针对嵌套WSDL中的模式验证XML文档:类型

Question

我有XML文件，我需要针对从Web服务检索的WSDL文件中嵌套<wsdl:types></wsdl:types>中嵌套的XSD进行验证。

<wsdl:types></wsdl:types>内部有几个<xs:schema> s。我正在使用Ruby Gem nokogiri加载XML文件并针对所述XSD进行验证，但是，运行程序时我会遇到以下错误：

Element '{http://schemas.xmlsoap.org/soap/envelope/}Envelope': No 
matching global declaration available for the validation root.

到目前为止，我已经提取了<xs:schema> S(所有4个(，然后将它们复制到schema.xsd文件中。

代码：

require 'rubygems'
require 'nokogiri'
def validate(document_path, schema_path)
  schema = Nokogiri::XML::Schema(File.read(schema_path))
  document = Nokogiri::XML(File.read(document_path))
  schema.validate(document)
end

validate('data.xml', 'schema.xsd').each do |error|
  puts error.message
end

因此，基本上我的schema.xsd中有多个<xs:schema> s，我认为这本身并不是一个问题，因为当我实例化schema对象时，nokogiri不会丢弃错误。

schema.xsd

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:tns="http://schemas.microsoft.com/2003/10/Serialization/" attributeFormDefault="qualified" elementFormDefault="qualified" targetNamespace="http://schemas.microsoft.com/2003/10/Serialization/">
  <xs:element name="anyType" nillable="true" type="xs:anyType"/>
  <xs:element name="anyURI" nillable="true" type="xs:anyURI"/>
  <!-- data in here -->
</xs:schema>
<!-- three more xs:schema tags removed for brevity -->

data.xml

<?xml version='1.0' ?>
<env:Envelope xmlns:env="http://schemas.xmlsoap.org/soap/envelope/">
  <env:Header />
  <env:Body>
    <CreatePerson xmlns="https://person.example.com/">
      <oMessageType xmlns:epa="http://schemas.datacontract.org/2004/07/whatever" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:array="http://schemas.microsoft.com/2003/10/Serialization/Arrays">
        <person:bodyField>
            <!-- data in here -->
        </person:bodyField>
        <!-- more data in here -->
      </oMessageType>
    </CreatePerson>
  </env:Body>
</env:Envelope>

是的，WSDL不是XSD scheam，因此您需要通过编程手动或自动提取模式部分。

这是示例代码，您需要重构并在代码中使用。
