Syntax: kf:element_at( object, index )

Select an element at the position specified by index. This function is used when a field name is unnamed and is instead referenced by number (position).

For example, using the following data source:

Example 1:

@ kf:element_at(rows,1)

Returns:

• /nl/
• /studyScreen?sourceId=11263
• /studyScreen?sourceId=270814
• /studyScreen?sourceId=604

Example 2:

@ kf:element_at(rows,2)

Returns:

• 1
• 1
• 1
• 1

Syntax:kf:fill_elements(path,'fieldname')

Note: You can enter the formula manually or generate it automatically by choosing the Selection Option Select all <field_name> elements in all <parent> elements, adding blanks for missing <field_name> elements.

This function is used to “fill in” blanks for an element that is not included in every record. This is useful for data alignment.

For example, using the following data source:

Example 1:

@ /player/first-name Returns: Anders, Maurice, Wayne

@ /player/nickname Returns: Rocket, The Great One

As is, the data incorrectly aligns Anders with the nickname, Rocket, and Maurice with the nickname, The Great One.

Use kf:fill_elements to align this data correctly:

@ kf:fill_elements(/player,'nickname')

Returns: <blank>, Rocket, The Great One

Example 2:

@ kf:fill_elements(/player/team,'wha')

Returns: 1974-1978, <blank>, 1978-1979

Note: This function does not work for nested arrays.

Syntax: kf:names(object)

Note: You can enter the formula manually or generate it automatically by choosing the Selection Option Select all field names in <parent> element.

The kf:names function returns the names of all fields contained in an element. This is useful when the field names identify categories such as demographics or countries.

Example 1:

For example, Facebook can return page fans data by gender and age. To create a list of these categories for a table column for a bar/line chart x-axis, use:

@ kf:names(data/values/value)

Which returns data shown in the following image:

Compare with @ kf:names(/data/values/value/M.25-34) which returns only value M.25-34

More examples:

The following show more examples using the data source featured in the previous function (kf:fill_elements).

@ kf:names(/player[1]/team) Returns: name, wha

@ kf:names(/player/team) Returns: names for all items in player: name, wha, name, nhl, name, wha, nhl

@ kf:names(/player[1]) Returns: first_name, last_name, team

Note: Unnamed fields cannot be selected directly; see kf:element_at (described at the top of this table).
