Mathematica Import/Export Format

XHTML (.html, .htm, .xhtml, .xht, .xml)

Registered MIME type: application/xhtml+xml
XHTML markup language and file format.
XML-based reformulation of HTML.
XHTML is an acronym derived from Extensible Hypertext Markup Language.
Plain text XML format.
Describes the structure and aspects of the appearance of web pages.
Successor of HTML.
Published as a W3C recommendation in 2001.
  • Import fully supports XHTML versions 1.0 and 1.1.
  • Export generates documents conforming to XHTML 1.1.
  • Import["file.xhtml"] gives a plain text representation of an XHTML file.
  • Import["file.xhtml", "Data"] extracts tabular data from XHTML.
  • Export["file.xhtml", expr] creates an XHTML version of expr.
  • Export["dir", expr] translates expr to XHTML, saving the output in the specified directory.
  • Import["file.xhtml"] returns a string, representing the textual content of the file as formatted plain text.
  • Export["file.xhtml", expr] exports a notebook, a cell, a list of cells, or other notebook elements to XHTML.
  • Export always creates a complete XHTML document, and not merely a fragment of XHTML.
  • The output consists of one or more XHTML files and two directories, HTMLFiles and HTMLLinks.
  • Mathematica by default converts typeset expressions to GIF images when exporting to XHTML.
  • Mathematica can export Tooltip and Hyperlink expressions, creating HTML image maps if necessary.
  • Import["file.xhtml", elem] imports the specified element from an XHTML file.
  • Import["file.xhtml", {elem, suba, subb, ...}] imports a subelement.
  • Import["file.xhtml", {{elem1, elem2, ...}}] imports multiple elements.
  • The import format can be specified with Import["file", "XHTML"] or Import["file", {"XHTML", elem, ...}].
  • Export["file.xhtml", expr, elem] creates an XHTML file by treating expr as specifying element elem.
  • Export["file.xhtml", {expr1, expr2, ...}, {{elem1, elem2, ...}}] treats each expri as specifying the corresponding elemi.
  • Export["file.xhtml", expr, opt1->val1, ...] exports expr with the specified option elements taken to have the specified values.
  • Export["file.xhtml", {elem1->expr1, elem2->expr2, ...}, "Rules"] uses rules to specify the elements to be exported.
  • See the reference pages for full general information on Import and Export.
  • Save Selection As exports the selected part of a notebook as a web page.
  • Save As exports an entire notebook as a web page.
"Elements"list of elements and options available in this file
"Rules"full list of rules for each element and option
"Options"list of rules for options, properties, and settings
"Data"textual and numerical content from HTML table and list elements
"FullData"full tabular content, including empty HTML table and list elements
"Hyperlinks"list of strings, representing target URLs of hyperlinks
"Plaintext"XHTML document formatted as text
"Source"raw XHTML source as a single string
"XMLObject"symbolic XML representation of the entire document
  • Import by default uses the "Plaintext" element.
"Notebook"a Notebook expression
"NotebookObject"a NotebookObject expression
"Expression"an arbitrary Mathematica expression
"ConvertLinkedNotebooks"Falsewhether to convert linked notebooks to HTML
"CSS"Automaticwhat CSS stylesheet to use or link to
"MathOutput""GIF"how to represent typeset expressions
"Content"Falsewhether to export MathML content elements
  • Possible settings for "CSS" are:
Automaticcreates a CSS stylesheet from the Mathematica stylesheet
Nonedoes not create a stylesheet file or inline CSS style
"file.css"uses a stylesheet file
  • The following settings can be given for "MathOutput":
"GIF"converts all typeset expressions to GIF
"MathML"converts all typeset expressions to MathML
"DisplayForm"converts all typeset expressions to ASCII approximations of their appearance
"InputForm"converts all typeset expressions to their InputForm
  • See the "HTML" format page for complete information about supported Import and Export options.
