The issue:
Background: When working with XInclude, I have sometimes had problems
with links: COnsider the "main document". Question: how should one go on
when creating a anchor link that leads to a fragment in one of the
included documents?
Use links like (3), not links like (2). See below.
However links like (3) do not work in XXE. They work in the browser when
generating a preview using XXE 6.4 (menu item "XHTML|Preview"). See below.
This seems to be ann "issue" (as in «I need to learn
how to do this») also, for instance, in Prince XML, which uses Libxml2
for its XInclude functionality.
BUt now I have got the same issue in XXE. I attach two documents - a
main document and an included document. In the main document (called
"00-compound-doc.xht") there are 3 clickable links (anchor tag links):
1. First link is to a place inside the main document itself.
2. Next link is to a place in the included document. The link includes
the filename of the included file plus the fragment ID for the very
fragment to which the link leads. Thus the URL has the form
filename.xht#fragment
3. The third link goes to the same place as the second link. However
this link is a pure fragment URL - thus the URL has the form
"#fragment".
The problem si that the first linke works (which is not a problem ...),
but second and third linnk do not work.
--> "00-compound-doc.xht" is *invalid*. The red icon found at the
bottom/left of XXE main window shows you that your "00-compound-doc.xht"
has a severe validity problem.
I had to replace:
<xi:include href="00-included-doc.xht"
xmlns:xi="http://www.w3.org/2001/XInclude"; />
by:
<xi:include href="00-included-doc.xht" xpointer="TheIncludedDocument"
xmlns:xi="http://www.w3.org/2001/XInclude"; />
--> Once "00-compound-doc.xht" is fixed:
1) <a href="#LastFillerText"> works fine.
2) <a href="00-included-doc.xht#TheIncludedDocument">
Does not work because you are using a ".xht" file extension. A ".xht"
file could contain anything. I mean, XXE will not follow a link pointing
to a non-HTML file (e.g. a PDF file).
I made this simple change in
<XXE_install_dir>/addon/config/xhtml/xhtml_support_base.incl:
---
<linkType>
<link match="html:a[@href]" href="@href"
includePath="\.[xs]?htm(l)?$" />
---
replaced by (notice the new includePath pattern):
---
<linkType>
<link match="html:a[@href]" href="@href"
includePath="\.[xs]?ht((m)?l)?$" />
---
and now "Follow Link" works, but not as I expected it: I expected XXE to
open your "00-included-doc.xht".
3) <a href="#TheIncludedDocument"> does not work in XXE. However this
link works fine in the preview generated by XXE 6.4 (menu item
"XHTML|Preview").
It's not really an XXE bug. I would say that you have uncovered a
conceptual problem. There is no such conceptual problem with DocBook
(flat ID space) or with DITA (well-thought specialized inclusion mechanism).
For now, I don't see how to solve this problem. Sorry.
If this is a bug, then I could imagine that this link is related to the
"preview compound document" bug that told about some days ago (when I
reported that the Preview function would not allow me to preview a
compound document).
No, not at all.
As such the bug could be working in the upcoming
version of XXE. (However, after a brief test in the "translation
version" of XXE 6.4 indicated that the preview functionality for
compound XHTML docs did not work yet.)
The bug has been fixed in XXE 6.4. For example, once your xpointer
omission is fixed, it was possible to preview "00-compound-doc.xht" in
Firefox.
