xslt - How can i format XML to desired XML -


i have xml below. tried xsl code transform desired output. not successful. grouping , selecting specific nodes hard tag 'a''s values constant.they can 'math'and 'phys' (except class name). have group these values class name.

input: 

<sheet>    <row>       <a>class:x</a>     </row>     <row>       <a>math</a>       <e>10</e>     </row>     <row>       <a>phys</a>       <e>14</e>     </row>       <row>       <a>class:y</a>     </row>       <row>       <a>math</a>        <e>8</e>       </row>       <row>        <a>phys</a>        <e>12</e>       </row>     </sheet>

desired output:

 <sheet>     <row>       <class_type>x</class_type>       <math>10>/math>        <phys>14>/phys>      </row>      <row>       <class_type>x</class_type>       <math>8>/math>        <phys>12>/phys>      </row> </sheet>

my attempt:

<xsl:template match="/">     <xsl:apply-templates select="/s0:root"/> </xsl:template> <xsl:template match="/s0:root">     <ns0:sheet>                 <xsl:for-each select="s0:row">                     <xsl:if test="contains(s0:a/text(),'class:')">                         <ns0:class_type>                             <xsl:value-of select="substring-after(s0:a/text(),'class:')"/>                         </ns0:class_type>                     </xsl:if>                     <xsl:if test="contains(s0:a/text(),'math')">                         <ns0:math>                             <xsl:value-of select="s0:e/text()"/>                         </ns0:math>                     </xsl:if>                     <xsl:if test="contains(s0:a/text(),'phys')">                         <ns0:phys>                             <xsl:value-of select="s0:e/text()"/>                         </ns0:phys>                     </xsl:if>                 </xsl:for-each>     </ns0:sheet> </xsl:template>

here's 1 way @ this:

xslt 1.0 

<xsl:stylesheet version="1.0"  xmlns:xsl="http://www.w3.org/1999/xsl/transform"> <xsl:output method="xml" version="1.0" encoding="utf-8" indent="yes"/>  <xsl:template match="/sheet">     <xsl:copy>         <xsl:for-each select="row[contains(a, 'class:')]">             <row>                 <class_type>                     <xsl:value-of select="substring-after(a, 'class:')"/>                 </class_type>                 <math>                     <xsl:value-of select="following-sibling::row[a='math'][1]/e"/>                 </math>                  <phys>                     <xsl:value-of select="following-sibling::row[a='phys'][1]/e"/>                 </phys>              </row>         </xsl:for-each>     </xsl:copy> </xsl:template>  </xsl:stylesheet>

this assuming every "class" row has "math" , "physics" rows following before next "class" row comes along.

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj...

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer ...
