问题
I'm using two different xsd schema files in one project.
First one is input.xsd
. This file uses targetNamespace
:
<?xml version="1.0" encoding="UTF-8"?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:w3s="https://www.w3schools.com"
targetNamespace="https://www.w3schools.com">
<xsd:element name="Mobiles">
<xsd:complexType>
<xsd:sequence>
<xsd:element name="Mobile" type="w3s:Mobile" maxOccurs="unbounded"/>
</xsd:sequence>
</xsd:complexType>
</xsd:element>
<xsd:complexType name="Mobile">
<xsd:sequence>
<xsd:element name="Model" type="xsd:string"/>
<xsd:element name="OS">
<xsd:simpleType>
<xsd:restriction base="xsd:string">
<xsd:enumeration value="Android"/>
</xsd:restriction>
</xsd:simpleType>
</xsd:element>
<xsd:element name="Origin" type="xsd:string"/>
<xsd:element name="Material" type="xsd:string"/>
<xsd:element name="Samsung" type="w3s:Samsung"/>
</xsd:sequence>
</xsd:complexType>
<xsd:complexType name="Samsung" mixed="true">
<xsd:sequence>
<xsd:element name="Wlan">
<xsd:simpleType>
<xsd:restriction base="xsd:string">
<xsd:enumeration value="802.11"/>
</xsd:restriction>
</xsd:simpleType>
</xsd:element>
<xsd:element name="CardSlot" type="xsd:string"/>
<xsd:element name="RadioAvailability" type="xsd:boolean" default="true"/>
<xsd:element name="BluetoothAvailability" type="xsd:boolean" default="false"/>
</xsd:sequence>
</xsd:complexType>
</xsd:schema>
Another is input_noTargetNamespace.xsd
. This file doesn't have targetNamespace
:
<?xml version="1.0" encoding="UTF-8"?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<xsd:element name="Mobiles">
<xsd:complexType>
<xsd:sequence>
<xsd:element name="Mobile" type="Mobile" maxOccurs="unbounded"/>
</xsd:sequence>
</xsd:complexType>
</xsd:element>
<xsd:complexType name="Mobile">
<xsd:sequence>
<xsd:element name="Model" type="xsd:string"/>
<xsd:element name="OS">
<xsd:simpleType>
<xsd:restriction base="xsd:string">
<xsd:enumeration value="Android"/>
</xsd:restriction>
</xsd:simpleType>
</xsd:element>
<xsd:element name="Origin" type="xsd:string"/>
<xsd:element name="Material" type="xsd:string"/>
<xsd:element name="Samsung" type="Samsung"/>
</xsd:sequence>
</xsd:complexType>
<xsd:complexType name="Samsung" mixed="true">
<xsd:sequence>
<xsd:element name="Wlan">
<xsd:simpleType>
<xsd:restriction base="xsd:string">
<xsd:enumeration value="802.11"/>
</xsd:restriction>
</xsd:simpleType>
</xsd:element>
<xsd:element name="CardSlot" type="xsd:string"/>
<xsd:element name="RadioAvailability" type="xsd:boolean" default="true"/>
<xsd:element name="BluetoothAvailability" type="xsd:boolean" default="false"/>
</xsd:sequence>
</xsd:complexType>
</xsd:schema>
XML file looks like:
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<p7:Mobiles xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:p7="https://www.w3schools.com"
xsi:schemaLocation="https://www.w3schools.com input.xsd" >
<Mobile>
<Model>G975F</Model>
<OS>Android</OS>
<Origin>USA</Origin>
<Material>Plastic</Material>
<Samsung>
<Wlan>802.11</Wlan>
<CardSlot>MicroSD</CardSlot>
<RadioAvailability>true</RadioAvailability>
<BluetoothAvailability>true</BluetoothAvailability>
</Samsung>
</Mobile>
<Mobile>
<Model>G986</Model>
<OS>Android</OS>
<Origin>USA-Israel</Origin>
<Material>Silicon-Plastic</Material>
<Samsung>
<Wlan>802.11</Wlan>
<CardSlot>MicroSD</CardSlot>
<RadioAvailability>true</RadioAvailability>
<BluetoothAvailability>false</BluetoothAvailability>
</Samsung>
</Mobile>
<Mobile>
<Model>G770F</Model>
<OS>Android</OS>
<Origin>Israel</Origin>
<Material>Silicon-Plastic</Material>
<Samsung>
<Wlan>802.11</Wlan>
<CardSlot>MicroSD</CardSlot>
<RadioAvailability>true</RadioAvailability>
<BluetoothAvailability>false</BluetoothAvailability>
</Samsung>
</Mobile>
</p7:Mobiles>
If I use these separate xsd schema files in one project, SonarQube shows the error:
Error resolving component 'w3s:Mobile'. It was detected that 'w3s:Mobile' is in namespace 'https://www.w3schools.com', but components from this namespace are not referenceable from schema document. If this is the incorrect namespace, perhaps the prefix of 'w3s:Mobile' needs to be changed. If this is the correct namespace, then an appropriate 'import' tag should be added to 'input_noTargetNamespace.xsd'.
