Tika Parser URL Input

This node has the same function as the Tika Parser node, which is to parse any documents that are supported by Tika. The difference is that this node takes file paths from a string column as input. The type of the files can be selected in the configuration dialog. Users have the choice between selecting the file extensions, or the MIME-types. What kind of information that are to be extracted from the file (metadata and content) can also be selected in the dialog. If possible, user can also extract files that are embedded in the input files, such as attachments in E-mails, etc, and store them in a specified directory. Authentication setting is also provided to parse any encrypted files.

Options

File path column: The column containing the paths to files to parse.
Choose which type to parse: Specify how to choose the file types that are to be parsed. There are two options, either through the file extensions or the MIME-types.
File Extension: If selected, the list of all file extensions that are supported by Tika will be shown.
MIME-Type: If selected, the list of all MIME-types that are supported by Tika will be shown. For more information about MIME-types and their extensions, check here .
Metadata: The list of all available information that could be parsed from the files by Tika. For more details about the metadata, check here .
Create error column: If checked, an additional error column will be created. This string column will contain any error messages that appear while parsing the files.
New error output column: The name of the new error column.
Extract attachments and embedded files: If checked, any embedded files that are contained in the input files would be extracted and stored in the output directory.
Ouput directory: Specify the directory where the extracted files should be stored. If the specified directory doesn't exist, the node will try to create it.
Parse encrypted files: If checked, the node will try to open any detected encrypted files using the given password. If the password is invalid, a warning will be given.
Enter password: Specify the password for any encrypted files in the directory. Note: this password will be used to open all encrypted files in the directory.
