Re: [docbook-apps] line breaks in </lineannotation>

Hi Sam,
I don't think using normalize-space() would be satisfactory, because that 
function returns text only, and would remove the html markup that makes it a 
cross reference.   Applying normalize-space to the xref would return 
nothing, because an xref element is empty.

You don't want to mess with the markup, only with the text nodes of cross 
reference targets that contain carriage returns.  There is no specific mode 
for that, but the no.anchor.mode comes close.  It is used when generating 
cross references because it prevents nested links (i.e., no link anchors 
inside the link text).  Since that is a mode, you can use it to match only 
the text nodes in titles as follows to map any line feeds in the title to 
spaces:

<xsl:template match="title/text()" mode="no.anchor.mode">
  <xsl:value-of select="translate(., '&#10;', '&#32;')"/>
</xsl:template>

This seems to work, and I haven't noticed any side effects, but be sure to 
test it.

Hi,
if you look at
http://clisp.podval.org/impnotes/mt.html#mt-unsafe
you will see a spurious line break:

(INCF (GETHASH x global-ht 0)) ; see Section 32.5.2.5, “Hash Tables,
Sequences, and other
  mutable objects”

there should not be a line break between "other" and "mutable".

the sources (http://clisp.podval.org/impnotes-src.zip) impext.xml:

-----------------------------------
<section id="mt-mutable"><title>Hash Tables, Sequences, and other
  mutable objects</title>
...
<programlisting language="lisp">
(&incf; (&gethash; x global-ht 0))<lineannotation>see <xref
linkend="mt-mutable"/></lineannotation>
....
-----------------------------------

template:

-----------------------------------
<xsl:template match="programlisting[@language = 'lisp']/lineannotation">
 <strong>&#9;;&#160;</strong> <!-- TAB + ; + &nbsp; -->
 <xsl:apply-imports/>
</xsl:template>
-----------------------------------

my question is: should I use normalize-space myself
(the following is probably wrong, I hope you will correct that for me):

-----------------------------------
<xsl:template match="programlisting[@language = 'lisp']/lineannotation">
 <strong>&#9;;&#160;</strong> <!-- TAB + ; + &nbsp; -->
 <xsl:value-of 
select="normalize-space(.)"><xsl:apply-imports/></xsl:value-of>
</xsl:template>
-----------------------------------

or is this a bug which could be fixed at the source?

thanks!
