验证 Google 原子提要
Validating a Google atom feed
我在尝试根据 Google Atom 提要验证 XML 文档时遇到以下错误。
Error - Line 8, 10: org.xml.sax.SAXParseException; lineNumber: 8;
columnNumber: 10; cvc-complex-type.2.4.a: Invalid content was found
starting with element 'g:brand'. One of '{"xxx..w3.org/2005/Atom":id,
"xxx.w3.org/2005/Atom":title, ".w3.org/2005/Atom":link,
"xxx.w3.org/2005/Atom":brand}' is expected.

但是，即使使用这个 XSD 来验证您的 XML 仍然会导致如下错误：
[Error] feed.xml:12:14: cvc-complex-type.2.4.c: The matching wildcard
is strict, but no declaration can be found for element 'g:brand'.
Google 基础命名空间
要消除与 http://base.google.com/ns/1.0 Google Base namespace extensions 相关的错误，您有两个选择：
将 Google 基础 XSD 导入 Atom XSD:
<xs:import namespace="http://base.google.com/ns/1.0"
schemaLocation="base-google.xsd"/>
这里的挑战是 (a) 与 http://base.google.com/ns/1.0 命名空间关联的 XSD 似乎并不存在于众所周知的官方位置，以及 (b) XSD可能不会被维护。我找到了一个 here。 [如果有人知道更官方或更新的 Google Base XSD，请发表评论，我会更新 link。]
松开xsd:any/@processContents="strict"（默认值）到lax。
（对于差异，请参见 processContents strict vs lax vs skip for
xsd:any.)
您选择哪条路线取决于您希望对属于 xsd:any 的 Google 元素进行多少验证。第一条路线将提供更严格的验证，但您的下一个问题将是您必须更改 XML 或 XSD 以修复更多错误，例如 g:mpn 没有声明。第二条路线将幸福地忽略此类错误。
我在任何地方都找不到 XSD，但 Google 在这里有提要规范：
https://support.google.com/merchants/answer/7052112

但是，即使使用这个 XSD 来验证您的 XML 仍然会导致如下错误：
[Error] feed.xml:12:14: cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element 'g:brand'.
Google 基础命名空间
要消除与 http://base.google.com/ns/1.0 Google Base namespace extensions 相关的错误，您有两个选择：
将 Google 基础 XSD 导入 Atom XSD:
<xs:import namespace="http://base.google.com/ns/1.0" schemaLocation="base-google.xsd"/>这里的挑战是 (a) 与
http://base.google.com/ns/1.0命名空间关联的 XSD 似乎并不存在于众所周知的官方位置，以及 (b) XSD可能不会被维护。我找到了一个 here。 [如果有人知道更官方或更新的 Google Base XSD，请发表评论，我会更新 link。]松开
xsd:any/@processContents="strict"（默认值）到lax。 （对于差异，请参见 processContents strict vs lax vs skip for xsd:any.)
您选择哪条路线取决于您希望对属于 xsd:any 的 Google 元素进行多少验证。第一条路线将提供更严格的验证，但您的下一个问题将是您必须更改 XML 或 XSD 以修复更多错误，例如 g:mpn 没有声明。第二条路线将幸福地忽略此类错误。
我在任何地方都找不到 XSD，但 Google 在这里有提要规范： https://support.google.com/merchants/answer/7052112
不是XSD你
