Question

我有一个类似于以下内容的flatfile：

brand: bmw {CR}{LF}    
{CR}{LF}
engine: 2000cc {CR}{LF}    
{CR}{LF}
description: bla bla{CR}{LF}
{CR}{LF}
bla bla bla{CR}{LF}
bla bla bla{CR}{LF}
{CR}{LF}
bla{CR}{LF}
{CR}{LF}
remarks: none

要分隔品牌，引擎，说明和备注，我可以使用＆＃34; {CR} {LF} {CR} {LF}＆＃34;，但由于说明包含＆＃34; {CR} { LF} {CR} {LF}＆＃34;此外，它可以是描述中的任意数量的行。

我想得到一个xml：

<brand>bmw</brand>
<engine>2000cc</engine>
<description>bla bla{CR}{LF}{CR}{LF}bla bla bla{CR}{LF}{CR}{LF}bla bla ....</description>
<remarks>none</remarks>

这是否可以使用flatfile架构？

Answer 1

您最初可能无法在描述中保留CR LF，但是您可以创建一个允许您在之后重新组合它的结构。

1）使用标签来识别包含第一条描述线的标签。 2）为后续描述行创建一个没有标记的重复记录。 3）然后，您可以使用累积连接将两组描述行映射到目标模式中，然后添加换行符。

请参阅下面的示例模式。

输出。

P.S。我将文字{CR} {LF}放入连接functoid而不是CR＆amp; LF字符。要获得真实的，请使用返回System.Environment.NewLine的脚本functoid;它传递给两个连接functoid。
