XSLT String Wrap:How do I wrap words in a String at New line character(\n)

问题

We want to write XSLT transformation for given XML. We are trying to text wrap for comment element at newline character on pressing of ENTER KEY. In that, <Comment> elements Splits across 6 different line items after applying XSLT Transformation.

Note: Here "\n" is the linefeed character. It means end the present line and go to a new line.

We tried following :

Pattern observed in it:
<StockCode> element is blank for all having comment substring at each line items. while StockCode element is having value for all those <comment> element is blank
<OrderDetail> is repeating node here.

Input XML :

<?xml version="1.0" encoding="WINDOWS-1252"?>

To minimize the problem to the main question here, consider the following stylesheet:

XSLT 2.0

<xsl:stylesheet version="2.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:strip-space elements="*"/>

<!-- identity transform -->
<xsl:template match="@*|node()">
    <xsl:copy>
        <xsl:apply-templates select="@*|node()"/>
    </xsl:copy>
</xsl:template>

<xsl:template match="OrderDetails">
    <xsl:copy>
        <xsl:variable name="stockcode" select="StockLine/StockCode" />
        <xsl:for-each select="tokenize(StockLine/Comment, '\\n')">
            <StockLine>
                <xsl:copy-of select="$stockcode"/>
                <Comment>
                    <xsl:value-of select="normalize-space(.)"/>
                </Comment>
                <OrderLineID>???</OrderLineID>
            </StockLine>
        </xsl:for-each>
    </xsl:copy>
</xsl:template>

</xsl:stylesheet>

Applied to the following input:

XML

<SalesOrders xmlns:xsd="http://www.w3.org/2001/XMLSchema-instance" xsd:noNamespaceSchemaLocation="SORTOIDOC.XSD">
  <Orders>
    <OrderHeader>

      <SalesForceOrderNumber>ORD-411324</SalesForceOrderNumber>
    </OrderHeader>
    <OrderDetails>
      <StockLine>
        <StockCode>NIL</StockCode>
        <Comment>EDIORDER-SAVE COMMENTS\n C3 Generic\n LOC 0833\n Expected arrival 01/07/2016\n  OTYPE NE\n TRKPC 01 GM/00007643020008361321</Comment>
      </StockLine>
    </OrderDetails>

the result will be:

I have no idea where the contents of OrderLineID are supposed to come from.

Important:

If the input Comment contains actual linefeed characters - IOW, if your actual input is:

XML

<SalesOrders xmlns:xsd="http://www.w3.org/2001/XMLSchema-instance" xsd:noNamespaceSchemaLocation="SORTOIDOC.XSD">
  <Orders>
    <OrderHeader>
      <Customer>000016</Customer>
      <OrderDate>2016-04-19</OrderDate>
      <SalesForceOrderNumber>ORD-411324</SalesForceOrderNumber>
    </OrderHeader>
    <OrderDetails>
      <StockLine>
        <StockCode>NIL</StockCode>
        <Comment>EDIORDER-SAVE COMMENTS
C3 Generic

TRKPC 01 GM/00007643020008361321</Comment>
      </StockLine>
    </OrderDetails>
  </Orders>
</SalesOrders>

then use:

<xsl:for-each select="tokenize(StockLine/Comment, '\n')">

Added:

Given the following input:

the following stylesheet:
