如何为两级分层数据创建平面文件XSD架构？
我是BizTalk中的新手，我必须从CSV文件创建XSD架构：
如您所见，它包括标题和订单。每个订单都有自己的订单标题 - 包含商店名称和填充Period字段的行，但是空Quantity，Price，Cost和Currency领域。除Period外，每个订单的位置都很少，这些位置已填满所有字段。每个订单头都有ItemNumber = 0.如何在这种情况下创建正确的平面文件架构？
OrderDate;OrderNumber;ItemNumber;DESCRIPTION_LONG;Quantity;Price;Cost;Period;Currency
30-04-17;9;0;Shop: McDonalds;;;;2017-04;
30-04-17;9;1;Double burger;2;5,99;11,98;;USD
30-04-17;9;2;Coca-Cola;2;2,19;4,38;;USD
30-04-17;10;0;Shop: Hunting and fishing;;;;2017-04;
30-04-17;10;1;Fishing rod;2;10,90;21,80;;USD
30-04-17;10;2;Bait;5;1,00;5,00;;USD
30-04-17;10;3;Hunting gun;1;999,00;999,00;;USD

我认为最好的选择是将平面文件解析为XML，而不是试图“强制”最终结构，正如Pieter在回答之前所说。像这样：

使用类似于此的平面架构：
def custom_getter(my_dict, my_key):
# If the key is in the dictionary, we return its value
if my_key in my_dict:
return my_dict[my_key]
# If the key is NOT in the dictionary, we return an empty string
return ''
output_file = csv.writer(open('transactions000000000029.csv', 'wb+'))
output_file.writerow(['blockNumber','blockHash','hash','from','to','gas','gasUsed','gasPrice','input','logs','nonce','value','timestamp'])
for line in inpt:
resource = json.loads(line)
output_file.writerow(
[custom_getter(resource,'blockNumber'),
custom_getter(resource,'blockHash'),
custom_getter(resource,'hash'),
custom_getter(resource,'from'),
custom_getter(resource,'to'),
custom_getter(resource,'gas'),
custom_getter(resource,'gasUsed'),
custom_getter(resource,'gasPrice'),
custom_getter(resource,'input'),
custom_getter(resource,'logs'),
custom_getter(resource,'nonce'),
custom_getter(resource,'value'),
custom_getter(resource,'timestamp')]
)
然后使用地图获取最终结果，使用NumPy inspects
等分组机制答案 1 :(得分：1)
您可以使用标记标识符来执行此操作（请参阅https://blogs.msdn.microsoft.com/biztalknotes/2013/02/05/flat-file-schema-creation-with-tag-identifiers-in-the-input-flat-file-repeating-in-a-random-fashion/获取示例），但我不能100％确定这可以正常工作，因为标识符（ItemNumber = 0）不在线的开头。我的经验告诉我，平面文件反汇编程序探测在这些情况下成功有限。
在这种情况下，我对人们的一般建议是不要在平面文件架构中尝试“强制”结构，因为很明显你的平面文件结构没有它。我看到的是每一行都有相同的结构/格式。它只是在功能上不同。
从这个角度来看，我会选择一个与你的CSV文件结构相匹配的Flat File模式（一种记录以逗号分隔的字段和一行换行作为行分隔符），然后从那里映射到一个模式在功能上更有意义。
答案 2 :(得分：1)
我的解决方案是，
-
创建用于解析平面文件的源架构。
-
为分组结果创建目标架构
-
为您的源架构创建一个地图组。
- 将此内联XSLT脚本添加到地图
- 测试您的地图并获得此输出。
第一个脚本functoid
<xsl:key name="groups" match="Order" use="OrderNumber"/>
对于第二个脚本functoid
<xsl:for-each select="Order[generate-id(.)=generate-id(key('groups',OrderNumber))]">
<xsl:sort select="OrderNumber" order="ascending"/>
<xsl:choose>
<xsl:when test="OrderDate != 'OrderDate'">
<Order>
<OrderDate><xsl:value-of select="OrderDate/text()" /></OrderDate>
<OrderNumber><xsl:value-of select="OrderNumber/text()" /></OrderNumber>
<Description><xsl:value-of select="Description/text()" /></Description>
<Period><xsl:value-of select="Period/text()" /></Period>
<Items>
<xsl:for-each select="key('groups',OrderNumber)">
<xsl:choose>
<xsl:when test="ItemNumber > '0'">
<Item>
<ItemNumber><xsl:value-of select="ItemNumber" /></ItemNumber>
<Quantity><xsl:value-of select="Quantity" /></Quantity>
<Price><xsl:value-of select="Price" /></Price>
<Cost><xsl:value-of select="Cost" /></Cost>
<Currency><xsl:value-of select="Currency" /></Currency>
</Item>
</xsl:when>
</xsl:choose>
</xsl:for-each>
</Items>
</Order>
</xsl:when>
</xsl:choose>
</xsl:for-each>
<ns0:Orders xmlns:ns0="http://BizTalkServerTestProject.FlatFileSchema6">
