<H1>Strip Specific Elements</H1>
<H2>SGML Comments</H2>
<P>Usually there should be no need to use sgml-comments, so why not
remove them at all? You can perform this by enabling the switch
<A HREF="../options.html#stripcomment"><KBD>STRIPCOMMENT</KBD></A> when invoking <KBD>hsc</KBD>.</P>
<P>Because of the numerous problems sgml-comments cause, you better use
<A HREF="spctags.html#comments">hsc-comments</A> anyway (see there also
for a discussion of these problems).</P>
<H2>Specific Tags</H2>
<P>..can be passed to the option <A HREF="../options.html#striptags"><KBD>STRIPTAGS</KBD></A>, separated by a
vertical bar (``<CODE>|</CODE>''). For example, to remove all physical styles, use
<KBD>STRIPTAG="B|I|U|TT"</KBD> when invoking <KBD>hsc</KBD>.</P>
<P>You can't strip tags, which have the <A HREF="../macro/flag.html">tag
modifier</A> <CODE>/SPECIAL</CODE> set. But this only concerns the
<CODE><!></CODE>-tag (use the above switch instead) and some of <KBD>hsc</KBD>'s
internal tags, which you should not strip anyway.</P>
<H2>Tags With External References</H2>
<P>These can be removed if you want to create a No-Net-version of your
document. Use the switch <A HREF="../options.html#stripexternal"><KBD>STRIPEXTERNAL</KBD></A> for this task. Tags which
are affected by this must have an URI-type attribute, which has the <A
HREF="../macro/attrib.html#modifier">attribute modifier</A>
<CODE>/STRIPEXT</CODE> set within <I>hsc.prefs</I>.</P>
<P>Currently, this affects only the tags <CODE><A></CODE>, <CODE><IMG></CODE> and
<CODE><LINK></CODE>. This can be useful if you want to create a
``no-net-version'' of your documents.</P>
<H2>Unneeded Linefeeds And White Spaces</H2>
<P>These can be removed, if you heavy use them to structure your
source, but don't want to waste bandwidth for them. You only need to
enable the switch <A HREF="../options.html#compact"><KBD>COMPACT</KBD></A>.</P>
<P>If now someone performs a "View Source" on your html object,it will
be less readable for him, but browsers won't care and display it the
same way. For example,</P>
<PRE>
This is a <B>complete</B>
waste of space...
</PRE>
will turn into
<PRE>
This is a <B>complete</B>
waste of space...
</PRE>
In particular, <KBD>hsc</KBD> does:
<UL>
<LI>replace tabs by a single blank
<LI>replace multiple blanks by a single one
<LI>replace multiple linefeeds by a single one
<LI>remove blanks preceeding a linefeed
<LI>remove blanks at beginning of line
</UL>
<P>Linefeeds and white spaces inside a tag call are also affected by
this option. The tag <CODE><PRE></CODE> temporarily suppresses this option,
until a <CODE></PRE></CODE> occures.</P>
