API output not writing to to file using XSLTPROC

[beeboo]

Here is the line to get the data i want

staticGROUPusers=$( curl --user "${apiUSER}:${apiPASS}" --silent --show-error --header "Accept: text/xml" "${url}" )

I then write out a XSLT stylesheet for my needs

cat << EOF > "$folderLOCATION"/stylesheet.xslt
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="text"/>
<xsl:template match="/">
    <xsl:for-each select="computer_group/computers/computer">
        <xsl:value-of select="serial_number"/>
        <xsl:text> </xsl:text>
    </xsl:for-each>
</xsl:template>
</xsl:stylesheet>
EOF

followed up with writing each serial to the file 

serialNUMBERS=(`echo "$staticGROUPusers" | xsltproc "$folderLOCATION"/stylesheet.xslt -`)

Funny thing is, this has worked up to today, which, when i run it now, gives me no entries in the XSLT file (see below)

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="text"/>
<xsl:template match="/">
    <xsl:for-each select="computer_group/computers/computer">
        <xsl:value-of select="serial_number"/>
        <xsl:text> </xsl:text>
    </xsl:for-each>
</xsl:template>
</xsl:stylesheet>

When i run the full script, I immediately get an error

-:10: parser error : Opening and ending tag mismatch: br line 8 and p
</p>
    ^
-:11: parser error : Opening and ending tag mismatch: p line 8 and body
</body>
       ^
-:12: parser error : Opening and ending tag mismatch: body line 5 and html
</html>
       ^
-:12: parser error : Premature end of data in tag html line 1
</html>
       ^
-:1: parser error : Document is empty

^

if i run the command

`echo "$staticGROUPusers" | xsltproc "$folderLOCATION"/stylesheet.xslt -`

i get this error

C02DR8CLMD6R:~ jche$ `echo "$staticGROUPusers" | xsltproc "$folderLOCATION"/stylesheet.xslt -`
-sh: C02VM05YHTD6: command not found

if i try without single quotes

echo "$staticGROUPusers" | xsltproc "$folderLOCATION"/stylesheet.xslt -

it gives me the output in term but no data is written to the file itself

C02DR8CLMD6R:~ jche$ echo "$staticGROUPusers" | xsltproc "$folderLOCATION"/stylesheet.xslt -
C02VM05YHTD6 C02YN39BJG5H C02CG0PDMD6V C02YN3G8JG5H C02ZJ88ZLVDL C02W42CWHTD6 C02DD6PBMD6R C02ZH03ZLVCF C02DR8CLMD6R

My account has r/w to the file also esp since im running locally.

Any ideas as to why or what the alternative could be?

EDIT: nvm, it wasnt that issue, i forgot to pass off env vars to script, apologies!
