Christian,
I agree with your reading of the documentation of createPrettyPrint. However, it
was doing *more* than what it said it was doing.
Here's my element (for example):
<sensors>
BlueSensors
</sensors>
createPrettyPrint *should* produce (according to the documentation):
<sensors>BlueSensors</sensors>
but instead, I get:
<sensors/>
createPrettyPrint stripped my content, and the documentation clearly states that
it should not do that, and I don't believe that is what was intended. It does
this for elements that have embedded newlines. createPrettyPrint works fine if
the whitespace is only spaces, for example:
<sensors> BlueSensor </sensor>
So maybe my definition of whitespace was incorrect? From the XML Schema Part 2:
Datatypes W3C Recommendation 02 May 2001(partial):
"4.3.6 whiteSpace
[Definition:] whiteSpace constrains the ·value space· of types
·derived· from string such that the
various behaviors specified in Attribute Value Normalization in [XML 1.0
(Second Edition)] are
realized. The value of whiteSpace must be one of {preserve, replace,
collapse}.
preserve
No normalization is done, the value is not changed (this is the
behavior required by [XML 1.0
(Second Edition)] for element content)
replace
All occurrences of #x9 (tab), #xA (line feed) and #xD (carriage
return) are replaced with #x20
(space)
collapse
After the processing implied by replace, contiguous sequences of
#x20's are collapsed to a
single #x20, and leading and trailing #x20's are removed. "
I assumed createPrettyPrint would be *collapsing* as defined. However, this may
all be moot, as I recalled an earlier email regarding a possible bug in
XMLWriter, so that when I retrieved the latest daily build my problem went away!
I apologize for speaking too soon.
thanx
steve
