如何从左到右解析可选字段，并将BizTalk平面文件解析器设置为复杂？

Question

我正在为BizTalk 2013中的平面文件反汇编开发一个模式。但是，我对模式有一个很大的问题，因为解析结果是垃圾。 我正在解析的平面文件类型如下所示：

HEADER:opt1:opt2:opt3+opt4:opt5+opt6+op7:opt8:opt9'
TAG1:opt1:opt2:opt3+opt4:opt5:opt6+op7:opt8:opt9'
TAG2:opt1:opt2:opt3+opt4:opt5:opt6+op7:opt8:opt9'
TAG3:opt1:opt2:opt3+opt4++opt6+op7:opt8:opt9'
TAG4:opt1:opt2:opt3+opt4:opt5'

平面文件有三个层次结构部分：

顶级：细分，由'字符分隔（不是换行符，只是为了更好的可读性而添加）

中级：字段，由+字符分隔。可以直接包含一个值或一组值（参见底层）

底层：属性，由：字符

分隔

由于 TAG？ -Segments是部分可选的并且可能以多个顺序发生，我使用parser_optimization =“complexity”选项以及lookahead_depth =“0”并使用 TAG ？ -Name来标识段类型，我用来解析所有内容。 所有分隔符都是child_order =“infix”，除了段是child_order =“postfix”。

某些细分，字段和属性是必需的，大部分都不是。但是，始终需要第一个字段及其属性（标记名称，...）。 段的分离和识别工作正常，字段也正常工作。但是，当我有包含一组可选属性的可选字段时，架构无法正确解析。 例： 语法：

TAGX:opt1:opt2:opt3+a1:a2:a3:a4:a5:a6'

所有 a？属性都是可选的

在解析像这样的片段时，属性值被放入正确的XML字段中：

TAGX:1:2:3+:1:2:::'

但是，由于平面文件规范允许省略可选字段，因此消息也可能如下所示：

TAGX:1:2:3+:1:2'

在这种情况下，值不会像它们应该放在第二个和第三个XML字段中，而是放在第三个和第四个字段中。根据我在段中包含的符号数量，也可以填充第一个和第六个，第二个和第四个XML字段。

我需要平面文件解析器从左到右填充这些字段，而不是现在使用的混乱方式。但是，切换到parser_optimization =“speed”不是一个选项，因为架构的其余部分太复杂（除非有办法在本地执行此操作）。

这些是用于解析此类字段的XSD架构的一部分（仅提取的部分，因为架构非常大）

您的特定提取缺少SEG_HEAD_REF1_TYPE的定义，还有其他问题，当我尝试生成实例时，我得到“自定义组件调用失败”。但是，我根据您的平面文件模拟样本创建了一个平面文件架构，该样本可以正确解析以下示例。 （注意：我不得不从架构中删除缩进，否则它太大而无法发布）。
