[scala-bts] #1767: XML parse error reporting cascades too far

#1767: XML parse error reporting cascades too far
----------------------+-----------------------------------------------------
Reporter:  extempore  |       Owner:  scala-xml_team
    Type:  defect     |      Status:  new           
Priority:  normal     |   Component:  XML support

----------------------+-----------------------------------------------------
 I am about to close a bunch of tickets related to the asserts in
 NewScanners which I changed in r17241 to regular parse errors: #822,
 #1674, #1682, and #1765.  I'm opening this ticket because some of those
 cases, now that they aren't crashers, receive a number of unhelpful error
 messages after the first.  I propose XML team investigate trimming the
 error reporting down to the last reasonably sensible message.

 cascading.

[scala-bts] #1773: XML strange equals behaviour

#1773: XML strange equals behaviour

-------------------------+--------------------------------------------------
 There is something wrong with the equals or with the XML processing stuff.
 Look at this:
 {{{
 scala> <a></a>
 res0: scala.xml.Elem = <a></a>

 scala> <a>{xml.NodeSeq.Empty}</a>
 res1: scala.xml.Elem = <a></a>

 scala> <a>{""}</a>
 res2: scala.xml.Elem = <a></a>

 scala> <a>{if (true) "" else "noo"}</a>
 res3: scala.xml.Elem = <a></a>

 scala> res0 == res1
 res4: Boolean = true

 scala> res0 == res2
 res5: Boolean = true

 scala> res0 == res3
 res6: Boolean = false

 I fixed the original issue. Reassigning to the XML team now. Please have a
 look at the spec and whether it's up to date with the parser.

Comment(by Alefas):

 Ok. this fix is clear for me, but not right at all. Braces was neccessary,
 so it should be ScalaExpr = '{' Block '}'.
 And I'm not trainspotter:)

 It looks inconsistent when values inside the xml elements are implicitly
 converted to string but values in the xml attributes are not.

 Reproducing:
 {{{
 scala> <x>{2+2}</x>

 res2: scala.xml.Elem = <x>4</x>

 scala> <x y={2+2} />

 <console>:5: error: overloaded method constructor UnprefixedAttribute

Comment:

 The given example works since 2.7.1.  This is strange to me, because I
 could swear I've tried it since then and it didn't work (and 2.7.2RC4 is
 mentioned above, which would imply it wasn't working in 2.7.1) but that is
 the situation.  I'm closing this as fixed unless someone would like to
 offer an example which doesn't work.
