HTML export: internal links broken

HTML export: internal links broken

[Sebastian Rose]

There is small bug in the XHTML export. Internal links point to nowhere.

* Example

*** In the orgfile:

    This [[Some Heading][Link]] should link to '*** Some Heading'.

*** After export, HTML file:

    This <a href="#Some--Heading">Link</a> should link to '*** Some
    Heading'.


There is no anchor defined with that name in the exported HTML. There
are two possibilities to change this:

    1) define the anchor next to the heading:
       <a id="Some--Heading" />

    2) If the link pionts to a heading, use the ID of the heading in the
       link: 
       ... <a href="sec-3.2.1">Link</a> to '*** Some Heading'.



The second one is the one I would prefer, but that would mean to handle
links to headings differently from links to user defined anchors. But it
would keep the nesting of section containers clean.

Hi Sebastian,

this is not really a bug.  Internal links in Org are fuzzy links, they  
do a text search.
During HTML export I am only implementing explicit targets: pieces of  
text enclosed in <<...>>

So if you write

> * <<Some Heading>>
>
> ** <<Some other heading>>
>
> *** Some <<third>> heading
>
>    This [[Some Heading][Link]] should link to '*** Some Heading'.
>
>    This [[Some other heading][Link]] should link to '*** Some other  
> heading'.
>
>    This [[third][Link]] should link to '*** Some third heading',
>    even though only a single word is in the target.


then you will get a properly linked export:

> <div id="outline-container-1" class="outline-2">
>   <h2 id="sec-1">1 <span class="target">Some Heading</span> </h2>
>   <div id="text-1"></div>
>
>   <div id="outline-container-1.1" class="outline-3">
>     <h3 id="sec-1.1">1.1 <span class="target">Some other heading</ 
> span> </h3>
>     <div id="text-1.1"></div>
>
>     <div id="outline-container-1.1.1" class="outline-4">
>       <h4 id="sec-1.1.1">1.1.1 Some <span class="target">third</ 
> span>  heading</h4>
>       <div id="text-1.1.1">
>
>
> <p>
> This <a href="#sec-1">Link</a> should link to '*** Some Heading'.
> </p>
> <p>
> This <a href="#sec-1.1">Link</a> should link to '*** Some other  
> heading'.
> </p>
> <p>
> This <a href="#sec-1.1.1">Link</a> should link to '*** Some third  
> heading'.
> </p>
> </div>
> </div>
> </div>
> </div>

Hope this helps.
