BizTalk-在记录的开头和结尾使用单词定界符为平面文件构建XSD

问题描述

我正在尝试基于以下文本文件（平面文件）构建XSD文件。我正在使用平面文件架构向导，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

XSD类似于：

Record (Delimited by :BEGIN and :END)
|_Association (Delimited by \n)
  |_Key (Delimited by space,first occurence)
  |_Value (second occurence)

我希望将txt文件转换为xml中xsd文件的实例。结果将是：

<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>

只有2条记录，因为最后一个：BEGIN：END块为空。

我的主要问题是我找不到如何通过：START和：END标记来分隔记录的方法。那有可能吗？

解决方法

是的，可以这样做，但不能使用向导。添加定义时，只需手动构建它并测试结构即可。

使用标记标识符来表示：BEGIN和：END以及使用序列组来表示它们是重复出现的。

此外，在<Schema>级别上，将“解析器优化”设置为“复杂性”。

取决于定义行尾的内容，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。另外，如果最后一行没有以CR / LF结尾，则将其从Postfix（之后）更改为Infix（之间）。
