src-resolve:无法将名称“ds:Signature"解析为“元素声明"组件 [英] src-resolve: Cannot resolve the name 'ds:Signature' to an 'element declaration' component

问题描述

我想使用 XSD 文件进行架构验证.当我将 XSD 文件导入 Eclipse 时，没有运行验证类，出现以下错误:

I want to do schema validation using an XSD file. When I import the XSD file to Eclipse, without running the validation class, I have the following error:

src-resolve:无法将名称ds:Signature"解析为元素"声明组件

src-resolve: Cannot resolve the name 'ds:Signature' to an 'element declaration' component

我对 XML 与 XSD 验证过程有点陌生.虽然我在谷歌上寻找过类似的问题，但我无法弄清楚这里出了什么问题.

I am kinda new to XML vs XSD validation process. Although I have looked for similar questions on google, I couldn't figure out what's wrong here.

XSD 文件如下:

 <?xml version="1.0" encoding="UTF-8"?>
    <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:xerces="http://xerces.apache.org"
        xmlns:xades="http://uri.etsi.org/01903/v1.3.2#" xmlns:ds="http://www.w3.org/2000/09/xmldsig#"
        xmlns:abc="http://abc.123.com" targetNamespace="http://abc.123.com"
        xmlns:xades141="http://uri.etsi.org/01903/v1.4.1#" elementFormDefault="qualified"
        attributeFormDefault="unqualified">
        <xs:import namespace="http://uri.etsi.org/01903/v1.3.2#" schemaLocation="XAdES.xsd"/>
        <xs:import namespace="http://uri.etsi.org/01903/v1.4.1#" schemaLocation="XAdESv141.xsd"/>
        <xs:import namespace="http://www.w3.org/2000/09/xmldsig#" schemaLocation="xmldsig-core-schema.xsd"/>
    <xs:complexType name="headerType">
        <xs:sequence>
            <xs:element name="doorNumber" type="xs:int"/>
            <xs:element ref="ds:Signature"/>
        </xs:sequence>
    </xs:complexType>

我应该如何修改 XSD 来修复这个错误?

How should I modify the XSD to fix this error?

推荐答案

如果您有 xmldsig-core-schema.xsd 与您的 XSD 位于同一目录中，<强>如果它与 此 XSD，那么您不应该收到关于解析 ds:Signature 失败的错误.

If you have xmldsig-core-schema.xsd in the same directory as your XSD, and if it is the same as this XSD, then you should not be getting an error about a failure to resolve ds:Signature.

因此，我怀疑您的导入失败，并且您丢失或忽略了如下警告:

Therefore, I suspect that your import is failing, and you're missing or ignoring a warning such as the following:

[警告] try.xsd:9:56: schema_reference.4: 读取架构失败文档xmldsig-core-schema.xsd"，因为 1) 找不到文档;2) 无法读取文件；3) 的根元素该文档不是 .

[Warning] try.xsd:9:56: schema_reference.4: Failed to read schema document 'xmldsig-core-schema.xsd', because 1) could not find the document; 2) the document could not be read; 3) the root element of the document is not <xsd:schema>.

试试这个 XSD 作为测试；它直接从 xmldsig-core-schema.xsd 的 URL 加载:

Try this XSD as a test; it loads directly from the URL for xmldsig-core-schema.xsd:

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
           xmlns:ds="http://www.w3.org/2000/09/xmldsig#"
           xmlns:abc="http://abc.123.com"
           targetNamespace="http://abc.123.com"
           elementFormDefault="qualified"
           attributeFormDefault="unqualified">
  <xs:import namespace="http://www.w3.org/2000/09/xmldsig#"
             schemaLocation="http://www.w3.org/TR/2002/REC-xmldsig-core-20020212/xmldsig-core-schema.xsd"/>
  <xs:complexType name="headerType">
    <xs:sequence>
      <xs:element name="doorNumber" type="xs:int"/>
      <xs:element ref="ds:Signature"/>
    </xs:sequence>
  </xs:complexType>
</xs:schema>

我已经测试了上述 XSD，发现它消除了您所看到的分辨率错误.

I've tested the above XSD and found that it eliminates the resolution error that you were seeing.
