Use SQL Server 2005 XML APIs to normalize an XML fragment -

-

i have (untyped) xml being stored in sql server 2005 need transform normalized structure. structure of document looks so:

<wrapper>  <parent />  <node />  <node />  <node />   <parent />  <node />  <node />  <node /> <wrapper>

i want transform this:

<wrapper>  <parent>   <node />   <node />   <node />  </parent>  <parent>   <node />   <node />   <node />  </parent> <wrapper>

i can select xml out relational structure if need to, put problem there no attributes linking parent , child nodes together, order becomes issue when using set-based operations. how can use .nodes()/.value()/other sql server xml apis transform data? transformation needs run part of batch sql script extracting tool/language not reasonable option me.

actually - following code works (grouping here may isn't optimal, anyway):

declare @xml xml = '     <wrapper>      <parent id="1" />      <node id="1" />      <node id="2" />      <node id="3" />       <parent id="2" />      <node id="4" />      <node id="5" />      <node id="6" />     </wrapper>  '  ;with px (     select row_number() on (order (select 1)) rownumber         ,t.v.value('@id', 'int') id         ,t.v.value('local-name(.)', 'nvarchar(max)') tagname     @xml.nodes('//wrapper/*') t(v) ) select p.id [@id],     (         select n.id id         px n         n.tagname = 'node'             , n.rownumber > p.rownumber             , not exists             (                 select null                 px np                 np.tagname = 'parent'                     , np.rownumber > p.rownumber                     , np.rownumber < n.rownumber             )         order n.rownumber         xml raw('node'), type     ) px p p.tagname = 'parent' order p.rownumber xml path('parent'), root('wrapper')

but don't recommend use it. see here: http://msdn.microsoft.com/en-us/library/ms172038%28v=sql.90%29.aspx:

in sqlxml 4.0, document order not determined
i'm not sure can rely on order of tags inside wrapper (and code above more fun practical use).

actionscript 3 - TweenLite does not work with object -

-
i got following problem: i have object called tempscore game. this object blitted canvas renderer via copypixels method. object not display object. it's score-object (self made). score-object extends object called basicblitarrayobject. basicblitarrayobject extends eventdispatcher (therefore no display object). i tried apply several different tweenlite-plugins tempscore-object (i.e. transformaroundcenter, colormatrixfilter, etc.). nothing happens. absolutely nothing. sometimes error messages (when plugin requires display object , object not display object). far good. according greensock (maker of tweenlite) engine can tween numeric property of object. when plugin transformaroundcenter requires display object tweening have modify plugin working non-display object (tempscore). can't because it's way hard me. my game rests upon code: http://www.8bitrocket.com/book/ch11_blastermines.zip try apply tweenlite object called tempmine inside game class blastermines. ...
