Cross-linking

  \Link[@1 @2]{@3}{@4}...\EndLink

Creates

  <a href="@1#@3" name="@4" @2>...</a>

When @1 is empty, TeX4ht will derive its value automatically. The derived value will be the file name containing the target @3.
\Link may be followed by -, if TeX4ht needs not automatically determine (for other \link commands) the file containing @4. In the present of such a flag, TeX4ht can spare a definition of one macro.
The component [@1 @2] is optional. If omitted, @1 and @2 are assumed to be empty.
The href attribute is omitted when @1 and @3 are empty.
The name attribute is omitted when @4 is empty.

Example

  \Link{a}{}...\Endlink .....  \Link{}{b}...\EndLink
  \Link[http://foo  id="fooo"]{a}{b}...\EndLink
  \Configure{Link}..............4

Configures \Link...\EndLink so that

#1	replaces `a`
#2	replaces `href=`
#3	replaces `name=`
#4	replaces ‘#’. If empty, the older value remains in effect.

Example

  \Configure{Link}{a}{href=}{name=}{}
  \Configure{Link}{ref}{target=}{id=}{\empty}
  \Configure{?Link}..............1

#1	insertion before broken links

To help with debugging

\LinkCommand...................1 <= i <= 6

Creates a \Link-like command

#1	tag name
#2	href-like attribute
#3	name-like attribute
#4	insertion
#5	`/`, if empty element
#6	replacement for # (ignored if absent)

Example

  \LinkCommand\JSLink{a,\noexpand\jsref,name}
  \def\jsref="#1"{href="javascript:window.open(’#1’)"}
  \JSLink{a}{}xx\EndJSLink
  \Link{}{a}\EndLink       % or \JSLink{}{a}\EndJSLink
  \Configure{XrefFile}.....................1

#1	names cross-references of files (appends #1 to `)F` and `)Q` entries of the `.xref` files). Applicable mainly implicitly within `\Link` commands.

  \Tag.....................................2

#1	label
#2	content

  \Ref.....................................1
  \LikeRef.................................1

#1	label

\Tag and \Ref are tex4ht.sty commands introduced cross-referencing content through .xref auxiliary files.

\LikeRef is a variant of \Ref which doesn’t verify whether the labels exit. It is mainly used in \Link and \edef environments.

  \ifTag ..................................3

#1	quetioned tag
#2	true part
#3	false part

  \LoadRef-[prefix]+{filename.ext}{pattern}

Load the named xref-type file

.xref	optional --- `.xref` is assume for a default
+	optional --- asks `\Ref` and `\LikeRef` commands to use expanded tags `filename::tag`, instead of just `tag`
[prefix]	optional --- asks just for tags starting with the specified prefix.
-	optional --- deletes the prefixes from the loaded tags
{pattern}	to be included only when `[prefix]` or `+` are included. States how tags are to be addressed, with the parameter symbol ‘#1’ specifying the loaded part.

Example

  % a.tex
  \LoadRef-[to:]{b}{from:#1}      \Ref{from:filename}
                               \LikeRef{from:filename}
  % b.tex
  \Tag{to:filename}{\FileName}

Example


  \LoadRef-[)F]{file}{)Ffoo##1}
  \LoadRef-[)Q]{file}{)Qfoo##1}
  \Configure{XrefFile}{foo}   \Link...\EndLink
  \LoadRef{another-file}
