exslt - Best approach for combining several XSLT 1.0 passes which process the same nodes -

-

i'm doing complex xslt 1.0 transformation (currently using 8 xslt passes). want combine 8 passes without merging them in 1 file (this complex). solution using xsl:include , exsl:node-set merge passes , store temporary results in variables.

but have 1 problem: transformation passes copies of nodes , modifying aspects. therefore need process same nodes in every pass, different xsl:template! how do that? how tell after first pass want apply templates other xslt stylesheet?

very simplified example i'm doing (2 xslt passes):

source:

<h>something here</h>

after xslt pass 1:

<h someattribute="1">something here</h>

after xslt pass 2:

<h someattribute="1" somemoreattribute="2">something here, , more</h>

my current approach call xslt processor twice , saving results temporary on disk:

xsltproc stylesheet1.xsl input.xml >temp.xml xsltproc stylesheet2.xsl temp.xml >finalresult.xml

one possible solution change each of stylesheets use distinct mode. import them master stylesheet , multiple passes applying templates using each mode in turn:

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/xsl/transform"                 xmlns:exsl="http://exslt.org/common"                 extension-element-prefixes="exsl"                 version="1.0">    <xsl:import href="stylesheet1.xsl"/> <!-- assuming mode="stylesheet1" -->   <xsl:import href="stylesheet2.xsl"/> <!-- assuming mode="stylesheet2" -->   <xsl:import href="stylesheet3.xsl"/> <!-- assuming mode="stylesheet3" -->    <xsl:template match="/">     <xsl:variable name="temp1">       <xsl:apply-templates select="." mode="stylesheet1"/>     </xsl:variable>     <xsl:variable name="temp2">       <xsl:apply-templates mode="stylesheet2" select="exsl:node-set($temp1)"/>     </xsl:variable>     <xsl:apply-templates mode="stylesheet3" select="exsl:node-set($temp2)"/>   </xsl:template>  </xsl:stylesheet>

the downside need modify original stylesheets, adding appropriate mode attributes each xsl:templateand xsl:apply-templates. can still make stylesheets work independently adding template in each of them:

<xsl:template match="/">   <xsl:apply-templates select="." mode="stylesheet1"/> </xsl:template>

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. ...
