[Xerte] Xerte Dynamic Templates tutorial - clarification

Thu Jul 16 11:51:35 BST 2009

I am sorry I did not make myself clear.

I understand that the reference to 'value'  was a variable and that
duplicate would result in duplication of the icon, what I was struggling
with was 

a) the apparent discrepancy between the code in the image which refers
to 

icon.nextSibling.childNodes[2]

and the code referred to in the accompanying text which refers to 

icon.nextSibling.firstChild 

b) trying to figure out what icon.nextSibling.childNodes[2] was actually
identifying in the document tree and why that was so.

Similarly I was struggling to figure out, by tracking back up the
document tree how it was that on page 11 in the pdf file (no page number
in the xerte help file, but it is in the section 5 create the template
logic section)

icon.ParentNode.index( ) -2          would return the number of
questions.

Also I was puzzled by the reference later in the same section to
quizData as I was not sure where this object had been defined.
Is it the case that since earlier we set templateDate to point to the
quiz.xml file that quizData is effectively the same as templateData?

I am trying not just to duplicate the actions in the tutorial but to
understand them, so that I can create my own templates.

Kind regards

the parameter just describes how many times you want to duplicate the
icon - don't run it twice!

(value) is just a variable, a number, for how many times you want to
duplicate the icon.

Subject: [Xerte] Xerte Dynamic Templates tutorial - clarification

 I am part way through the simple quiz example in the dynamic templates
tutorial as described in the document XerteDynamicTemplates.pdf

I am following through the example step by step and trying to ensure
that I understand the logic behind each step, so that I will then be
able to apply this to creating my own templates.

Can I seek clarification on the following points?

Page 10
The code uses icon.nextSibling.childNodes[2].duplicate(quesCount -1)
But the text refers to icon.nextSibling.firstChild.duplicate(value)

Is this a typing error? Are both statements required in the code?

Page 11
Why does icon.parentNode.index( ) - 2 = the number of questions?

Page 12
Where does the quizData object come from, there appears to be no
previous reference to it?

And a general question - is there a way of easily identifying which node
is being referenced at any time by an expression?
E.g. is there a way of echoing a value for
icon.nextSibling.firstChild.name or .value

I guess I am looking for any tricks you have picked up along the way
that aid you in debugging your template creation.

Kind regards
