xsd:boolean 元素类型接受“true";但不是“真".我怎样才能让它接受它? [英] xsd:boolean element type accept "true" but not "True". How can I make it accept it?
问题描述
我正在使用 xmllint --schema 选项来验证我的 XML,看起来像这样
<XML><主动>真</主动></XML>
在我的架构文件中,我有以下描述 Active 元素的行.
<xsd:element name="Active" type="xs:boolean"/>
当我运行 xmllint 时,我收到错误消息,上面写着
<块引用>/tmp/schema_validation.xml:73: 元素活动:模式有效性错误:元素活动":真"不是原子类型的有效值'xs:boolean'.
当我将 XML 更改为
<Active>true</Active>
然后错误信息消失.
所以,看起来 xsd:boolean 对 xmllint 来说都是小写的真/假",但不是真/假".我的问题是,我怎样才能让 xmllint 接受 xsd:boolean 类型的真"?或者我可以使用不同的工具来验证这个 XML?在这一点上,更改 XML 或架构不是我的选择.
谢谢!
你不能.
根据 XML Schema 规范,布尔值是 true
或 false
.True
无效:
如果您使用的工具确实根据 XML Schema 标准进行验证,那么您无法说服它接受 True 作为布尔值.
I am using xmllint --schema option to validate my XML that looks like this
<XML>
<Active>True</Active>
</XML>
In my schema file, I have following line that describes Active element.
<xsd:element name="Active" type="xs:boolean" />
When I run xmllint, I get error messages that says
/tmp/schema_validation.xml:73: element Active: Schemas validity error : Element 'Active': 'True' is not a valid value of the atomic type 'xs:boolean'.
When I change the XML to
<Active>true</Active>
Then the error message disappears.
So, it looks like xsd:boolean means it's all lowercase "true/false" but not "True/False" to xmllint.. My question is, how can I make xmllint to accept "True" for xsd:boolean type? Or is there different tools that I can use that will validate this XML? Changing the XML or schema is not my option at this point.
Thanks!
You cannot.
According to the XML Schema specification, a boolean is true
or false
. True
is not valid:
3.2.2.1 Lexical representation An instance of a datatype that is defined as ·boolean· can have the following legal literals {true, false, 1, 0}. 3.2.2.2 Canonical representation The canonical representation for boolean is the set of literals {true, false}.
If the tool you are using truly validates against the XML Schema standard, then you cannot convince it to accept True for a boolean.
