To String - Maple Help

Worksheet

 ToString
 convert a XML tree data structure representing a worksheet in the specified format and return it as a Maple string

 Calling Sequence ToString(xmlTree, format=output_format)

Parameters

 xmlTree - Maple XML tree; worksheet format=output_format - (optional) equation; output_format can be one of "mws", "maple8_xml", or "mw" (default)

Description

 • The ToString(xmlTree) calling sequence formats the XML document xmlTree representing a Maple worksheet as a MWS document (stored as a Maple string).
 It is assumed that the XML document that is written to a string represents a valid worksheet. (Maple performs only a surface check.)
 The returned XML document is formatted without line breaking or indentation of any kind. As a result, regardless of size, the document is returned as a single line of text.

Examples

The following examples demonstrate how a Maple XML tree data structure can be converted and returned as a string.

The ToString command converts the XML tree data structure doc and returns it as a Maple string str.

The string str is parsed and converted back to an XML tree data structure doc1 by using the FromString command.

 > $\mathrm{doc1}≔\mathrm{FromString}\left(\mathrm{str}\right):$

The Display command launches the worksheets. The Display command launches the string str and the XML tree doc1. For information on Display command parameters, see Worksheet[Display].
