[XSL] non estrae valori da XML

[kob4yashi]

ho un foglio di stile che dovrebbe estrarre dei valori da un file XML di origine e riscriverli in un nuovo schema XML.
Il problema è che lo schema viene scritto ma non vengono riportati i valori che intendo visualizzare.

XML in input

<?xml version='1.0' encoding='ISO-8859-1' ?>
<?xml-stylesheet type="text/xsl" href="t_contourshape.xsl"?>
<Mpeg7><DescriptionUnit><Descriptor><Region><RegionNumber>255</RegionNumber>
<GlobalCurvature>7  3 </GlobalCurvature>
<PrototypeCurvature>1  3 </PrototypeCurvature>
<HighestPeakY>15</HighestPeakY>
<Peak peakX = "58" peakY = "5"/>
<Peak peakX = "5" peakY = "7"/>
<Peak peakX = "59" peakY = "1"/>
<Peak peakX = "61" peakY = "6"/>
<Peak peakX = "4" peakY = "6"/>
<Peak peakX = "2" peakY = "6"/>
<Peak peakX = "1" peakY = "7"/>
</Region>
</Descriptor>
</DescriptionUnit>
</Mpeg7>

ciao.
siccome nel tuo xml non ci sono i namespace .. se passi all xslt di cercare tst:blabla non lo trova ovviamente ..
ho tolto i tst: da davanti gli elementi sul tuo xslt e funziona .....
