Import from XML File#
The Import from XML File allows users to import data directly from XML files, specifying the data sheets.
The Import from XML File task is divided into two tabs:
the Options tab
The Options tab#
The Options tab follows the structure shown in the Import Overview page.
The Xml Configuration tab#
The Xml Configuration tab is divided into three panes:
Parsing options: users can find the parsing options.
Import options: users can find the import options.
Table preview: users can visualize a preview of their imported tables.
Parsing options
Within this pane, users can set and configure the following options:
Number separators: users can define symbols to mark thousands and decimals in numbers. You can select the symbols from the Thousands and Decimals drop-down lists.
Missing string: users can enter the string to remove from the dataset.
Key for types: users can specify the string to be used to identify the type.
Import options
Within this pane, users can find and set the following options:
Remove the most external tag when importing dataset: if selected, the most external tag is removed from the imported file.
Remove empty rows: if selected, it removes empty rows from the imported dataset.
Add group columns: If selected, it adds an extra column containing the group id or file structure.
Remove empty columns: if selected, it removes empty columns from the imported dataset.
Add an attribute containing filename: if selected, it adds an extra column with the name of the file to the dataset.
Strip spaces: if selected, it removes the empty columns from the imported dataset. For example, the string ” class ” will be imported as “class”.
Case sensitive:if selected, upper cases are considered different from lower cases.
Compress white spaces: if selected, it compresses contiguous occurrences of white spaces in one single occurrence. For example the string “university program” would be imported as “university program”.
Save response header: available in the Import from JSON File and in the Import from XML File tasks when importing from a Http Server, allows to save the response’s headers, by adding two extra columns to the dataset: one containing the headers’ names, and another one containing the headers’ values, so that each row contains the header name and its corresponding value.
Turn off smart type recognition: if selected, prevents automatic recognition of data types. This option is useful when manual identification is preferable, for example when there is the risk of a code being misinterpreted as a date.
