Hi all!
I have a few XML documents, whose content I would also like to provide in JSON. The XML files contain many strings encoded within comments, such as <!--incipit—>, and I would like to transfer such string contents unchanged into JSON. However, I am having a hard time to deal with “-” ( using data(<!---—>) ), which is rendered as “&45;” , and “>”, which is translated into “>”: I tried a lot, but nothing seems to work: is there a way to keep “-” and “>” unchanged while serializing to JSON?
Another issue I am experiencing is that, after JSON serialization, the order of the key-values in a map does not follow that specified in my code: I know that the order is not computationally meaningful, but for reading purposes it would make a huge difference in my case, because one key contains a long array of objects and therefore I would like the keys with shorter contents to be serialized before.
Ciao, Giuseppe
Hi Giuseppe,
However, I am having a hard time to deal with “-” ( using
data(<!---—>) ), which is rendered as “&45;” , and “>”, which is translated into “>”: I tried a lot, but nothing seems to work: is there a way to keep “-” and “>” unchanged while serializing to JSON?
Could you provide us with a little self-contained example?

That's correct. If you want the order to be preserved, you’ll need to choose an XML representation for your JSON data.

Hi Christian,
I have the comment node <!—-—>. If I extract its content with data() in an element, I get the following: <g>&#45;</g>, and it seems there is no way to force &#45; to become - within the element: I found a workaround to replace &#45; with a dash '-', and this seems the best solution at the moment. My problem is that I have to refer to the positions of these characters (as character offsets), and therefore any change when I move a character from a comment node to an element node could break my reference system (indeed, &#45; is not equivalent to - in BaseX: is the rendering of - as &#45; correct?).
Ciao, Giuseppe

Hi Giuseppe,
I’m sorry, I fail to understand how to simulate your use case. Could you please provide us with a minimized code snippet for testing?
I have the comment node <!—-—>.
I assume it’s -- instead of —?
If I extract its content with data() in an element, I get the following: <g>&#45;</g>, and it seems there is no way to force &#45; to become - within the element.
I tried this:
let $comment := <!-- - --> return element g { $comment }
It gives me <g><!-- - --></g>. I assume it differs from your approach?
Grazie in anticipo, Christian
Hi Christian,
This is the code:
<h>{data(<!----->)}</h>

Hi Giuseppe,
<h>{ data(<!----->) }</h>
The literal string value of the comment is "-" (the codepoints are 38 35 52 53 59). You can use parse-xml-fragment() to decode character and entity references:
parse-xml-fragment(<!----->)
Hope this helps, Christian
