遍历BizTalk中的脚本功能 [英] Looping over a scripting functoid in BizTalk

问题描述

我有一个字符串值列表，例如'123','456','789'等.这个列表可能很长，只有几千个项目.因此，我必须将其分成最大块. 750个项目.
一个想法是编写一个自己的functoid，将其分解并返回一个可循环的列表.也许它会更容易一些，我可以直接在脚本functoid中完成它.但是我收到消息

I've got a list of string values like '123','456','789' and so on. This list can be very long with a few thousand items. So I have to split it in blocks of max. 750 items.
One idea is to write an own functoid which split in and returns a loopable list. Maybe it is a little bit easier and i could do it direcly in a scripting functoid. But I get the message

`error btm1090: The "Looping" functoid has place holders. Replace these with appropriate links or constants.`

所以我认为这是不可能的.是否有可能在脚本功能中执行此操作?我是否需要自己的功能?

So I don't think that this is possible. Is there a possibility to do it in a Scripting functoid or do I need my own functoid?

一方面，我需要分割后的值来创建多条结果行(通过循环)，但每一行中的值本身也是如此.

I need the splitted values on the one hand to create multiple results lines (by looping) but also the value itself in each line.

谢谢.

推荐答案

我将使用其他方法.与其尝试在Xsl中不做受限循环(这很困难)，不如在C#函数中生成所有Xml，这非常容易.

I would use a different approach. Instead of trying to do a restricted loop in Xsl, which is hard, I would generate all the Xml in a C# function, which is pretty easy.

第1步，编写一些C#来创建所需的Xml输出:

Step 1, write some C# that create the Xml output you need:

<LineValue>'1','2','3',...,'749','750'</LineValue>
<LineValue>'751','752','753',...,'1499','1500'</LineValue>
<LineValue>'1501','1502','1503',...,'2249','2250'</LineValue>

通常首选外部程序集，但内联也可以.但是，真的没关系，只需将此Xml作为字符串返回即可.

An External Assembly is generally preferred but inline works just as well. But, it really doesn't matter, just return this Xml as a string.

第2步，您唯一需要做的窍门"是将C#输出通过Xslt模板传递，以便将其视为Xml，而不是字符串内容.

Step 2, the only 'trick' you need is to pass the C# output through a Xslt Template so it's treated as Xml, not String content.

<xsl:template name="MyXsltConcatTemplate">
     <xsl:param name="param1" />
     <xsl:element name="field">
          <xsl:value-of select="$param1" disable-output-escaping="yes" />
     </xsl:element>
</xsl:template>

disable-output-escaping ="yes" 是使这项工作有效的原因.

disable-output-escaping="yes" is what makes this work.
