XSLT 1.0 - how to check when condition for string - xslt

Question

I am trying to conditional check on the input xml file and place the value.
input xml:
<workorder>
<newwo>1</newwo>
</workorder>
If newwo is 1, then I have to set in my output as "NEW" else "OLD"
Expected output is:
newwo: "NEW"
my xslt is:
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xs="http://www.w3.org/2001/XMLSchema" version="2.0">
<xsl:template match="/">
<xsl:apply-templates select="NEWWO" />
</xsl:template>
<xsl:template match="/NEWWO">
<xsl:text>{
newwo:"
</xsl:text>
<xsl:choose>
<xsl:when test="NEWWO != '0'">NEW</xsl:when>
<xsl:otherwise>OLD</xsl:otherwise>
</xsl:choose>
<xsl:text>"
}</xsl:text>
</xsl:template>
Please help me. Thanks in advance!

Answer 1

I see a number of reasons you aren't getting output.
The xpaths are case sensitive. NEWWO is not going to match newwo.
You match / and then apply-templates to newwo (case fixed), but newwo doesn't exist at that context. You'll either have to add */ or workorder/ to the apply-templates (like select="*/newwo") or change / to /* or /workorder in the match.
You match /newwo (case fixed again), but newwo is not the root element. Remove the /.
You do the following test: test="newwo != '0'", but newwo is already the current context. Use . or normalize-space() instead. (If you use normalize-space(), be sure to test against a string. (Quote the 1.))
Here's an updated example.
XML Input
<workorder>
<newwo>1</newwo>
</workorder>
XSLT 1.0
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:output method="text"/>
<xsl:template match="/*">
<xsl:apply-templates select="newwo" />
</xsl:template>
<xsl:template match="newwo">
<xsl:text>{
newwo: "</xsl:text>
<xsl:choose>
<xsl:when test=".=1">NEW</xsl:when>
<xsl:otherwise>OLD</xsl:otherwise>
</xsl:choose>
<xsl:text>"
}</xsl:text>
</xsl:template>
</xsl:stylesheet>
Output
{
newwo: "NEW"
}

You try it as below
<?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="1.0">
<xsl:template match="/">
<xsl:choose>
<xsl:when test="/workorder/newwo = 1">
<xsl:text disable-output-escaping="no"> newwo:New</xsl:text>
</xsl:when>
<xsl:otherwise>
<xsl:text disable-output-escaping="no"> newwo:Old</xsl:text> </xsl:otherwise>
</xsl:choose>
</xsl:template>
</xsl:stylesheet>
