How do I know the current repeat number?

[Koen]

Hi,

I am sure this has been asked before, but I can't seem to find it, possibly
because I do not know the correct words to describe the issue. I have been
using CSPro, in which this would be described as an occurence number.

Anyway: I am setting up a household questionnaire, which includes a
household roster. Before the household questionnaire I have added twenty
questions that ask for the name of each household member (I will do the
survey in Africa, 20 member households exist). I can refer to these names
later in later questions, which is great. Instead of asking for the
household member id I can just display the name. However, I would like to
be able to refer to these names from within the household roster. For
example: "How old is ${hh_member_nm_1}?" For this to work I would have to
know what occurence of the household roster I am in. After that, I would
still need to find a way to properly refer to the proper name:
hh_member_nm_1 the first time etc, but could just code 20 notes with a
relevance set to just one household member, so that'll work just fine.

Any ideas? If all else fails we could just use little pen and paper
notebooks to keep track of this, but the whole point was to eliminate
paper!

Thanks!
Koen

P.S. The whole thing with the 20 names I just came up with because it seems
I can not refer to hh_roster_name[1] in answer list, while I can easily
refer to answer values like ${hh_member_nm_1}. If this is mistaken, then my
whole problem would also just disappear.

Within XPath expressions, position() sort-of gives you the repeat position
of the current record (this acts like @position, but that doesn't work in
javarosa). Read up on XPath expressions to understand how position()
differs from the repeat index (i.e., due to filtering).

Often, you can use relative references to get at values that you need, so
you often don't need to know the index of the item you're on.

It may also be that the tools available ( Build / XLSForm ) do not give you
the ability to express what you want. The underlying XForms are more
powerful, but far more difficult to work with.

Hi Mitch,

Thanks for your help. To be honest I have (virtually) no idea what I'm
doing within the XML file: I use XLSForm.

I've tried the following things;
To report the current position I have included a calculate in the repeat
group: position()
This doesn't quite work; it never gives me an error, but just reports 1 for
every occurence (repeat index?). Not sure why.

Then I tried to extract some info from the repeat group. This could be
useful for a number of things. Hasn't worked. This is mostly because
XLSForm tries to translate things to xpath for me I think. If I do
something of the sort:

/household_rostrer[postion() = 1]/age

I will try toying around with xml when I get to work tomorrow, but if you
know more and are willing to share, thanks! The first thing is my main
problem I suppose. I can get around the second issue by not including any
things I want to refer to later in repeats. (I am currently using it for
names only, and prefer to record them first anyway.)

Dear friends,

I want explore some advance features in xlsform for odk collect. just now I
read this post and found this is very interesting. I have a query regarding
this. For example, in a repeat group I asked a person, personal details
like name, sex, age etc for each family members in his family, and after
exiting the repeat group i want to ask some more information to some of the
family member. I want to create a select_one field having all the name of
that family members, how do I do this. request you to give an idea, I tried
the file try.xls (attached in the previous post) ,but it's not showing the
name in the field.

Many thanks in advance.

I tried this a while back and don't think this is possible with position().
You'll probably need the preceding-sibling:: XPath axis for that (e.g.* **
count(../preceding-sibling::child)* ), which I believe is not supported in
the ODK libraries. It does work in enketo http://enketo.org/formtesterbut since it does not pass ODK Validate you'd have to somehow bypass this
(and no idea if that would cause other issues).

If you do find a way, please report back!

Attached is a form with an example of using max() across a set of values
stored in a repeat group.

To get a list of names for display from a field within a repeat group, you
could use join(', ', ${fieldname) or concat(${fieldname}) instead of
something like max() or min().

I concur with Martijn. position() doesn't work with ODK Collect.

If you search a post I made on the same subject some time back, someone
pointed me to an issue with javarosa, and why it's not currently supported.

First say, many thanks for responding.

It's very helpful to learn, but I am not very well with nodeset arguments,
can it possible to add a field instead of second repeat group, asking the
user to choose one person's name which earlier entered in the first repeat
group. For example

in the first repeat group, I capture information about three perseons
Name Age Sex
Abc 23 Male
Pqr 19 Female
Xyz 21 Male

At the end of the repeat group, next question should be "Please select the
respondent" with following option
Abc
Pqr
Xyz

Again thanks for your valuable time..

Okay seems clear that there is no elegant solution. I have decided my time
is better spent on other things.

I have now implemented the following, extremely ugly, workaround:

The only part of the household roster which I refer to a lot in the rest of
the survey is the names. These are now in 20 separate questions. (If one is
left empty, the rest is skipped). Using some also very ugly calculated
fields it counts the number of non-empty names, which is how many times the
household roster will be repeated.
The first question in the householdroster is now: "Please enter the number
in parentheses above", which yields the number I'm afer: the member id.
This is followed by 20 notes, each set to be relevant for only one member
id, which displays the name of that member: E.g. "Please answer the
following question for Koen".

This does all I want from it, it's just very ugly, and not flexible at all.
So it's hard to extend the idea to other rosters that I might include
later. It also opens the door for user error in typing the member id code:
but with extra training and supervision that should remain manageable.

Fortunately Excel can automate the generation of names and relevance codes
etc., so it's actually not too much work using XLSForm.

Hi Koen,
Can you share the xls / xml of your solution. I am trying to achieve
something similar to you and at the end of the day, I guess it only matters
if it works !

Yes. See this explanation of XPath expressions:

Hopefully that will clarify how to create what you want.

Hi,

We decided not to use a repeat group for the household roster at all.
Instead, I made 20 copies of all questions. For this to be possible, I made
sure that things are numbered using references to one cell that contains
the repeat count. Unfortunately, most of this got lost in translation
somewhere where I had to paste values to a new excel file, but basically
instead of hardcoding hh_gender_1 for member 1's gender, you write in excel
="hh_gender_"&B23, where B23 is the cell where you write the repeat number.

To use skips you wirte something like ="${"&B44&"}='1'" in the "relevant
column, where B44 would be the cell containing the name of the variable on
which the relevance depends.

I used the same mechanics to create a flexible numbering scheme, in two
helper columns.

This way, you can just make sure your questions work, and if they do,
copy-paste them twenty times. You'll get a huge file, but it's the best I
could think of.

But I don't know if this can be expressed directly in XLSForm or if you
will need to hand-edit the form afterward to change an itemset expression

Thanks Koen
I shall give it a try as well. Meanwhile i came across another method as
well which i have documented in another of my posts in the group.

Hi,

We decided not to use a repeat group for the household roster at all.
Instead, I made 20 copies of all questions. For this to be possible, I made
sure that things are numbered using references to one cell that contains
the repeat count. Unfortunately, most of this got lost in translation
somewhere where I had to paste values to a new excel file, but basically
instead of hardcoding hh_gender_1 for member 1's gender, you write in excel
="hh_gender_"&B23, where B23 is the cell where you write the repeat number.

To use skips you wirte something like ="${"&B44&"}='1'" in the "relevant
column, where B44 would be the cell containing the name of the variable on
which the relevance depends.

I used the same mechanics to create a flexible numbering scheme, in two
helper columns.

This way, you can just make sure your questions work, and if they do,
copy-paste them twenty times. You'll get a huge file, but it's the best I
could think of.

Okay seems clear that there is no elegant solution. I have decided my
time is better spent on other things.

I have now implemented the following, extremely ugly, workaround:

The only part of the household roster which I refer to a lot in the rest
of the survey is the names. These are now in 20 separate questions. (If one
is left empty, the rest is skipped). Using some also very ugly calculated
fields it counts the number of non-empty names, which is how many times the
household roster will be repeated.
The first question in the householdroster is now: "Please enter the
number in parentheses above", which yields the number I'm afer: the member
id. This is followed by 20 notes, each set to be relevant for only one
member id, which displays the name of that member: E.g. "Please answer the
following question for Koen".

This does all I want from it, it's just very ugly, and not flexible at
all. So it's hard to extend the idea to other rosters that I might include
later. It also opens the door for user error in typing the member id code:
but with extra training and supervision that should remain manageable.

Fortunately Excel can automate the generation of names and relevance
codes etc., so it's actually not too much work using XLSForm.

I concur with Martijn. position() doesn't work with ODK Collect.

If you search a post I made on the same subject some time back, someone
pointed me to an issue with javarosa, and why it's not currently supported.

I tried this a while back and don't think this is possible with

is not supported in the ODK libraries. It does work in enketohttp://enketo.org/formtesterbut since it does not pass ODK Validate you'd have to somehow bypass this
(and no idea if that would cause other issues).

If you do find a way, please report back!

Hi Mitch,

Thanks for your help. To be honest I have (virtually) no idea what I'm
doing within the XML file: I use XLSForm.

I've tried the following things;
To report the current position I have included a calculate in the
repeat group: position()
This doesn't quite work; it never gives me an error, but just reports
1 for every occurence (repeat index?). Not sure why.

Then I tried to extract some info from the repeat group. This could be
useful for a number of things. Hasn't worked. This is mostly because
XLSForm tries to translate things to xpath for me I think. If I do
something of the sort:

/household_rostrer[postion() = 1]/age

I will try toying around with xml when I get to work tomorrow, but if
you know more and are willing to share, thanks! The first thing is my main
problem I suppose. I can get around the second issue by not including any
things I want to refer to later in repeats. (I am currently using it for
names only, and prefer to record them first anyway.)

Op woensdag 6 maart 2013 20:02:25 UTC+1 schreef Mitch het volgende:

Within XPath expressions, position() sort-of gives you the repeat
position of the current record (this acts like @position, but that doesn't
work in javarosa). Read up on XPath expressions to understand how
position() differs from the repeat index (i.e., due to filtering).

Often, you can use relative references to get at values that you need,
so you often don't need to know the index of the item you're on.

It may also be that the tools available ( Build / XLSForm ) do not
give you the ability to express what you want. The underlying XForms are
more powerful, but far more difficult to work with.

P.S. The whole thing with the 20 names I just came up with because it

then my whole problem would also just disappear.

Again thanks for the idea, I used indexed-repeat() and position() and it
resolved my query almost. But when I use dynamic repeat group (don't know
the number of repeat), I can not create the dynamic options for the
drop-down as I don't know how many repeats are there. Hope you will share
your knowledge to solve my query.

In the first repeat group, I capture information about # persons
Name Age Sex
Abc 23 Male
Pqr 19 Female
Xyz 21 Male
....
....
....

At the end of the repeat group, next question should be "Please select the
respondent" with following option
Abc
Pqr
Xyz
...
...
...

You will generally need to make an assumption as to the upper limit on the

of repeats.

I don't know of any solution that could work with an unlimited number.

(the 2.0 tools take a completely different approach and can support
something like this, but these are not yet released).

because it seems I can not refer to hh_roster_name[1] in answer list, while
I can easily refer to answer values like ${hh_member_nm_1}. If this is
mistaken, then my whole problem would also just disappear.
