An information processing apparatus includes a selector unit that selects a character string, an element specifying unit that specifies a first element from among elements defined by a document structure definition controlling a document into which the selected character string is inserted, an insertion destination specifying unit that specifies an insertion destination within the document, and a shifting unit that determines whether the first element is able to have a character string as an element, searches the document structure definition for a second element that is lower than the first element and is able to have a character string, searches the document structure definition for an element to be inserted between the first element and the second element, generates an insertion element by interpolating between the first element and the second element with the element to be inserted, and shifts the insertion element to the insertion destination.