Does anyone know why it happens? I can provide any other information if needed. Thanks in advance.
回答1:
The issue was solved with the following files and content:
input.xml
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<Mobiles
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="input.xsd">
<Mobile>
<Model>G975F</Model>
<OS>Android</OS>
<Origin>USA</Origin>
<Material>Plastic</Material>
<Samsung>
<Wlan>802.11</Wlan>
<CardSlot>MicroSD</CardSlot>
<RadioAvailability>true</RadioAvailability>
<BluetoothAvailability>true</BluetoothAvailability>
</Samsung>
</Mobile>
<Mobile>
<Model>G986</Model>
<OS>Android</OS>
<Origin>USA-Israel</Origin>
<Material>Silicon-Plastic</Material>
<Samsung>
<Wlan>802.11</Wlan>
<CardSlot>MicroSD</CardSlot>
<RadioAvailability>true</RadioAvailability>
<BluetoothAvailability>false</BluetoothAvailability>
</Samsung>
</Mobile>
<Mobile>
<Model>G770F</Model>
<OS>Android</OS>
<Origin>Israel</Origin>
<Material>Silicon-Plastic</Material>
<Samsung>
<Wlan>802.11</Wlan>
<CardSlot>MicroSD</CardSlot>
<RadioAvailability>true</RadioAvailability>
<BluetoothAvailability>false</BluetoothAvailability>
</Samsung>
</Mobile>
</Mobiles>
To be more specific: I've modified xml to realize correct linking an XSD to an XML document without namespaces:
<Mobiles
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="input.xsd">
Hence input.xsd looks like:
<?xml version="1.0" encoding="UTF-8"?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<xsd:element name="Mobiles">
<xsd:complexType>
<xsd:sequence>
<xsd:element name="Mobile" type="Mobile" maxOccurs="unbounded"/>
</xsd:sequence>
</xsd:complexType>
</xsd:element>
<xsd:complexType name="Mobile">
<xsd:sequence>
<xsd:element name="Model" type="xsd:string"/>
<xsd:element name="OS">
<xsd:simpleType>
<xsd:restriction base="xsd:string">
<xsd:enumeration value="Android"/>
</xsd:restriction>
</xsd:simpleType>
</xsd:element>
<xsd:element name="Origin" type="xsd:string"/>
<xsd:element name="Material" type="xsd:string"/>
<xsd:element name="Samsung" type="Samsung"/>
</xsd:sequence>
</xsd:complexType>
<xsd:complexType name="Samsung" mixed="true">
<xsd:sequence>
<xsd:element name="Wlan">
<xsd:simpleType>
<xsd:restriction base="xsd:string">
<xsd:enumeration value="802.11"/>
</xsd:restriction>
</xsd:simpleType>
</xsd:element>
<xsd:element name="CardSlot" type="xsd:string"/>
<xsd:element name="RadioAvailability" type="xsd:boolean" default="true"/>
<xsd:element name="BluetoothAvailability" type="xsd:boolean" default="false"/>
</xsd:sequence>
</xsd:complexType>
</xsd:schema>
without using input_noTargetNamespace.xsd
because of redundancy.
And for xsd file I've changed:
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:w3s="https://www.w3schools.com"
targetNamespace="https://www.w3schools.com">
simply to
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema">
