Convert an HTML Document to XHTML with HTML Tidy
HTML Tidy was initially developed as a tool to clean up HTML, but it is an XML tool, too. This hack shows you how to use HTML Tidy to make your HTML into XHTML.
HTML Tidy was initially developed at the W3C by Dave Raggett (http://www.w3.org/People/Raggett/#tidy). Essentially, it’s an open source HTML parser with the stated purpose of cleaning up and pretty-printing HTML, XHTML, and even XML. It is now hosted on Sourceforge (http://tidy.sourceforge.net). You can download versions of Tidy for a variety of platforms there.
Example 2-10 shows an HTML document, goodold.html, which we will run through HTML Tidy.
Example 2-10. goodold.html
<HTML> <HEAD><TITLE>Time</TITLE></HEAD> <BODY style="font-family:sans-serif"> <H1>Time</H1> <TABLE style="font-size:14pt" cellpadding="10"> <TR> <TH>Timezone</TH> <TH>Hour</TH> <TH>Minute</TH> <TH>Second</TH> <TH>Meridiem</TH> <TH>Atomic</TH> </TR> <TR> <TD>PST</TD> <TD>11</TD> <TD>59</TD> <TD>59</TD> <TD>p.m.</TD> <TD>true</TD> </TR> </TABLE> </BODY> </HTML>
Assuming that Tidy is properly installed, you can issue the following
command to convert goodold.html to the XHTML
document goodnew.html using the
-asxhtml
switch:
tidy -indent -o goodnew.html -asxhtml goodold.html
The -indent switch indents the output, and the
-o switch names the output file. Tidy will issue
warnings if necessary, and provide tips that encourage accessibility.
The new file goodnew.html looks like Example 2-11.
Example 2-11. goodnew.html ...
