错误“元素不能包含空格.内容模型为空."吝啬的? [英] What does the error "The element cannot contain white space. Content model is empty." mean?
问题描述
我正在为一个简单的 xml 组合一个 xml 模式(有关 xml 和模式,请参见下文).但是我不断收到有关节节点的以下错误:元素不能包含空格.内容模型为空.".浏览网络我找不到任何关于它意味着什么的简明解释,所以我可以修复它.有人可以帮忙吗?
I'm putting together an xml schema for a simple xml (see bellow for both xml and schema). But I keep getting the following error with regards to the section node: "The element cannot contain white space. Content model is empty." . Browsing the net I could not find any concise explanation as to what it means so I can fix it. Can anyone help?
感谢大家为架构提供帮助.我认为简要描述什么是内容模型以及为什么此处为空会有所帮助.
thanks for all for offering help with the schema. I think it would help to have a concise description of what content model is and why it is empty here.
XML:
<config>
<section name="facets">
<facet type="format" label="Format" max="4"/>
<facet type="language" max="4"/>
<facet type="pubdate" max="6" submax="8"/>
<facet type="ice_topic" label="Fiction: Topic"/>
</section>
</config>
架构:
<?xml version="1.0" encoding="utf-8"?>

<xs:element name="config">

推荐答案
facet 的 label 属性设置为 xs:ID 并且不允许空格.您可能想改用 xs:string.
The label attribute of facet is set to xs:ID and this doesn't allow spaces. You might want to use xs:string instead.
