c# - Zillow 的 SearchResults.xsd 和 Visual Studio 的 XSD 命令

Question

我尝试在 zillow“SearchResults.xsd”上​​运行 Visual Studio 的 XSD.EXE 实用程序来生成 c# 或 vb.net 类，但我没有运气，正在寻求帮助。我不断收到错误(见下文)。这是我从 http://www.zillow.com/howto/api/GetDeepSearchResults.htm 下载的原始文件:

                </xsd:element>

            </xsd:sequence>
        </xsd:complexType>
    </xsd:element>

</xsd:schema>

以下是我在 Visual Studio 2010 中尝试 XSD.EXE 时不断遇到的错误:

Warning: Schema could not be validated. Class generation may fail or may produce
 incorrect results.

Error: Error generating classes for schema 'SearchResults'.
  - The datatype 'http://www.zillow.com/static/xsd/ZillowTypes.xsd:Message' is missing.

看起来一切都在 ZillowTypes.xsd 中定义，所以我很困惑。

Answer 1

设置有几个问题。从 XSD 文件的位置开始，它应该位于 http://www.zillow.com/static/xsd/SearchResults.xsd。

上面的 XSD 引用了另一个 xsd，它使用带有相对 uri /vstatic/4/static/xsd/ZillowTypes.xsd 的导入，解析为 http://www.zillow.com/vstatic/4/static/xsd/ZillowTypes.xsd - 但此 URL 不可取消引用 (404)!!

如果改为尝试 http://www.zillow.com/static/xsd/ZillowTypes.xsd然后您找到了拼图的第 2 部分，即 ZillowTypes.xsd。

由于这些错误，您需要将这两个 XSD 文件下载到本地计算机以修复它们。

首先下载SearchResults.xsd，然后下载ZillowTypes.xsd；将它们放在同一个文件夹中。

通过更改以下行来编辑 SearchResults.xsd:

<xsd:import namespace="http://www.zillow.com/static/xsd/ZillowTypes.xsd" schemaLocation="/vstatic/4/static/xsd/ZillowTypes.xsd" /> 

到:

<xsd:import namespace="http://www.zillow.com/static/xsd/ZillowTypes.xsd" schemaLocation="ZillowTypes.xsd"  />

然后你遇到了另一个问题。 ZillowTypes.xsd 包含无效的元素声明!所以编辑下面的声明:

<xsd:complexType name="investmentBuyingBlock">
    <xsd:sequence>
        <xsd:element name="buying" minOccurs="0" maxOccurs="unbounded">
            <xsd:sequence>
                <xsd:element name="year" type="xsd:integer"/>
                <xsd:element name="rentalIncome" type="xsd:integer"/>
                <xsd:element name="otherIncome" type="xsd:integer"/>
                <xsd:element name="mortgagePayment" type="xsd:integer"/>
                <xsd:element name="principal" type="xsd:integer"/>
                <xsd:element name="interest" type="xsd:integer"/>
                <xsd:element name="hoaFees" type="xsd:integer"/>
                <xsd:element name="propertyTaxes" type="xsd:integer"/>
                <xsd:element name="utilities" type="xsd:integer"/>
                <xsd:element name="renovations" type="xsd:integer"/>
                <xsd:element name="maintainCosts" type="xsd:integer"/>
                <xsd:element name="homeOwnerInsurance" type="xsd:integer"/>
                <xsd:element name="managementFees" type="xsd:integer"/>
                <xsd:element name="advertisingCosts" type="xsd:integer"/>
                <xsd:element name="otherExpenses" type="xsd:integer"/>
                <xsd:element name="totalExpenses" type="xsd:integer"/>
                <xsd:element name="opportunityCostInitial" type="xsd:integer"/>
                <xsd:element name="opportunityCostYearly" type="xsd:integer"/>
                <xsd:element name="depreciationBuilding" type="xsd:integer"/>
                <xsd:element name="depreciationrenovation" type="xsd:integer"/>
                <xsd:element name="totalBenefit" type="xsd:integer"/>
                <xsd:element name="totalProfitLoss" type="xsd:integer"/>
            </xsd:sequence>
        </xsd:element>
    </xsd:sequence>
</xsd:complexType>

                    <xsd:element name="totalProfitLoss" type="xsd:integer"/>
                </xsd:sequence>
            </xsd:complexType>
        </xsd:element>
    </xsd:sequence>
</xsd:complexType>

通过替换重新运行 XSD 命令行

搜索结果.xml

与

SearchResults.xsd ZillowTypes.xsd

它应该可以工作(至少 XSD 现在有效)。
