批處理文件提取許多.xml文件的xml標記的值

我需要幫助優化批處理文件以將多個xml文件的多個xml文件轉換爲.txt或.csv文件。批處理文件提取許多.xml文件的xml標記的值

.xml的格式都是相同的。他們的臨牀研究，並期待這樣的：

     The purpose of this study is to evaluate the efficacy and safety of levetiracetam for 
     treating alcohol withdrawal syndrome (AWS) in inpatients (vs. placebo). The primary come-out 
     parameter is the reduction of the total needed amount of diazepam for add-on treatment of 
     acute alcohol withdrawal symptoms. The secondary come-out parameter are - safety criteria 
     (AE) - reduction of alcohol withdrawal score over the days.

所以他們都使用相同的標記，我需要一些他們喜歡：

overall_official
lead_sponsor
official_title
results_reference
overall_status

到目前爲止，我試着用下面的代碼：

@echo off 
setlocal enabledelayedexpansion 
for %%a in (*.xml) do (
call :XMLExtract "%%a" "<results_reference>" location 
echo.!location!,%%~na 
) 
exit /b 

:XMLExtract file keystart location 
@echo off & setlocal 
for /f "tokens=3 delims=<>" %%a in ('Findstr /i /c:%2 "%~1"') do (
    set "loc=%%a" & goto :endloop 
) 
:endLoop 
ENDLOCAL & IF "%~3" NEQ "" (SET %~3=%loc%) ELSE echo.%loc% 
exit /b

我跑在命令行批：蝙蝠>> output.txt中或output.csv它完美地工作了overall_status，但所有其它標籤有問題，例如：

overall_offical：它停止後像他們一樣的10
其他標籤：文件名中列出（一如既往），但它背後的信息。

我真的很感謝任何關於如何解決這個問題的方法或者其他有效解決這個問題的方法。我對編程只有一點基本的瞭解，但我一定能夠將自己融入到任何簡單的解決方案中。最好的幫助將是一種優化批處理代碼以適應此問題的方法。如果缺少一些信息，我很抱歉，我會提供。

GOTO :EOF

你需要改變的sourcedir和destdir設置以適合你的情況。

這可能會給你一些想法。您還沒有在適當的echo小號

預計語法提供的輸出樣本，所以也許你會想前綴源文件名的每個輸出線（%%~na）運行：

thisbatchname標籤標記tag

我的方法是有%%a包含要被處理的文件名，%%L從文件的原始數據線和與%%P LEA的原始數據線丁空間被剝奪。

使用分隔符產生%%W到%%z的Tokenising %%P因爲每行包含1-3個可能的元素 - 標籤或數據。如果有第四個，那麼就會出現問題（標記爲malformed的文件被設置，儘管我沒有對它做任何事情 - 它將包含問題所在的文本[也可以設置爲%%P行...]）

因此，使用所需要的標籤作爲變量名，只需設置那些varnames到什麼或東西和使用if defined來解釋他們的狀態 - 這是對他們的運行時狀態工作數據逐行改變。

請注意，由於代碼的整個運行部分是一個龐大的代碼塊，因此必須使用rem而不是::以提供有用的註釋。

還要注意的是

(
commands 
)>file

將根據指定的（如果需要）

非常感謝Magoo，這對我有很大的幫助！代碼的工作方式與您的方式完全相同。儘管我還有一個額外的問題。我怎樣才能讓輸出結果顯示如下標籤：_tag_ - >信息或（甚至更好）：一個csv文件，它不會將每個單詞放在自己的列中，而是將整個標籤放入一列？所以，最後我想要一個文件，其中包括所有信息的概述。 –

如果你想要標籤，只需'echo %% P'或'echo %% L'而不是'echo'％'w％％y' – Magoo

好極了！謝謝：D –
