使用 xmllint 针对远程文件验证 xml

Question

我正在尝试根据在线模式验证一些 xml 数据。

$ xmllint --schema https://raw.githubusercontent.com/IATI/IATI-Schemas/version-2.01/iati-activities-schema.xsd --noout iati-data/*.xml

Returns:

warning: failed to load external entity "https://raw.githubusercontent.com/IATI/IATI-Schemas/version-2.01/iati-activities-schema.xsd"
Schemas parser error : Failed to locate the main schema resource at 'https://raw.githubusercontent.com/IATI/IATI-Schemas/version-2.01/iati-activities-schema.xsd'.
WXS schema https://raw.githubusercontent.com/IATI/IATI-Schemas/version-2.01/iati-activities-schema.xsd failed to compile

然而，xsd确实存在：

curl https://raw.githubusercontent.com/IATI/IATI-Schemas/version-2.01/iati-activities-schema.xsd

Returns

<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" version="2.01">

  <xsd:annotation>
    <xsd:documentation xml:lang="en">
      International Aid Transparency Initiative: Activity-Information Schema

      Release 2.01, 2014-10-21

etc...

不确定我做错了什么...

不幸的是 that XSD 被写入使用支持 XSD 的相对路径。评论中甚至有一条说明：

  NOTE: the xml.xsd and iati-common.xsd schemas must be in the
  same directory as this one.

如果您无法更改 XSD 以引用包含和导入的 XSD 的完整、绝对 URL，解决方法是下载主要 XSD 及其依赖项并访问本地 main XSD。另一种解决方法是使用 XML Catalog 以绝对 URL 术语重新映射从属 XSD 的位置。
