OpenXml Powertool HtmlConverter lists - extending functionality - openxml

I have been stepping through the OpenXml Powertool HtmlConverter class to understand how list bullets and numbers are retrieved and put into the html but I am a bit confused. All i want to do is add a custom attribute to the output span that include the numFmt (ie. <span data-numId='1' data-numFmt='decimal'>1.</span>) but this is proving to be morethan I thought.
What is the best way to do this?

To anyone interested, I managed to do this and I have made the code available on GithHub: https://github.com/leoseccia/Open-Xml-PowerTools

Is it possible to use data frame in r-exams?

I would like to paste the data-frame from the R environment to the latex part (question or solution part) when creating exercises in r-exams. Later the exercises will be imported into Moodle. Is that possible in r-exams? We saw it is possible when the object is matrix object via $\Sexpr{toLatex(matrix_obj)}$. But a similar way does not seem to work with the data-frames. Thank you!
A data.frame would usually be included as a {tabular} in LaTeX and there are various packages for automatic conversion like xtable or using the function kable() in knitr. For PDF output this also works nicely including all vertical and/or horizontal lines included in the table. However, for HTML-based output (as for Moodle) the table as such is converted correctly but without any lines.
An overview of a couple of solutions is available as:
Different copies of question with table for Moodle with R-Exams
Moreover, Kenji Sato has proposed to inject some dedicated CSS code to handle the table formatting in HTML. We are currently working on some automated way of including this in R/exams:

Labels formatting (via tags) in locallang.xlf

Whenever a part of a language label needs to be somehow highlighted, what is considered as best practice here?
I'm usually trying to avoid html tags in language labels as far as possible by splitting label into a parts and wrapping into corresponding tags in Fluid.
In worst case label is wrapped with CDATA:
<trans-unit id="my.label">
<source><![CDATA[Here comes a <strong>bold text</strong> and then <em>italic</em> and now <span class="fancy">fancy styled</span> stop]]></source>
</trans-unit>
But this mixes content and presentation, which can bring pain afterwards, when CSS is refactored and some classes are renamed.
Another solution, coming into my mind, is to move all the texts, that may contain html tags, out of XLF to either plugin's FlexForm RTE field or some configuration record with RTE fields. But it also looks rather like hack.
How do you solve such an issue usually?
For me there are some possible options, depending on the kind of text.
1.) Avoid HTML as much as possible
2.) If this HTML is wrapped around any arguments, move the HTML out and use it as argument for the <f:translate /> ViewHelper.
3.) Sometimes it is hard to use arguments as the translation is just different and I then use different partials/sections for the different languages and don't use any language file.
4.) I use the CDATA approach.
An addition to Georg Ringer's answer (whose point 1 is definitely the way to go, if at all possible):
5.) Use what XLIFF offers. XLIFF 1.2 has elements to mark tags inside translatable content - to be precise, it has too many such elements. One possible representation of your example would be
<trans-unit id="my.label">
<source>Here comes a <bpt id="1"><strong></bpt>bold text<ept id="1"></strong></ept> and then <bpt id="2"><em></bpt>italic<ept id="2"></em></ept> and now <bpt id="3"><span class="fancy"></bpt>fancy styled<ept id="3"><span></ept> stop</source>
</trans-unit>
This looks messy in code, but it has the advantage that an XLIFF aware translation editor will present this to your translators in a way that is easy for them to work with, like this:
.
The translator will be able to move these tags if the text order needs to be changed in the target language, and they can delete these purple tags in whole if they don't make sense in the target language: for example some complex Chinese characters look awful in bold face. They will not be able to delete parts of tags either.
One possible solution could be the use of parameters in the translation strings. Those parameters could be filled with translated strings which are wrapped in tags (by TS or fluid). This might result in a very complex translation handling as the strings are broken down to multiple strings (which might partially loose context).
Another solution could be the use of markers (like ###B### for <b>and ###_B### for </b>) for the tags which are replaced at the end (and which could vary for different devices). This also is complex and needs a good configuration and invents something like a further markup.

