Re: [basex-talk] file:write, formatting, and maps in select attributes

Hi Andy,

Those look like very useful links; thank you!

Absolutely not going to argue it's BaseX's job in particular to have a
considered-as-lines consistency default, but keep running into situations
where one is needed.

thanks!

 Hi Graydon,

>I'm trying to regularize the formatting of some XSLT files

I don't think this can or should be done with BaseX serialization. I would
use a dedicated formater/ pretty printer.
For me the sign of a good formatter  is that it tidies random indentation
while preserving what looks intentional.

Phil Fearon has done a lot of great work on formatting XML/XSLT [1]. I use
his Deltaxml Vscode extension [2]
Works for me [3]
If Vscode is not a route you want to take, maybe the older standalone
xmlspectrum [4] would also work (untested).

Re: [basex-talk] file:write, formatting, and maps in select attributes

Hi Graydon,

This might not be a serialization but a parsing problem  The XML parser 
performs attribute value normalization as per 
https://www.w3.org/TR/xml/#AVNormalize

I have often wished that there were a parser option to preserve newlines in 
attribute values, in particular for keeping the indentation of multiline XPath 
expressions in XProc or XSLT in a future XProc 1.0 → 3.0 migration tool.

For such a migration, the XPath expressions may need modifications, too, so I 
thought they need to be parsed and transformed anyway, and then they can be 
re-serialized with indentation (I haven't tried b/c I'm  writing this on the 
phone, but I strongly believe I can have newlines serialized in attribute 
values).

But in your case a parser option would be useful.

An alternative could  be to apply some text preprocessing to the document. For 
example, read it with unparsed-text, use analyze-string to match attribute 
values (difficult even in moderately complex cases), replace each newline with 
a PUA character and serialize this character as newline using a character map 
later on.

Subject: [basex-talk] file:write, formatting, and maps in select attributes

Hello --

I'm trying to regularize the formatting of some XSLT files by loading them
(via doc()) and writing them back out via file:write()

I know about the *indent* and *indent-attributes* serialization parameters,
and mostly they're doing what I want.

What I'd like is to preserve a one-line-per-entry format for a map in a
select attribute. For example, I'd like to keep



instead of



I don't think there's a way to do this with the serialization parameters,
but is there a way to do this?

Thanks!
Graydon
