XSLT : How do i assign Constant value using XML element

Question

We have input XML. In that,We tried to put constant value using <LineActionType> element.

We basically want to add <LineActionType >A<LineActionType /> this element constant value on each Comment Line Tag. that is

 <CommentLine>
                    <Comment>Comment#1</Comment>
                    <OrderLineID>OR-1810143</OrderLineID>
                    <UserDefined>3</UserDefined>
                    <LineActionType >A<LineActionType />
                 </CommentLine>

Input XML

<?xml version="1.0" encoding="UTF-8"?>
<SalesOrders xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:xsd="http://www.w3.org/2001/XMLSchema-instance" xsd:noNamespaceSchemaLocation="SORTOIDOC.XSD">
   <Orders>
      <OrderHeader>
         <CustomerPoNumber>Manual Order 1</CustomerPoNumber>
         <OrderActionType>A</OrderActionType>
      </OrderHeader>
      <OrderDetails>
         <StockLine>
            <CustomerPoLine>9999</CustomerPoLine>
            <StockCode>abc-1</StockCode>
            <StockDescription>ASSEMBLED</StockDescription>
            <OrderQty>2.0</OrderQty>
            <OrderUom>EA</OrderUom>
            <PriceUom>EA</PriceUom>
            <AlwaysUsePriceEntered>Y</AlwaysUsePriceEntered>
            <UserDefined>1</UserDefined>
            <OrderLineID>OR-1810141</OrderLineID>
         </StockLine>

            <StockDescription>TARGET SOAP PDQ 2014 ASSEMBLED</StockDescription>
            <OrderQty>3.0</OrderQty>
            <OrderUom>EA</OrderUom>
            <PriceUom>EA</PriceUom>
            <AlwaysUsePriceEntered>Y</AlwaysUsePriceEntered>
            <UserDefined>2</UserDefined>
            <OrderLineID>OR-1810142</OrderLineID>
         </StockLine>
         <CommentLine>
            <Comment>Comment#1</Comment>
            <OrderLineID>OR-1810143</OrderLineID>
            <UserDefined>3</UserDefined>
            <LineActionType />
         </CommentLine>
         <CommentLine>
            <Comment>Comment#2</Comment>
            <OrderLineID>OR-1810144</OrderLineID>
            <UserDefined>4</UserDefined>
            <LineActionType />
         </CommentLine>
      </OrderDetails>
   </Orders>
</SalesOrders>

We tried following XSLT 2.0:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xs="http://www.w3.org/2001/XMLSchema" version="2.0">
   <xsl:output method="xml" encoding="Windows-1252" indent="yes" />
   <xsl:template match="@*|node()">
      <xsl:copy>
         <xsl:apply-templates select="@*|node()" />
      </xsl:copy>
   </xsl:template>
   <xsl:template match="OrderDetails">
      <xsl:copy>
         <xsl:apply-templates select="*">
            <xsl:sort select="xs:integer(UserDefined)" />
         </xsl:apply-templates>
      </xsl:copy>
   </xsl:template>
   <xsl:template match="StockLine[not(StockCodeDescription) and not (OrderQty) and not(Price)]">
      <CommentLine>
         <Comment>
            <xsl:value-of select="StockCode" />
         </Comment>
         <xsl:copy-of select="OrderLineID" />
         <xsl:copy-of select="UserDefined" />
        </CommentLine>
   </xsl:template>
   <xsl:template match="CommentLine[OrderLineID = preceding-sibling::StockLine/OrderLineID and not(Comment)]" />
   <xsl:template match="CommentLine[some $sib in preceding-sibling::CommentLine satisfies deep-equal(., $sib)]" />
</xsl:stylesheet>

EXPECTED OUTPUT :

<?xml version="1.0" encoding="UTF-8"?>

   </Orders>
</SalesOrders>

ANY help on it would be much appreciated ?

Answer 1

Firstly note that <LineActionType >A<LineActionType /> is not valid XML, so I am assuming you mean <LineActionType>A</LineActionType> .

Anyway, if all CommentLine elements had a LineActionType and you just wanted to set them all to A , you could just add this template along with the identity template

<xsl:template match="CommentLine/LineActionType">
   <xsl:copy>A</xsl:copy>
</xsl:template>

Alternatively, if LineActionType is not always present under a CommentLine , you could try adding these two templates instead. One to add it under any CommentLine , and another to prevent any existing one being output (so that it doesn't get output twice)

<xsl:template match="CommentLine">
   <xsl:copy>
      <xsl:apply-templates select="@*|node()" />
      <LineActionType>A</LineActionType>
   </xsl:copy>
</xsl:template>

<xsl:template match="CommentLine/LineActionType" />
