XHTML-file produced by LO while exporting - wrong decimal-separator for min-width

For me not reproducible with LO 5.0.3.2, Win 8.1

Could be I have to describe a little bit better:
1) Open the attached *.odt-file
2) Go to File → Export (not: File → Save As)
3) Select format XHTML
4) Save the file

There will appear a file with *.html (better should have *.xhtml).
Code is something like this:
...
<span style="display:block;float:left;min-width:0,635cm;">•</span>One bullet. Decimalseparator for margin on left ...

The min-width is set wrong here.

If doing File → Save As the code is totally different. It produces 
...
<li/>
<p style="margin-bottom: 0cm; line-height: 100%">One bullet. Decimalseparator for margin on left ...

No min-width is set here. The format isn't the same. For exporting a book (like Base-Handbook) it is unusable.

Thanks for your reply.  But unfortunately not reproducible for me.

I get: "<span style="display:block;float:left;min-width:0.635cm;">•</span>One bullet. Decimalseparator for margin on left side should be 0.6<span class="T1">"

Maybe a Linux only issue?

I have set back the user-profile here. Same behavior. I changed to the LO-Version of OpenSUSE - same behaviour. Changed to LO 4.1.6 (have installed many LO-versions parallel) - same behavior.

My System: OpenSUSE 13.2 64bit rpm Linux.

Seems we have to look for another person with Linux.

I get
min-width:NaNcm;

Setting to NEW.

Ubuntu 15.10 64-bit 
Version: 5.0.2.2
Build ID: 00m0(Build:2)
Locale: en-US (en_US.UTF-8)

Have tested a little bit more. The bug first appears with LO 4.0.0.3. Up to LO 3.6.7.2 the created code shows only '0' for min-with. So no min-with is defined at all.
Seem this feature has been added with LO 4.0. I will set this one as "regression". Could be it is wrong to set this as "regression", because the feature doesn't exist before.

Let's change to implementationError

Bug still exists with LO 5.3.1.1, OpenSUSE 42.1 Leap, 64bit rpm Linux.

Bug still exists with LO 6.0.5.2, OpenSUSE 42.3 Leap, 64bit rpm Linux.

Bug still exists in LO 6.2.5.2 on OpenSUSE 15 64bit rpm Linux

adjusting "$listLabelWidth" to "translate($listLabelWidth,',','.')" in the File filter/source/xslt/odf2xhtml/export/xhtml/body.xsl in Lines 2045 and 2107 fixes this for me, preparing a pull request at the moment...

I made a commit at https://gerrit.libreoffice.org/c/core/+/104544, this gerrit configuration is new to me, i usually only use git, but I over all like the Interface, good thing i don't have to install gerrit, last time i tried that it deleted my username on deinstaling it again xD

gerrit committed a patch related to this issue.
It has been pushed to "master":

https://git.libreoffice.org/core/commit/9804cb2f195451811eff8924d7997a3cbd6d679d

tdf#95662 Convert , to . for the min-width in the Lists only

It will be available in 7.2.0.

The patch should be included in the daily builds available at
https://dev-builds.libreoffice.org/daily/ in the next 24-48 hours. More
information about daily builds can be found at:
https://wiki.documentfoundation.org/Testing_Daily_Builds

Affected users are encouraged to test the fix and report feedback.

Hi Robert,
Before and after your commit I get 'min-width:NaNcm', do you know why ?

Hi Xisco,
First of all, I am not my dad, I am Roberts son, Gerrit. Secondly, the NaN (not a number) is propably a bug coming from deeper in the code, this fix just scratched the surface, I have not looked so deeply into where the numbers come from. I think it would be best to put that in a new Bugreport and provide a minimal example file to better understand where the faulty numbe could be coming from.
Greetings,
Gerrit

Hi Gerrit,
sorry for the confusion, won't happen again.
Could you please share the info from About LibreOffice dialog?

it's weird that I and buovjaga ( comment 6 ) get min-width:NaNcm and you get min-width:0,635cm

If that helps, I get NaNcm on every mention of the word "border-?-width", e. g.

border-bottom-width:NaNcm;
border-left-width:NaNcm;
border-top-width:NaNcm;

(This may explain why I don't get a bottom border in some paragraphs)

For the record, here without the patch/commit, I do *not* get NaN (Not a Number) with Locale: en-US (en_US.UTF-8). I get min-width:0.635cm; as expected.

Xisco: as you are able to repro the NaN thing, you could debug the XSL values a bit. I will explain what I did.

In the file filter/source/xslt/odf2xhtml/export/xhtml/body.xsl find the variable block

<xsl:variable name="listLevelTextIndent">

After the closing tag of the variable, insert

<xsl:message>
    listLevelTextIndent <xsl:copy-of select="-$listLevelTextIndent"/>
</xsl:message>

Then run

make filter

Now, when you export the ODT bug document to XHTML, it will print your debug message to your console!!

Further, you can experiment and use your imagination variously with the debug elements to try to find the root cause :)

Dear Gerrit Großkopf,
This bug has been in ASSIGNED status for more than 3 months without any
activity. Resetting it to NEW.
Please assign it back to yourself if you're still working on this.

