Line Reader

Read lines from a file or URL. Each line will be represented by a single string data cell in a single row. The row prefix and column header can be specified in the dialog.

Options

URL field

Select the file to be read using the Browse button. You can also enter a URL (such as http://some_host/some_path) or assign a variable representing the target file using the variable button on the right.

Row header prefix

The prefix of the row headers (amended by a running index).

Column header

The name of the single output column.

Use first line as column header

If selected, the first line in the file will be used as column header. If it is used together with the "Limit number of rows" option it does not count as row.

Skip empty lines

If set, empty lines are skipped. This also includes lines only containing white space characters such as spaces or tabs.

Limit number of rows

If set, the node will not read more lines than specified. If "Skip empty rows" is selected, empty rows do not count as valid rows.

Match input against regex

If set, lines that do not match the specified regular expression are skipped.
