Converting HTML to LaTeX

My procedure for converting HTML to LaTeX is as follows.

Prerequisites

The following software installation and configuration must have taken place.

A recent version of Emacs needs to be installed.
A recent version of the W3 subsystem for Emacs needs to be installed.
The Emacs Lisp file w3-convert-to-xml.el needs to be loaded into Emacs. If path/w3-convert-to-xml.el is a full path to this file, then this can be accomplished with these Emacs keystrokes:
```
  M-x load-file RET path/w3-convert-to-xml.el RET
    
```
The file xp.jar from XP and the files xt.jar and sax.jar from XT (both packages by James Clark) must be findable via the environment variable CLASSPATH.
A Java implementation must be installed as a file named java which is findable via the environment variable PATH.

The following procedure will convert HTML to LaTeX:

If the HTML is in file.html, type these Emacs keystrokes to parse the HTML and display the formatted result in a Emacs buffer:
```
  M-x w3-find-file RET file.html RET
    
```
The formatted result is not used in this procedure; it is merely a byproduct.
Then type these Emacs keystrokes to convert the internal parse tree stored in the Emacs variable w3-last-parse-tree into XML:
```
  M-x w3-convert-to-xml RET
    
```
Switch to the W3 XML Conversion buffer using these Emacs keystrokes:
```
  C-x b W3 SPC XML SPC Conversion RET
    
```
Save the XML into the file file.xml using these Emacs keystrokes:
```
  C-x w file.xml RET
    
```
Let a full path to the file xhtml-to-latex.xsl be path/xhtml-to-latex.xsl. Run the following command to convert the XML into LaTeX:
```
  java com.jclark.xsl.sax.Driver file.xml path/xhtml-to-latex.xsl > file.tex
    
```
The resulting LaTeX file file.tex can be used as usual for LaTeX.
