xslt - delete consecutive nodes with same name -


i trying use xslt transform following xml:

 <level>     <nextlevel>         <note> text text text </note>     </nextlevel>     <nextlevel>          <abc>         </abc>         <note>bla bla bla </note>         <note>bla bla bla bla bla</note>         <xyz>         </xyz>     </nextlevel>     <nextlevel>         <note> text text text </note>     </nextlevel> </level>

i want remove duplicate nodes "note" when appears twice consecutively. output should like:

<level>  <nextlevel>     <note> text text text </note>  </nextlevel>   <nextlevel>        <abc>     </abc>     <xyz>     </xyz>  </nextlevel>  <nextlevel>     <note> text text text </note>  </nextlevel> </level>

i using following xslt: 

<xsl:key name="dup" match="note" use="concat(generate-id(..), '|', name())"/>  <xsl:template match="@*|node()">     <xsl:copy>         <xsl:apply-templates select="@*|node()"/>     </xsl:copy> </xsl:template>  <xsl:template match="note[not(generate-id() = generate-id(key('dup', concat(generate-id(..), '|', .))[1]))]"/>

however, nodes name "note" being deleted, wrong xslt?

try using avoid repetition of consecutive node of same name same value 

 <xsl:template match="@*|node()">         <xsl:copy>             <xsl:apply-templates select="@*|node()"/>         </xsl:copy>     </xsl:template>          <xsl:template match="*[not(*)][name() = preceding-sibling::*[1]/name()][@value = preceding-sibling::*[1]/@value]" />

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds ...