There is only fixed a part of this report. There also appear "margin-left:1,27cm;". There must be something going wrong deeper in the code which sometimes sets the German decimal separator. Looks as if its not recognized as a number …

I now get "min-width:0cm" when exporting with LO 7.2 alpha1:

<span style="display:block;float:left;min-width:0cm;">•</span>

Seems this is getting worse.

At this moment I could only export with LO 7.1.5.2, open a text editor and remove 
:0, with :0.
:1, with :1.

With LO 7.2.5.2 and newer versions I can't get a tab between bullet and following text. Bullet will disappear inside the text. Seems we have to revert to the old behavior…

Have had this trouble every time I have updated the German Base Handbuch, so I didn't test it before.

I am not seeing any visual difference with the bullet.

The change is seen in the style, where the min-width for the bullet span used to be 0.635cm and is now 0cm.

I bisected the change with the help of the command line conversion:

instdir/program/soffice --convert-to "html:XHTML Writer File:UTF8" --outdir ~/libobugs ~/libobugs/decimalseparator_xhtml.odt

The changing commit is
https://git.libreoffice.org/core/commit/9d3b39cf9fed9a305ac23d1ecaaafc8f7caaeeb0
HTML XSLT: Missing paragraph BORDER of stand-alone border paragraph (@style:join-border problem)

However, I don't understand why the XHTML filter exports the bullet in such a silly way:

<span style="display:block;float:left;min-width:0cm;">•</span>

It manually inserts a bullet character! The HTML filter does not do this silliness.

Try the new attached documents. Original *.odt and export with LO 7.1.5.2 and also LO 7.4.0.2. Both exports will look the same. Now remove 
:0, with :0.
:1, with :1.
There won't be found :0, in the document exported with LO 7.4.0.2. The export doesn't change but the export with LO 7.1.5.2 will look right.

After replacing :0, with :0. and :1, with :1. it looks well in LO 7.1.5.2 - but not in LO 7.4.0.2

In Robert's ODT all XML uses correctly a dot '.' and not ',' therefore the ',' are added later and there are some possibilites of the culpit:

I would like to provide some guidance to narraow down the possibilites!

1. I have checked the latest XSLT filter and could not view any ',' being added.
By using his input document locally without LibreOffice (LO) the XSLT spreadsheet could be sorted out (for the latest sources).
We (Michael Stahl and I) have a little test enviornment for the OASIS ODF TC that runs on Linux for the ODF2HTML XSLT, see https://github.com/oasis-tcs/odf-tc - especially the readme at: https://github.com/oasis-tcs/odf-tc/#odf2html-transformation-not-yet-automated-regression-tests


2. Be aware that not the ODT but a single XML is being provided to the ODT XSLT stylesheets by LibreOffice. 
To check the final flat file format, add an XSLT filter using the IDENT (identicall) transformation: https://github.com/oasis-tcs/odf-tc/blob/master/src/test/resources/odf1.4/tools/ident.xsl
for instance using the fodt suffix
as import/export filter, by this simply save to fodt format :-)
NOTE: We added some QA guidance on how to add a stand-lone LO office, Configuration and pretty printing for ODF file XML in the ODF TC docu:
https://github.com/oasis-tcs/odf-tc/#odf-editing-tool (just use the office you like)

3. Most likely the XSLT processor adds some localizied decimal-separator.
Those who have the problem might want to install the XSLT 2.0 extension (see above docu as well that uses Saxon processor instead - but do not forget to fill thbe check-box using XSLT 2.0 at the XSLT filter configuration).


Last but not least, I had been started writing this XSLT filter in my junior days early 2000 where HTML 4.0 was not fully implemented by browsers. When I look at the ODF of the test document using https://docs.oasis-open.org/office/OpenDocument/v1.3/os/part3-schema/OpenDocument-v1.3-os-part3-schema.html#property-text_list-level-position-and-space-mode
I realized that nowadays CSS text-indent might be used: https://caniuse.com/?search=text-indent
Helpful and efficient is to get into inspect mode (mouse context on selected HTML or press F12 on keyboard) and alter the HTML/CSS to watch if this might work.
I consider doing some hack-fest on HTML XSLT at our next LibreOffice Conference in Bucharest, fixing the given test document.. :-)
Sorry, close to no spare pro-bono time ahead (already quite booked).. ;-)

I would appreciate if someone could enhance the test document having multiple list levels and all possible features with different numbers for testing:
https://docs.oasis-open.org/office/OpenDocument/v1.3/os/part3-schema/OpenDocument-v1.3-os-part3-schema.html#property-text_list-level-position-and-space-mode

Created an external issue that might be mapped later to bugzilla:
https://github.com/oasis-tcs/odf-tc/pull/50

Created attachment 187815 [details]
Test document with different bullets an different levels.

Result for the test document is unusable together with LO 7.4.7, because min-width is set to '0' - see https://bugs.documentfoundation.org/attachment.cgi?id=181862&action=edit

With LO 7.1.5.2 you could repair the first level, but other levels will appear like the first level, don't will get more indent as it looks in *.odt-file.
