Is this within an XSLT stylesheet? 1.0 or 2.0?

When in XSLT, an XML character reference like ' is expanded before
XPath gets to see it. So the expression XPath sees is

concat('$content-file/Doc/Field[@FieldName='',{$data},'']/table/row')

In 2.0 (like in SQL), a double apos within an apos-delimited string
represents a single apos, which would account for the output you are seeing.

In 2.0 you can therefore do

concat('$content-file/Doc/Field[@FieldName=''',$data,''']/table/row')

In 1.0 it's simplest to declare a variable:

<xsl:variable name="apos">'</xsl:variable>

then

concat('$content-file/Doc/Field[@FieldName=',$apos, $data, $apos,
']/table/row')

Either way, your curly braces are very wrong. Curlies never appear inside an
XPath expression, they are only used to delimit an XPath expression embedded
in enclosing literal text.
