[英]BizTalk - Build XSD for flat file with words delimiter at start and end of records
I am trying to build an XSD file based on the following text file (flat file).我正在尝试基于以下文本文件(平面文件)构建 XSD 文件。 I am using the flat file schema wizard but can't achieve what I want.
我正在使用平面文件模式向导,但无法实现我想要的。
:BEGIN
Key1 Value1
Key2 Value2
:END
:BEGIN
Key1 Value1
Key2 Value2
Key3 Value3
:END
:BEGIN
:END
The XSD would be something like : XSD 将类似于:
Record (Delimited by :BEGIN and :END)
|_Association (Delimited by \n)
|_Key (Delimited by space, first occurence)
|_Value (second occurence)
I would like my txt file to be transformed as an instance of the xsd file in xml.我希望我的 txt 文件被转换为 xml 中 xsd 文件的一个实例。 The result would be something like :
结果将是这样的:
<Record>
<Association>
<Key>Key1</Key>
<Value>Value1</Value>
</Association>
<Association>
<Key>Key2</Key>
<Value>Value2</Value>
</Association>
</Record>
<Record>
<Association>
<Key>Key1</Key>
<Value>Value1</Value>
</Association>
<Association>
<Key>Key2</Key>
<Value>Value2</Value>
</Association>
<Association>
<Key>Key3</Key>
<Value>Value3</Value>
</Association>
</Record>
There is only 2 records because last :BEGIN:END block is empty.只有 2 条记录,因为最后一个 :BEGIN:END 块是空的。
My main issue is that I can't find out how to delimit my records by :START and :END tags.我的主要问题是我无法找到如何通过 :START 和 :END 标记分隔我的记录。 Is that even possible ?
这甚至可能吗?
Yes, it is possible to do, but not with the Wizard.是的,可以这样做,但不能使用向导。 It is a matter of manually building it up and testing the structure as you add definitions.
这是在添加定义时手动构建和测试结构的问题。
It is a matter of using Tag Identifiers for the :BEGIN and :END as well using a Sequence Group to say that these re-occur.使用 :BEGIN 和 :END 的标签标识符以及使用序列组来说明这些重新出现是一个问题。
Additionally at the <Schema>
level set Parser Optimization to Complexity.此外,在
<Schema>
级别将 Parser Optimization 设置为 Complexity。
Depending on what defines the end of your line, you may need to adjust the 0x0A 0x0D (Carriage Return & Line Feed) to what your file actually contains.根据定义行尾的内容,您可能需要将 0x0A 0x0D(回车和换行)调整为文件实际包含的内容。 Also if the last line does not finish with a CR/LF then change it from being Postfix (after) to Infix (between).
此外,如果最后一行没有以 CR/LF 结束,则将其从后缀(后)更改为中缀(之间)。
