xml - How to calculate sum of nodes, with different number format in xsl? -

-

i have following xml structure:

  <example>     <data>        <numberger>3,40</numberger>     </data>     <data>       <numberger>7,40</numberger>     </data>     <data>        <numberger>17,40</numberger>     </data>   </example>

i need sum of "numberger" nodes. formatting of number problem. because of use of "," function "sum" produces error. sum(//numberger) not work. can use xslt 2.0 functions.

i think need write recursive template, takes computed value , list of nodes.

something like:

<xsl:template name="addgernumbers">         <xsl:param name="number"/>         <xsl:param name="nodes"/>       <xsl:choose>         <xsl:when test="$nodes">           <xsl:variable name="recursive_result">             ...            <xsl:call-template name="addgernumbers">              ...             </xsl:call-template>             </xsl:variable>           <xsl:value-of select="$number + $recursive_result"/>         </xsl:when>         <xsl:otherwise>           <xsl:value-of select="0"/>         </xsl:otherwise>       </xsl:choose>     </xsl:template>

at end need single value result.

how xpath sum() previous nodes in xsl for-each loop? not work me, because need single number @ end.

a single xpath 2.0 expression enough:

<xsl:value-of select="sum( $i in //numberger return number(translate( $i, ',','.') ) )"/>

the for loop translate each value replace commas dots, convert them numbers. returns sequence of numbers can sum normally.

here (probably) simple problem: i'm trying use perceptual hashing library phash ubuntu 11.10. had ffmpeg installed, way i've done: sudo apt-get install libphash0 sudo apt-get install libphash0-dev then tried compile program: #include <iostream> #include <phash.h> using namespace std; int main() { ulong64 myhash=0; ph_dct_imagehash("test.jpg", myhash); cout<<myhash<<endl; } when compiling, prints out: undefined reference `ph_dct_imagehash' any suggestion? should do? in advance! matteo monti you forgot link phash library, linker cannot find function. try adding -l phash gcc command line (or update makefile). if doesn't work, maybe you'll need specify library path (the location of *.a file) using -l "/usr/lib/"
