Using txtadd with multiple text parameters in "for" loop

first try instead of:

set(media_list,'');

set(media_list, );

Hi,

here an example that should explain how the txtadd() action works:when using this is the code:
txtadd(destination, txt1, txt2, txt3);

it means that:
destination = txt1 + txt2 + txt3

the txt1 and txt2 and txt3 will be connected, added together and then saved into the destination variable,

that means further, when you want to add text to destination variable itself, you need to use the content of the destination variable as parameter,

e.g. to add additional text to the destination variable :
txtadd(destination, get(destination), txt2, txt3);

in your case this would be:
txtadd(media_list, get(media_list), get(i));
txtadd(media_list, get(media_list), '. ');
txtadd(media_list, get(media_list), get(skin_media_list[get(i)].name));
txtadd(media_list, get(media_list), '<br />');

Best regards,

this construction in not work ((( :
for examle %1=1 (and <data name="question1" answered="0">'test question'</data>)

txtadd(question_nm, 'data:question', %1);
txtadd(question_nm, get(question_nm), 'aaaa', 'bbb');

set(layer['question_text'].html, get(question_nm)); - is not work((

i have data:question1aaaabbb instead "test questionaaaabbbbb"

what am I doing wrong? thank!

if %1 is "1" :
txtadd(question_nm, get(data[calc("question" + "%1")].content), 'aaaa', 'bbb');
txtadd(question_nm, get(data[question%1].content), 'aaaa', 'bbb'); // maybe works, too

if %1 is "question1" :
txtadd(question_nm, get(data[%1].content), 'aaaa', 'bbb');

documentation :
https://krpano.com/docu/xml/#data

perhaps like this works too.
untested.

calc(question_nm, data[question%1].content + 'aaaa' + 'bbb');

or

calc(question_nm, data[%1].content + 'aaaa' + 'bbb');

solved! )
txtadd(question_ans, 'data[question', %1,'_ans',get(i),'].content');

...and new problem((

I have array:
currq_array[1].value='test value1'
currq_array[2].value='test value2'
...
this expression:
1) trace('test value=',get(currq_array[get(i)].value)); - returns a correct "test value1", "test value2"...
and
2) txtadd(newtext, get(currq_array[get(i)].value));
set(layer['question_text'].html, get(newtext));
returns to layer "data.content"

the mind does not understand why so ???

help who knows please!

txtadd(a, get(b));
makes no sense, you're not adding anything :)

for this you could simply use
copy(a, b);

also this
txtadd(newtext, get(currq_array[get(i)].value));
set(layer['question_text'].html, get(newtext));
is too complicated.

the same is done much easier with
copy(layer[question_text].html, currq_array[get(i)].value);

many thanks! You helped me a lot!
now it works !!
SOLVED!
Result:
copy(tmp, get(currq_array[get(i)].value));
txtadd(newtext, get(tmp));
