最近为了验证一个xml文件的合法性，犹豫约束较多，包括数据类型、唯一约束，类似数据库外键的约束，如果这些都使用java代码去验证的话，显然会有很大的工作量，其次，如果xml文件发生变更，代码也会需要做很大的变更，所以，我首先想到的是使用xml schema 对文件进行验证，使用Altova.XMLSpy.Enterprise.2010编写完xsd文件，并用在该软件上使用刚编写完的xsd验证目标xml文件的结果非常完美。接着着手开始编写java代码：
import java.io.File;
import javax.xml.XMLConstants;
import javax.xml.transform.Source;
import javax.xml.transform.stream.StreamSource;
import javax.xml.validation.Schema;
import javax.xml.validation.SchemaFactory;
import javax.xml.validation.Validator;
import org.xml.sax.SAXException;
public class Main {
/**
* @param args
*/
public static void main(String[] args) {
File f=new File("E:/git/SkybilityHA/doc/cluster.xsd");
try {
Source xmlFile = new StreamSource(new File("E:\\git\\SkybilityHA\\doc\\cluster.xml"));
SchemaFactory schemaFactory = SchemaFactory
.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
Schema schema = schemaFactory.newSchema(f);
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());
}
} catch (Exception e1) {
e1.printStackTrace();
}
}
}
运行代码，问题出来了，结果验证有误，错误信息如下：
file:/E:/git/SkybilityHA/doc/cluster.xml is NOT valid
Reason: Key 'resourceBootorderFK' with value '28' not found for identity constraint of element 'resources'.
为什么两次验证结果不一致？是Altova.XMLSpy.Enterprise.2010错了，还是java错了，于是又找了一个在线验证网站（http://www.freeformatter.com/xml-validator-xsd.html）对结果进行验证，结果仍然是不通过。显然Altova.XMLSpy.Enterprise.2010的结果验证不正确。为了方便测试xsd，我又下载了Oxygen.XML.Editor.v15来进行xsd的编辑，xsd文件内容如下：

最初以为是下面一段代码中的selector元素的xpath不正确：
<!--定义节点的ID做为外键--> <xsd:key name="nodesNodePk"> <xsd:selector xpath="./nodes/node"/> <xsd:field xpath="@id"/> </xsd:key> <!--################################################################# subnets约束 #############################################################################--> <!--定义子网的节点必须是在nodes中定义过的节点--> <xsd:keyref name="subnetsSubnetFK" refer="nodesNodePk"> <xsd:selector xpath="./subnets/subnet/node"/> <xsd:field xpath="@id"/> </xsd:keyref>
可是几经验证，xpath是没有问题的，于是求助谷歌，查了一个晚上加一个上午，终于看到了这一段：
The first error I get on this is that you've constrained "Type" to be
singles or doubles, but the actual value is "Those are football matches".
The next error appears to be because the values you are using for keys have
variable numbers of leading and trailing spaces. If you want these
normalized, don't use the type xs:string.
The next two errors are because your key definitions and references don't
match: your Member elements are matching the content of the Name element,
not the @id attribute, and the Team elements are matching on the @Name
attribute, not the @id attribute.
It always helps, incidentally, to say which product you are using. Then you
might get someone looking at it who is familiar with the error messages
produced by that product.
英语不是很好，看的懵懵懂懂的，但是 don't use the type xs:string.这句话给了我一个提醒，我在定义nodes下的node的id属性时使用了type=“PLUS”这个我自定义的数据类型，而在subnets下的subnet下的node的id中却没有使用type定义属性值的类型，这会导致验证时把它的值当作xs:string或者其他什么基本类型来处理，反正不会是PLUS类型，这就导致了虽然值看起来一样，但是因为类型不一样，而不能找到引用的值而验证错误。如果也为该id设置type=“PLUS”，问题完美解决。
