The Read Line activity reads lines from a text file. You can use the Read Line activity to read lines from a text file and pass them to another activity using published data.
This activity replaces functionality in the Manage Text File legacy activity from Opalis 6.3.
Configuring the Read Line Activity
Use the following information to configure the Read Line activity.
|File||Type the path and name of the file that you want to read the text from, or click the ellipsis button (...) and browse for it.|
|File encoding||Click the ellipsis button (...) and select the format that the file is encoded in from the File encoding drop-down list. Verify that you select the correct encoding format. If the file uses a different encoding format, the activity fails.|
|Line numbers||Type the line numbers of the text that you want to read from the file that you specified.
- To specify a range of lines, use a hyphen: 1-3. This reads lines 1 to 3.
- To specify specific lines, use a comma: 5,7,9. This reads lines 5, 7, and 9.
- Combine the range and specific lines: 1-3,5,7,9. This reads lines 1 to 3, and lines 5, 7, and 9.
- To specify from a specific line to the last line of the file, type the line number, hyphen, and END: 4-END. This reads lines 4 to the last line of the file.
- To specify from a specific line to a line relative to the last line of the file, type the line number, hyphen, the less-than sign, and the line number relative to the end line: 4-END<3. If the file has 20 lines, this reads lines 4 to 17 from the file. <3 represents the third line from the end.
- To specify the last number of lines, type LASTLINES, colon, and the last number of lines that you want to delete: LASTLINES:10. This reads the last 10 lines of the file.
- Combine different types of operations: 1-5, 8, 10-END<20, LASTLINES:10. This reads lines 1 to 5, line 8, line 10 to the 20th line from the end, and the last 10 lines. Do not overlap lines or line ranges when combining operations. For example, 5-END, LASTLINES:10 fails because the 5-END operation already reads to the end, so the LASTLINES:10 operation cannot succeed because the lines are already read, and the activity fails. Important: Do not specify lines numbers that do not exist in the file, and do not specify a line number more than once, or the activity will fail.
The following table lists the published data items.
|File name||The file name of the text file that was read.|
|File encoding||The file encoding format that you selected in the File encoding field.|
|Line text||The text of the line that was read.|
|Line number||The line number of the text that was read. A published data item is created for each line that was read.|
|Line numbers||The line number range that the user typed in the field.|