Drupal - dynamic options for text_list field

I have a custom node type for which I want to have a field that uses a special combobox based on list_text. When one chooses the type list_text it is normally possible to enter a static list of selectable texts, however, I want this list to be dynamic, i.e. based on the results of a db_query. What is the best way to do this using Drupal 7?
A simple example for clarification: A node of this custom type X contains a field that points to another node, so whenever a node of type X is created I want a combobox that contains all other nodes.
(Best solution would be to only display the combobox during node creation, and no longer during edit. But I could also live with it if the combobox was shown during the edit as well.)
I have tried to customize options_select by defining my own data type and implementing hook_options_list accordingly. The combobox was displayed during creation with the correct values, however, I could not save it.. I have no idea what went wrong there, but on the first submit it would change to a different theme, and when I tried again I got an internal server error. Am I on the right track at all with defining a completely new data type for the field? there surely must be a simpler way?
You're right in that you don't need a new datatype. Here's a good tutorial on how to do this. It's not specifically for D7 but I didn't see much that wasn't still applicable. There may be a better way to do it in D7 specifically but I would love to know it too if so :)
The tutorial linked by allegroconmolto sent me on the right way. Thanks for that.
Here's the simpler way of doing it: tutorial
Basically, it is, as I assumed, a common problem and hence a simple solution for it was included in the webform module by now. It provides a hook_webform_select_options_info which can be used to register a callback method. The callback method is then called each time a corresponding option select of a webform is shown, so that you can easily fill it with the results of a dbquery or anything else. Works like a charm and takes next to no time to implement.

Extracting function call list from DOxygen XML Output

I posted a question on the DOxygen forums and also am posting it here for a better response.
I have a moderately sized C project of about 2,900 functions. I am using DOxygen 1.5.9 and it is successfully generating a call graph for the functions. Is there a way to extract this out for further analysis? A simple paired list would be sufficient, e.g.
Caller,Callee
FunctionX, FunctionY
...
I am comfortable with XSLT but I must say that the DOxygen XML output is complex. Has anyone done this before and can provide some guidance on how to parse the XML files?
Thanks in advance!
Based on what I see in the contrived example that I created,
Parse files with a name similar to ^_(.+)\d+(c|cpp|h|hpp)\.xml$, if my regex-foo is right.
Find all <memberdef kind="function">. It has a unique id attribute. I believe the XPath for this is //memberdef[#kind='function'].
Within that element, find all <references>.
For each of those tags, the refid attribute uniquely refers to the id attribute of the corresponding <memberdef> that is being called.
The text node within each <references> corresponds to the <name> of the corresponding <memberdef> that is being called.
This seems like a nice, straightforward way to express call graphs. You should have no trouble using XSLT or any other sane XML-parsing suite to get the desired results.

Highlight some text in a Jasper Reports viewer

I want to highlight some parts of the reports i'm generating for display.
I don't want to change the report definition. I want to highlight the output at runtime.
But the JRViewer i'm using doesn't really have much of an API.
And manipulating the JasperPrint object with setForecolor/setBackcolor before displaying it, didn't seem to change the output.
Any ideas? Or do i have to overload/reimplement the viewer? Wouldn't be much of a problem since it's open source, but i'd like to prevent reinventing the wheel.
Looks like i have to answer my questions myself... again.
I overloaded the JRViewer class (actually copied the code of JRViewer because none of the interesting panels were accessible) and added some highlighting methods to do the following:
Template based JasperPrint data uses - like the name suggests - templates. Meaning the text objects don't have a style of their own, they use their template's style.
That is the reason why setForecolor didn't do anything - the JRTemplatePrintElement implementation is plain empty.
But if i would set the highlight on the text template i would end up with a full column of highlighted texts, since they share the template instance.
Instead i create a new template as a copy of the original with highlighting and use that in the highlighted print elements. Btw, those jasper elements could really use a clone() method.
Feels like a hack, but i don't see a better way.
UPDATE:
However this has a nasty sideeffect for file based (virtualized) reports.
These apparently save any changes you make to the elements while you walk the pages.
If however the viewer in the meantime causes the virtualizer to discard the elements you reference (for example by flipping pages), your further changes won't be saved...
So that made me reconsider and now i'm just drawing my highlighting on top of the Graphics object painted by Jasper's PageRenderer.
Much simpler and cleaner. Only highlighting the background won't work this way.
