Use two xsd schemas in visual studio 2012

问题

I've got a webservice that generates some XML.

<Town>
<Countrycode>gb</Countrycode>
<CountryName>United Kingdom</CountryName>
<CleanedAccentCity>Seamill</CleanedAccentCity>
<RegionName>North Ayrshire</RegionName>
<Population>0</Population>
<Distance>0.0497417145329766</Distance>
</Town>

This I added to my Visual Studio 2012 project by Add New Item... XML to schema.

That works great I wind up with an xsd file in my project then in code I can write:

 Public Property returnedXML As XElement

  arr = client.DownloadString("http://host/myservice.asmx/GetTopTownsByLatLon?Latitude=" & p.latitude & "&Longitude=" & p.longitude )

     returnedXML = XElement.Parse(arr)

     firstChild = returnedXML.Descendants().First

     City = firstChild...<City>.Value
      etc..

And when I type the .. after firstChild I get intellisense that shows me the attributes in the XML.

Now what I need to do is get another different webservice to give me some other data. So I do the same process, and get my XSD files saved into the project. But, guess what, the intellisense no longer works.

Clearly I need to identify which XSD file needs to be read for the intelisense. Where do I set that?

Here are the two XSD files:

<?xml version="1.0" encoding="utf-8"?>
<xs:schema attributeFormDefault="unqualified" elementFormDefault="qualified" xmlns:xs="http://www.w3.org/2001/XMLSchema">
  <xs:element name="Towns">
    <xs:complexType>
      <xs:sequence>
        <xs:element maxOccurs="unbounded" name="Town">
          <xs:complexType>
            <xs:sequence>
              <xs:element name="name" type="xs:string" />
              <xs:element name="url" type="xs:string" />
              <xs:element name="Distance" type="xs:unsignedByte" />
            </xs:sequence>
          </xs:complexType>
        </xs:element>
      </xs:sequence>
    </xs:complexType>
  </xs:element>
</xs:schema>

and

<?xml version="1.0" encoding="utf-8"?>
<xs:schema attributeFormDefault="unqualified" elementFormDefault="qualified" xmlns:xs="http://www.w3.org/2001/XMLSchema">
  <xs:element name="Towns">
    <xs:complexType>
      <xs:sequence>
        <xs:element maxOccurs="unbounded" name="Town">
          <xs:complexType>
            <xs:sequence>
              <xs:element name="Countrycode" type="xs:string" />
              <xs:element name="CountryName" type="xs:string" />
              <xs:element name="CleanedAccentCity" type="xs:string" />
              <xs:element name="RegionName" type="xs:string" />
              <xs:element name="Population" type="xs:unsignedByte" />
              <xs:element name="Distance" type="xs:decimal" />
            </xs:sequence>
          </xs:complexType>
        </xs:element>
      </xs:sequence>
    </xs:complexType>
  </xs:element>
</xs:schema>

Thanks

回答1:

If there are conflicts between these schemes definitions (like duplicated element definitions etc.), the source is not compiled and intellisense not work.

Can you share both XSD files?

EDIT:

Both XSD has a duplicate elements (<Towns>, <Town> and <Distance>) and no namespace definitions, so there is no way to difference between theirs. In order to works properly you have two ways:

First way: Change these name elements in only one of your XSD, for example <TownsA>, <TownA>, <DistanceA>:

<?xml version="1.0" encoding="utf-8"?>
<xs:schema attributeFormDefault="unqualified" elementFormDefault="qualified"    xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:element name="TownsA">
<xs:complexType>
  <xs:sequence>
    <xs:element maxOccurs="unbounded" name="TownA">
      <xs:complexType>
        <xs:sequence>
          <xs:element name="name" type="xs:string" />
          <xs:element name="url" type="xs:string" />
          <xs:element name="DistanceA" type="xs:unsignedByte" />
        </xs:sequence>
      </xs:complexType>
    </xs:element>
  </xs:sequence>
</xs:complexType>

And keep the second untouched:

<?xml version="1.0" encoding="utf-8"?>
<xs:schema attributeFormDefault="unqualified" elementFormDefault="qualified" xmlns:xs="http://www.w3.org/2001/XMLSchema">
  <xs:element name="Towns">
    <xs:complexType>
      <xs:sequence>
        <xs:element maxOccurs="unbounded" name="Town">
          <xs:complexType>
            <xs:sequence>
              <xs:element name="Countrycode" type="xs:string" />
              <xs:element name="CountryName" type="xs:string" />
              <xs:element name="CleanedAccentCity" type="xs:string" />
              <xs:element name="RegionName" type="xs:string" />
              <xs:element name="Population" type="xs:unsignedByte" />
              <xs:element name="Distance" type="xs:decimal" />
            </xs:sequence>
          </xs:complexType>
        </xs:element>
      </xs:sequence>
    </xs:complexType>
  </xs:element>
</xs:schema>

Second way: Add a different targetNamespaceNamespaces in your schemas in <xs:schema>:

First XSD:

<xs:schema 
       attributeFormDefault="unqualified" 
       elementFormDefault="qualified" 
       targetNamespace="http://mynamespace.org/1"
       xmlns:xs="http://www.w3.org/2001/XMLSchema">

Second XSD:

<xs:schema 
       attributeFormDefault="unqualified" 
       elementFormDefault="qualified" 
       targetNamespace="http://mynamespace.org/2"
       xmlns:xs="http://www.w3.org/2001/XMLSchema">
