Design Template XSLT to generate XML

i need to generate this xml with all things, namespaces on each node etc

<bdo_fosfec:RegistrosPagosElement xsi:type="bdo_fosfec:RegistrosPagos" 
 xmlns:bdo_fosfec="http://asocajas.app.com/example" 
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
 <registro54 xsi:type="bdo_fosfec:Registro54">
   <registro82 xsi:type="bdo_fosfec:Registro82">
     <C512>39756656</C512>
     <C614>YAXMINNI</C614>
   </registro82>
 </registro54>
 <registro54 xsi:type="bdo_fosfec:Registro54">
   <registro82 xsi:type="bdo_fosfec:Registro82">
     <C512>79374740</C512>
     <C614>VICTOR</C614>
   </registro82>
 </registro54>
</bdo_fosfec:RegistrosPagosElement>

And i build a this XSLT

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" indent="yes"/>
 <xsl:template match="/">
   <bdo_fosfec:RegistrosPagosElement xsi:type="bdo_fosfec:RegistrosPagos" xmlns:bdo_fosfec="http://asocajas.app.com/example" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
        <xsl:apply-templates select="registro54"/>
   </bdo_fosfec:RegistrosPagosElement>
 </xsl:template>
 <!--TEMPLATE REGISTRO 54-->
 <xsl:template match="registro54">
   <registro54 xsi:type="bdo_fosfec:Registro54">
        <registro82 xsi:type="bdo_fosfec:Registro82">
          <C512><xsl:value-of select="C512"/></C512>
          <C614><xsl:value-of select="C614"/></C614>
        </registro82>
   </registro54>
 </xsl:template>
</xsl:stylesheet>

but when i transform myxml with the XSLT the result xml is not as expected

result: 

 <?xml version="1.0" encoding="utf-8"?>
   <bdo_fosfec:RegistrosPagosElement xsi:type="bdo_fosfec:RegistrosPagos" xmlns:bdo_fosfec="http://asocajas.app.com/example" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" />

myxml

 <?xml version="1.0" encoding="utf-8"?>
  <bdo_fosfec_x003A_RegistrosPagosElement xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
    <registro54>
     <registro82>
      <C512>123456789</C512>
      <C614>Miguel</C614>
     </registro82>
    </registro54>
    <registro54>
     <registro82>
      <C512>1234567890</C512>
      <C614>Jerónimo</C614>
     </registro82>
    </registro54>
  </bdo_fosfec_x003A_RegistrosPagosElement>

I do not know what I'm doing wrong, I've tried removing the nameSpace xmlns: xsi = "http://www.w3.org/2001/XMLSchema-instance" xsi: type = "bdo_fosfec: RegistersPages" xmlns: bdo_fosfec = "http: //asocajas.hp.com/bdo_fosfec "of the stylesheet but it generates error, I also tried not to use" templates "and the result approaches the desired one but it is not the same that I hope

Thnks

It looks like you're getting a bit confused about context, and this is leading to faulty XPath selectors.

First problem

You start here:

<xsl:template match="/">
    <bdo_fosfec:RegistrosPagosElement xsi:type="bdo_fosfec:RegistrosPagos" xmlns:bdo_fosfec="http://asocajas.app.com/example" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
        <xsl:apply-templates select="registro54"/>
    </bdo_fosfec:RegistrosPagosElement>
</xsl:template>

So you matched on the logical root element. Within the context of this logical root element, you use xsl:apply-templates -- but with select="registro54". This XPath is looking for any registro54 elements that are immediate children of the context element. However, the immediate child of the logical root is the topmost element in the file, in your case, bdo_fosfec_x003A_RegistrosPagosElement. So this select statement selects nothing.

We can fix this by changing one of two things. Either:

  1. Change your xsl:template match statement to xsl:template match="/bdo_fosfec_x003A_RegistrosPagosElement",
    or
  2. Change your xsl:apply-templates select statement to xsl:apply-templates select="bdo_fosfec_x003A_RegistrosPagosElement/registro54".

Second problem

Even after implementing this first fix, we don't get what we need. Your second template:

<xsl:template match="registro54">
    <registro54 xsi:type="bdo_fosfec:Registro54">
        <registro82 xsi:type="bdo_fosfec:Registro82">
            <C512><xsl:value-of select="C512"/></C512>
            <C614><xsl:value-of select="C614"/></C614>
        </registro82>
    </registro54>
</xsl:template>

So our context is the registro54 element. We try to get values using these two statements:

            <C512><xsl:value-of select="C512"/></C512>
            <C614><xsl:value-of select="C614"/></C614>

These produce nothing, again because the XPaths select nothing. Within the context of registro54, these select statements try to find immediate children of registro54 that are named C512 or C614.

However, if we look at your input XML:

<registro54 xsi:type="bdo_fosfec:Registro54">
    <registro82 xsi:type="bdo_fosfec:Registro82">
        <C512>39756656</C512>
        <C614>YAXMINNI</C614>
    </registro82>
</registro54>

... we see that the C512 and C614 elements are children of registro82 instead. So to actually get these values, change your select statements to:

            <C512><xsl:value-of select="registro82/C512"/></C512>
            <C614><xsl:value-of select="registro82/C614"/></C614>

Conclusion

Remember that select with relative XPaths (any XPath expression that doesn't start with /, the logical root) will only ever select from the starting point of the context element.
