Question

I use the below xslt to transform xmls, it iterates thru the Receipt/Process
nodes and adds type attributes to the nodes. Based on the node’s value it will be string/int/float.
That part works fine.

I also should rename the “Node” node to “Node” concatenated with its index and
add an attribute which should be the “Name” node’s value.

I may have multiple “Nodes” which I would like to convert to something like this:

first Node to where the “Cuda3DLut” is coming from the <Name>Cuda3DLut</Name>

<Node1 type="Cuda3DLut" >
<Input  type="ToolLink" role="Input" format="red,green,blue">Source</Input>
<Lut type="string">Identity</Lut>
<Output type="ToolLink" role="Output" format="red,green,blue">RESULT1</Output>
<bypass type="int">0</bypass>
<nodeRole type="string">viewing</nodeRole>
<nodeShortName type="string">LUT</nodeShortName>
</Node1>

second Node to

<Node2 type="CudaTool" >
...
</Node2>

I also would like to change the “Input” node’s value if it is “MainMedia” to “Source” but only then.

Thanks a lot.

Source XML:

<Receipt>

  <Process>
    <Node>
      <Name>Cuda3DLut</Name>
      <Input>MainMedia</Input>
      <Lut>Identity</Lut>
      <Output>RESULT1</Output>
      <bypass>0</bypass>
      <nodeRole>viewing</nodeRole>
      <nodeShortName>LUT</nodeShortName>
    </Node>
   <Node>
      <Name>CudaTool</Name>
      <Input>MainMedia</Input>
      <Lut>Identity</Lut>
      <Output>RESULT1</Output>
      <bypass>0</bypass>
      <nodeRole>viewing</nodeRole>
      <nodeShortName>LUT</nodeShortName>
    </Node>
  </Process>

This transformation:

<xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
 <xsl:output omit-xml-declaration="yes" indent="yes"/>
 <xsl:strip-space elements="*"/>

 <xsl:template match="Node">
     <xsl:element name="Node{position()}">
       <xsl:attribute name="type">
         <xsl:value-of select="Name"/>
       </xsl:attribute>
       <xsl:apply-templates select="*[not(self::Name)]"/>
     </xsl:element>
 </xsl:template>

 <xsl:template match="Node/*" priority="-1">
  <xsl:copy>
    <xsl:attribute name="type">string</xsl:attribute>
    <xsl:value-of select="."/>
  </xsl:copy>
 </xsl:template>

 <xsl:template match="Node/Input">
   <Input  type="ToolLink" role="Input" format="red,green,blue">Source</Input>
 </xsl:template>

 <xsl:template match="Output">
   <Output  type="ToolLink" role="Output" format="red,green,blue">
     <xsl:value-of select="."/>
   </Output>
 </xsl:template>

 <xsl:template match="bypass">
  <bypass type="int"><xsl:value-of select="."/></bypass>
 </xsl:template>
</xsl:stylesheet>

when applied on the provided XML document:

<Receipt>
    <Process>
        <Node>
            <Name>Cuda3DLut</Name>
            <Input>MainMedia</Input>
            <Lut>Identity</Lut>
            <Output>RESULT1</Output>
            <bypass>0</bypass>
            <nodeRole>viewing</nodeRole>
            <nodeShortName>LUT</nodeShortName>
        </Node>
        <Node>
            <Name>CudaTool</Name>
            <Input>MainMedia</Input>
            <Lut>Identity</Lut>
            <Output>RESULT1</Output>
            <bypass>0</bypass>
            <nodeRole>viewing</nodeRole>
            <nodeShortName>LUT</nodeShortName>
        </Node>
    </Process>
    <Encode>
        <Job>      ...     </Job>
    </Encode>
</Receipt>

produces the wanted, correct result:

<Node1 type="Cuda3DLut">
   <Input type="ToolLink" role="Input" format="red,green,blue">Source</Input>
   <Lut type="string">Identity</Lut>
   <Output type="ToolLink" role="Output" format="red,green,blue">RESULT1</Output>
   <bypass type="int">0</bypass>
   <nodeRole type="string">viewing</nodeRole>
   <nodeShortName type="string">LUT</nodeShortName>
</Node1>
<Node2 type="CudaTool">
   <Input type="ToolLink" role="Input" format="red,green,blue">Source</Input>
   <Lut type="string">Identity</Lut>
   <Output type="ToolLink" role="Output" format="red,green,blue">RESULT1</Output>
   <bypass type="int">0</bypass>
   <nodeRole type="string">viewing</nodeRole>

</Node2>
