fn:deep-normalize-space($e as node())

[michaelhkay]

Summary: removes redundant whitespace within the content of a given node, leaving the element structure intact.

Example:

 <p>  My <i>crazy</i>
<b> content</b>.
</p> 

becomes

<p>My <i>crazy</i> <b>content</b>.</p>
Rules (expressed informally, and may need refining):

• The string value of the result is the normalize-space() of the string-value of the input.
• Every non-whitespace character in the result has the same ancestor path as the corresponding character in the input (for example if it was in an i element in the input, then it will be in an i element in the output).
• When several adjacent whitespace characters from different elements in the input are combined into a single space in the output, the resulting space will be in a text node whose parent is the result node corresponding to the common ancestor of those different elements.

For example <i>easy </i><b> peasy</b> becomes <i>easy</i> <b>peasy</b>

Could perhaps also add an option to word-wrap to a given line length.

The Markdown rendering may be interfering with the presentation of the examples. For clarity's sake, could you please provide the examples in fenced code blocks? Here's my attempt at adapting the examples above - but please correct me if I'm wrong.

Also, would elements with @xml:space="preserve" be omitted from processing?

Lastly, word-wrap would be amazing!

Example 1

fn:deep-normalize-space(<p>
My <i>crazy</i>
<b>content</b>.
</p>)

returns:

<p>My <i>crazy</i> <b>content</b>.</p>

Example 2

fn:deep-normalize-space(<p><i>easy </i><b> peasy</b></p>)

returns:

<p><i>easy</i> <b>peasy</b></p>

Do we want to keep this function proposal open?

I did a quick attempt to implement it, but I think some more effort would need to spend to formalize the rules.

File it under "it seemed a good idea at the time".
