.

For validation i prefer a system like http://www.edankert.com/validate.html

I read about include in this answer Problem validating an XML file using Java with an XSD having an include

But using the loader i can't obtain the infos about file.

Some idea?

我有两个主要问题

1) 我需要从 XML 中获取文件名，XML 可能是 BIG 1/2GB

2）我需要从 jar 加载 xsd，因为整个应用程序无法访问文件系统。

1.) 文件名不在 XML 中...您应该通过其他方式（用户输入、硬编码等）知道 XML 的文件名是什么。如果您有一个仅包含 XML 文件的目录，则可以对这些文件运行循环。一些伪代码：

for(getNextFile)
{
    if(xmlValidationWithXSD(nextFile))
        //passed validation
    else
        //failed validation
}

我通常运行脚本将所有 XML 文件从一个位置移动到仅 XML 文件夹。

2.) 我相信 StreamSource 允许你这样做。这是我最近所做的：

            public static boolean xmlValidationWithXSD(String xmlLocation){
                Source xmlFile = new StreamSource(new File(xmlLocation));

                 //IMPORTANT:  Here is what you need.  Multiple XSDs (that relate to each other) AND getResource will access form .jar files
                //Treat XSD as resource found in the class path, assume that the full package name is passed in xsdLocation
                Source schemaFileSource1 = new StreamSource(BenefitEnrollmentRequestFileUtil.class.getResource(NEW_XSD_FILE_RESOURCE1).toString());
                Source schemaFileSource2 = new StreamSource(BenefitEnrollmentRequestFileUtil.class.getResource(NEW_XSD_FILE_RESOURCE2).toString());
                Source[] schemaFileSources = {schemaFileSource1, schemaFileSource2};  


                SchemaFactory schemaFactory = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);

                try {
                    Schema schema = schemaFactory.newSchema(schemaFileSources);
                    Validator validator = schema.newValidator();
                    validator.validate(xmlFile);
                    return true;
                } catch (SAXException e) {
                    LOGGER.debug(xmlFile.getSystemId() + " is NOT valid", e);
                    LOGGER.debug("Reason: " + e.getLocalizedMessage());
                } catch (IOException e) {
                    LOGGER.debug(xmlFile.getSystemId() + " is NOT valid", e);
                    LOGGER.debug("Reason: " + e.getLocalizedMessage());                 
                }
                return false;
            }

在 jar 文件中引用 XSD 架构

使用带有包含包含的 XSD 的 Java 验证 XML 文件时出现问题

编辑：

文件之间的关系是第一个标签中包含的列表我有要使用的 xsd 列表，第一个 xsd 是与第一个标签具有相同名称的那个

<MSG:CBISDDReqPhyMsg xmlns:MSG="urn:CBI:xsd:CBISDDReqPhyMsg.00.00.06" xmlns:HTRT="urn:CBI:xsd:CBIHdrTrt.001.07" xmlns:HE2E="urn:CBI:xsd:CBIHdrSrv.001.07" xmlns:BODY="urn:CBI:xsd:CBIBdySDDReq.00.00.06" xmlns:LMSG="urn:CBI:xsd:CBISDDReqLogMsg.00.00.06" xmlns:SGNT="urn:CBI:xsd:CBISgnInf.001.04" xmlns:xsi="w3.org/2001/XMLSchema-instance">;

你不能读第一行，然后提取数据吗？使用 FileReader/DOM（如果您只是阅读一行，它不应该太慢）只是为了检索这一行。然后解析字符串。创建一个 ArrayList 并添加您提取的每个单独的部分。

就效率而言，检查一下：
