[xsl] Re: sum

This is easy to do with FXSL.

Search the list for "transform-and-sum". There are several examples -- e.g.:

Hello, i have the following question,

Im dealing with the following xmlfile (only showing parts of it)


<GOPSIZE>
<GOP_BYTE>721619968</GOP_BYTE>
<GOP_BYTE>35392768</GOP_BYTE>
<GOP_BYTE>3214937088</GOP_BYTE>
<GOP_BYTE>2174815232</GOP_BYTE>
<GOP_BYTE>2650147328</GOP_BYTE>
<GOP_BYTE>1301153792</GOP_BYTE>
<GOP_BYTE>1162808064</GOP_BYTE>
</GOPSIZE>

<SUBSTR8>
    <SUBSTREAM>
                <lengthbit>0</lengthbit>
                <stuff>5</stuff>
<two>167</two>
                <SUBSTREAM_interior>477407 1447</SUBSTREAM_interior>
    </SUBSTREAM>
    <SUBSTREAM>
<lengthbit>0</lengthbit>
<stuff>18</stuff>
<two>83</two>
<SUBSTREAM_interior>478856 4691</SUBSTREAM_interior>
    </SUBSTREAM>
    <SUBSTREAM>
<lengthbit>0</lengthbit>
<stuff>58</stuff>
<two>46</two>
<SUBSTREAM_interior>483549 14894</SUBSTREAM_interior>
    </SUBSTREAM>
    <SUBSTREAM>
<lengthbit>1</lengthbit>
<stuff>0</stuff>
<four>60422</four>
<SUBSTREAM_interior>498447 60422</SUBSTREAM_interior>
     </SUBSTREAM>
     <SUBSTREAM>
<lengthbit>1</lengthbit>
                <stuff>0</stuff>
<four>233080</four>
<SUBSTREAM_interior>558873 233080</SUBSTREAM_interior>
      </SUBSTREAM>


what i would like to do is take the sum of all the rightparts of the
<SUBSTREAM_interior> elements and substract this from the first <GOP_BYTE>
element. 2 problems arise here, first of all,
how can i take a sum of those elements?

I use number((substring-after(normalize-space(m:SUBSTREAM_interior),' ')))
to reach the right part of the <SUBSTREAM_interior> but something like

<xsl:template name="substream8" match="m:SUBSTR8">
      <xsl:value-of
select="sum(number((substring-after(normalize-space(./m:SUBSTREAM/m:SUBSTREA
M_interior),'
'))))"/>
</xsl:template>

doesnt work,

and secondly when i got the sum how can i substract it from a
<GOP_BYTE>element wich is standing higher in the xmlfile then the <SUBSTR8>
?

I hope someone can help me out here,

greetings Chris
