我正在尝试使用xmllint来检查我的工作,同时开发一个基本的XSD,即XML Schema架构.但它给了我一个错误
Validation Failed: no DTD found.
我究竟做错了什么？
我的xmllint命令：
xmllint --noout --valid --schema simple.xsd lucas-basic.xml lucas-basic.xml:5: validity error : Validation Failed: no DTD found ! > ^ lucas-basic.xml validates
测试XSD文件：
<?xml version = "1.0" encoding = "UTF-8"?>
<!--Generated by XML Authority. Conforms to w3c http://www.w3.org/2001/XMLSchema-->
<xsd:schema xmlns:xsd = "http://www.w3.org/2001/XMLSchema">
<xsd:element name = "vehicles">
<xsd:complexType>
<xsd:sequence>
<xsd:element name = "nickname" type = "xsd:string" maxOccurs = "unbounded"/>
</xsd:sequence>
</xsd:complexType>
</xsd:element>
测试XML文件：
<?xml version="1.0"?>
<vehicles
xmlns:xsi = "http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation = "http://lucas.ucs.ed.ac.uk/xml-schema/xmlns/simple.xsd"
>
<nickname>Bog Hopper</nickname>
<nickname>Wee Beastie</nickname>
<nickname>Count Zero</nickname>
</vehicles>
xsi：noNamespaceSchemaLocation上的URL确实返回上面的XSD.此外,我下载了xsd文件并将其作为额外措施放入当前目录,但这似乎没有改变任何东西.
– 无效是针对DTD,而不是XSD.

xmllint --noout --schema http://lucas.ucs.ed.ac.uk/xml-schema/xmlns/simple.xsd lucas-basic.xml
