问题描述
我在流感期间一直在研究这个高级"模式,但我不明白为什么它一直告诉我找不到网站".我重新阅读了这一章,甚至创建了一个副本进行试验(以前有效),但我不明白.我正在尝试导入和组合模式,但我不确定如何使其正常工作......以下是错误:
I have been working on this "advanced" schema for days with the flu and I cannot figure out why it keeps telling me that "sites" is not found. I re-read the chapter and even created a copy to experiment with (which worked before) and I do not understand. I am trying to import and combine schemas and I am not sure how to get it to work properly... Here are the errors:
Ln 16 Col 84 - cvc-elt.1:找不到元素的声明站点".1 错误 [Xerces-J 2.9.1] 验证 XML 模式sites.xsd"... Ln 32 Col 49 - src-resolve.4.1:解析组件站点"时出错.检测到 'sites' 没有命名空间,但组件没有目标命名空间不可从架构文档中引用.
如果 'sites' 打算有一个命名空间,也许前缀需要提供.如果 'sites' 没有命名空间,那么应该添加没有命名空间"属性的导入"
If 'sites' is intended to have a namespace, perhaps a prefix needs to be provided. If it is intended that 'sites' has no namespace, then an 'import' without a "namespace" attribute should be added
这是架构:
<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:cc="http://example.com/weekendfunsnacks/sites/ns"

推荐答案
你的 XSD 有一个 targetNamespace
,所以你的 ref="sites"
必须引用那个命名空间.
Your XSD has a targetNamespace
, so your ref="sites"
has to reference that namespace.
定义一个命名空间前缀,比如w:
,与目标命名空间相同,然后在引用中使用:ref=w:sites"
:
Define a namespace prefix, say w:
, to be the same as the target namespace, and then use it in the reference: ref="w:sites"
:
<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
targetNamespace="http://example.com/weekendfunsnacks/sites"
xmlns:w="http://example.com/weekendfunsnacks/sites"
elementFormDefault="qualified" attributeFormDefault="unqualified">
<xs:import namespace="http://www.sitemaps.org/schemas/sitemap/0.9"
schemaLocation="http://www.sitemaps.org/schemas/sitemap/0.9/sitemap.xsd" />
<xs:element name="sites">
