You need to use double quotes. By the way, you can also avoid cat command and avoid escaping all slashes, providing a sed "delimiter" other than "/" (in my example I've used "!"):

Code:
NEW_URL="http://abc.def.com/xyz.dtd"

sed "s!http://[^ ]*dtd!${NEW_URL}!" dir/filename1 > dir/newfile.xml

NAME

       trang - convert between different schema languages for XML

SYNOPSIS

       trang [-I rng|rnc|dtd|xml] [-O rng|rnc|dtd|xsd] [-i input-param] [-o output-param] input-file ...  output-file

DESCRIPTION

       trang takes as input a schema written in any of the following formats:

	      RELAX NG (XML syntax)

	      RELAX NG (compact syntax)

	      XML 1.0 DTD

       and produces as output a schema written in any of the following formats:

	      RELAX NG (XML syntax)

	      RELAX NG (compact syntax)

	      XML 1.0 DTD

	      W3C XML Schema

       Trang can also infer a schema from one or more example XML documents.

       Trang  uses an internal representation based on RELAX NG.  For each supported input format, there is an input module that converts a schema
       in that input format into this internal representation.	For each supported output format, there is an  output  module  that  converts  the
       internal  representation  into  a schema in that output format.	Thus, any supported input format can be translated to any supported output
       format.

       Trang requires two command-line arguments: the first is the URI or filename of the schema to be translated; the second is the output  file-
       name.

       Trang infers the input and output modules to be used from the extension of input and output filenames as follows:

       .rng   RELAX NG (XML syntax)

       .rnc   RELAX NG (compact syntax)

       .dtd   XML 1.0 DTD

       .xsd   W3C XML Schema

       .xml   XML documents (used as examples from which to infer a schema)

       This inference can be overridden using the -I and -O options.

       When  the input is XML documents used as examples to infer a schema, more than one input file may be specified as arguments.  All the input
       files are specified before the output file.

OPTIONS

       -I rng|rnc|dtd|xml
	      Specifies which input module to use.

       -O rng|rnc|dtd|xsd
	      Specifies which output module to use.

       -i input-param

       -o output-param
	      Specifies a parameter for an input (-i) or output (-o) module.  The -i and -o options may be used multiple times in order to specify
	      multiple	parameters.  There are two kinds of parameter: boolean parameters and string-valued parameters.  A string-valued parameter
	      is specified using the form name=value.  A boolean parameter is specified using the form name or no-name.  The applicable parameters
	      depend on the particular input and output module.  For details, see the HTML documentation.
