java - 使用 validator 针对 xsd 验证soap xml

Question

我想根据给定的xsd验证soap请求xml，请求可能很大，所以我不能只提取soap主体的内容并进行验证，而是进行基于流的验证。我已经为soap主体(请求部分)制作了xsd，并且它不包含有关soap header 的任何信息，因此验证失败，我所做的是将soap模式导入到我的xsd中，以便验证程序可以识别soap header 。它有效，但即使肥皂体不包含任何东西，验证也会成功。我们如何在 xsd 中指定肥皂体应至少包含特定元素？我修改后的xsd粘贴在下面。谢谢。

<?xml version="1.0" encoding="utf-8"?>
<xsd:schema attributeFormDefault="qualified" targetNamespace="urn:sample"
            xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:tns="sample">

尝试类似的操作:

SchemaFactory factory = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
FileInputStream fileInputStream = new FileInputStream(new File("Simple.xsd"));  
Schema schema = factory.newSchema(new StreamSource(fileInputStream));  
Validator val = schema.newValidator(); 
FileInputStream fileInputStream2 = new FileInputStream(new File("Input.xml"));  
val.validate(new StreamSource(fileInputStream2));
