# Description: Adds <VATMODE>X</VATMODE> XML tags to files arriving from server, underneath each RECORD CODE line.
# Script tested and works using:
# - Powershell v5.1 on Windows 10 Pro
# - Powershell v4.0 on Windows Server 2008 R2.
# - Does NOT work on Powershell v2.0

我正在尝试实现与this类似的功能，但增加了复杂性。这些是每天从服务器到达的XML文件，并放入单个文件夹以导入到会计系统中。会计系统不会导入文件，除非每个<VATMODE>X</VATMODE>父项下都有子RECORD CODE。这些XML文件有两种可能性：逐个或分批。它们具有不同的名称，具有连续递增的数字和不同的前缀。例如：NX1000060.xml或NX1000061.xml或ABN000028.xml，依此类推。
# Regex to match RECORD CODE lines
$regEx = "\W\w{6}\s\w{4}\W.+"
#Regex to match exactly <VATMODE>X</VATMODE>
$vatModeExists = "\W\w{7}.\w\W{2}\w{7}."
# Assign the VATMODE tag, preceding it with three tabs for proper indentation
$vatModeTag = "`t`t`t<VATMODE>X</VATMODE>"
# Get all XML files in the directory
$files = Get-ChildItem -Path "C:\XML_dumping" -Filter *.xml
# Get the number of XML files in the directory
$numberOfFiles = (Get-ChildItem -Path "C:\XML_dumping" -Filter *.xml | Measure-Object).Count
for ($i=1; $i -lt $numberOfFiles; $i++) { # Loop through each file separately
$content = (Get-Content $files[$i - 1]) # Scan the contents of each file
if ($content -match $vatModeExists) { # If <VATMODE>X</VATMODE> is detected in the file...
break # ...then do not process the file (skip it)
}
# Get the matched RECORD CODE lines
$found = $content -match $regEx
for ($j=0; $j -lt $found.Length; $j++ ) { # Loop through each matched RECORD CODE line
echo $found[$j] $vatModeTag # Insert <VATMODE>X</VATMODE> right under RECORD CODE line
# save the files that now have VATMODE inserted into them, but how?
}
}
上面的脚本应该在每个RECORD CODE行下附加VATMODE标记，如下面的输出所示。
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<EXPORT>
<IMPORTMODEL>NEX</IMPORTMODEL>
<SESSION>1000060</SESSION>
<CUSTORDERS>
<RECORD CODE="NX0100096">
<VATMODE>X</VATMODE>
<INPUTDATE>19/07/2017</INPUTDATE>
<!--...and so on...-->
在Powershell ISE中，脚本运行正常（用于我的视觉检查），但如何插入VATMODE并保存我已添加VATMODE的文件？

我使用[regex]::replace，它对我有用。正则表达式中的括号用于检索$ 1中的值。此外，我在-lt循环中的-le替换了代码for。
# Regex to match RECORD CODE lines
$regEx = "\W\w{6}\s\w{4}\W.+"
$regExParen = "(\W\w{6}\s\w{4}\W.+)"
#Regex to match exactly <VATMODE>X</VATMODE>
$vatModeExists = "\W\w{7}.\w\W{2}\w{7}."
# Assign the VATMODE tag, preceding it with three tabs for proper indentation
$vatModeTag = "`t`t`t<VATMODE>X</VATMODE>"
# Get all XML files in the directory
$files = Get-ChildItem -Path "C:\Users\user1\Documents\XML_dumping" -Filter *.xml
# Get the number of XML files in the directory
$numberOfFiles = (Get-ChildItem -Path "C:\Users\user1\Documents\XML_dumping" -Filter *.xml | Measure-Object).Count
for ($i=1; $i -le $numberOfFiles; $i++) { # Loop through each file separately
$content = (Get-Content $files[$i - 1] -raw) # Scan the contents of each file
if ($content -match $vatModeExists) {
# If <VATMODE>X</VATMODE> is detected in the file...
echo "<VATMODE>X</VATMODE>"
break # ...then do not process the file (skip it)
}
# replaces in $content the reg. expression with VATNUMBER
$content= [regex]::replace($content, $regExParen, ('$1'+"`r`n"+"VATNUMBER"+"`r`n"))
# Insert <VATMODE>X</VATMODE> right under RECORD CODE line
echo $content
# save the files that now have VATMODE inserted into them, but how?
$content | Out-File -encoding utf8 $files[$i - 1]
}

所以我试着拿出一些东西。但与你要求的有点不同。
# Assign the path where the XML files are getting dumped as they arrive from the server
$fileName = "*.xml"
# Assign the regular expression patterns
$regEx = "\W\w{6}\s\w{4}\W.+"
$vatModeExists = "\W\w{7}.\w\W{2}\w{7}."
# Assign the VATMODE tag, preceding it with a line break and three tabs for proper indentation
$vatModeTag = "`n`t`t`t<VATMODE>X</VATMODE>"
$Output
foreach($file in $fileName){
if ((Get-Content $file) -notmatch $vatModeExists){
if($file -match $regex) { # if RECORD CODE line is found
$file += $vatModeTag # append VATMODE after each RECORD CODE line
}
$output += $file
}
}
Set-Content -path SomeFile.xml -Value $output
