powershell：将foreach循环数据从csvfile递增到xml输出文件 [英] powershell : increment foreach loop datas from a csvfile to an xml output file
问题描述
您能帮我实现一个计数器，以便从内部csv生成带有多个元素的xml文件吗？
Could you help me implementing a counter in order to generate an xml file with multiple element from a csv inside?
这是csv文件

和代码
我在屏幕上的返回很好，但由于我没有打电话值，不能递增。
目前，我尝试过的所有操作均出现了问题（只有最后一个结果似乎会导致其他所有崩溃）
My return on the screen is good but as I am not calling the value, it can't be incremented. And for the moment all the things I've tried has a bad issue (only the last result appears to crash every other one)
请帮助我

推荐答案
我从上次修改代码以来错误控制，因为我认为这是您将 while 循环更改为 foreach 循环的原因。
I have revised my code from last time to build in error control, because I believe that was the reason you changed the while loop into a foreach loop.
下面的代码仍然使用while循环，因为对我来说，这使得处理计数器更加容易。
我确实更改了将项目和文档模板插入到项目中的方式。代码，因为Here-Strings倾向于破坏代码格式，使其更难阅读。现在它使用了递延变量扩展，我从这个答案
这样，可以在代码的早期定义模板，而不会破坏缩进，并在以后需要时进行扩展。
The code below still uses the while loop because for me that makes it easier to handle the counters.
I did change the way the item- and document templates are inserted in the code, because Here-Strings tend to break code formatting, making it harder to read. Now it uses a deferred variable expansion, I leaned from this answer.
By doing that, the templates are defined early in the code without breaking indentation and are expanded when needed later on.
我还更改了捕获方式可能的错误。后来，我使用了一个列表对象，通过在错误项之前添加两个额外的列来捕获所有错误类型和项： ErrorType 和 ErrorDescription 。
I also changed the way you capture the possible errors. Beow I'm using a single List object to capture all error types and items by prefixing two extra columns to the error-item: ErrorType and ErrorDescription.

# The Here-Strings use SINGLE quotes, so the variables inside are now NOT expanded.
# We'll do that later in the code using $ExecutionContext.InvokeCommand.ExpandString($itemTemplate)

}
一些解释：
Some explanation:
while（$ restant -gt 0）循环只会比 foreach（$ liste中的$ item）容易得多，因为它会测试是否还有要处理的项目。
The while ($restant -gt 0) loop simply makes it a lot easier then a foreach($item in $liste), because it tests if there are still items to process.
-
$ itemCount = [数学] :: Min（$ maxItemsPerXml，$ restant）为您设置的项数在$ maxItemsPerXml中，但永远不会超过剩余的项目。
$itemCount = [math]::Min($maxItemsPerXml, $restant)gets you the number of items you set in$maxItemsPerXml, but never more than there are items left.
下一个循环中的 $ itemCount 变量 $ xmlItems = for（$ i = 0; $ i -lt $ itemCount; $ i ++）遍历此最大项目数，同时，我们捕获变量 $ xmlItems
we use that $itemCount variable in the next loop $xmlItems = for ($i = 0; $i -lt $itemCount; $i++) to iterate over this maximum number of items and at the same time, we capture whatever the loop outputs in variable $xmlItems
在此循环中，我们首先对每个项目的每个字段进行一些测试，如果测试失败，则报告在变量 $ errorList 。如果某项未通过测试，则将其从XML输出中省略，因此我们需要使用 $ itemCount = [math]调整变量。 $ itemCount :: Min（（（$ itemCount +1），$ restant）
再一次，我们使用[math] :: Min（）来确保我们永远不会超出剩余的项目数。
inside this loop we first do some tests on each field per item and if a test fails, we report that in variable $errorList. If an item has failed the tests, it is omitted from the XML output, so we need to adjust variable $itemCount with $itemCount = [math]::Min(($itemCount + 1), $restant).
Again, we use [math]::Min() to make sure we never go beyond the remaining number of items.
如果所有测试均通过，则该项目将输出为XML < Document> ..< / Document> 节点并收集在 $ xmlItems
if all tests pass, the item is output as XML <Document>..</Document> node and collected in $xmlItems
然后，如果我们完成为（$ i = 0; $ i -lt $ itemCount; $ i ++）循环，我们最多收集了 $ maxItemsPerXml 个xml节点，我们需要保存XML。
then, if we finished the for ($i = 0; $i -lt $itemCount; $i++) loop we have collected a maximum of $maxItemsPerXml xml nodes and we need to save the XML.
保存后，在重新进入while循环之前，我们需要调整各种计数器：
after saving, we need to adjust the various counters before we re-enter the while loop:
- 使用
$ xmlFileCount ++ - 下一个文件的文件计数器增加$ c> $ restant-= $ itemCount
- 将索引号
$ currentItem设置为下一个$ currentItem + = $ itemCount
- the filecounter is incremented for the next file with
$xmlFileCount++ - the number of remaining items is adjusted with
$restant -= $itemCount - the index number
$currentItemis set to the next value in the total array with$currentItem += $itemCount
最后，我们检查 $ errorList 中包含任何内容，如果有，我们编写一个CSV文件 C：\temp\Errors.csv 我们发现的所有错误
finally, we check if the $errorList has anything in it, and if so, we write a CSV file C:\temp\Errors.csv with all errors we have found
全部完成！
