停止脚本在CSV列标题上循环？

Question

此代码在我的桌面上创建一个新CSV。它从源CSV中提取链接。源CSV是一列URL链接。在输出新CSV中，它会创建一个列 标题为Column_1_Name（我希望它在第1行），然后在下一行，它将提取的文本放在URL scrape中。问题是，在CSV（第3行）的下一行，它再次重复列标题（Column_1_Name），然后重复下一个提取的数据。然后再次Column_1_Name标题（第5行），然后提取数据。等等。

我需要知道如何将Column_1_Name标头放入新CSV中，然后让代码继续通过数据提取循环，直到它完成源CSV中所需的URL数。 /强>

以下解决方法对您有所帮助：

'Start at line 2 in the file (below)
SET !LOOP 2
SET firstFolder "/Users/preston/Desktop/"

'Setting the column header in our output CSV File
URL GOTO=www.google.com
SET !EXTRACT <SP>Column_1_Name<SP>
SET firstFolder EVAL("({{!LOOP}} == 2) ? '{{firstFolder}}' : '';")
SET !ERRORIGNORE YES
SAVEAS TYPE=EXTRACT FOLDER={{firstFolder}} FILE=New_File_Name{{!NOW:mm-dd-yy}}
SET !ERRORIGNORE NO
SET !EXTRACT NULL

SET !DATASOURCE /Users/preston/Desktop/SourceCSV_File.csv
SET !DATASOURCE_COLUMNS 2
'Increase the current position in the file with each loop
SET !DATASOURCE_LINE {{!LOOP}}
