Extracting Data Using SED

Given the following text in a file named extract.txt:
listenPort:=25
smtpDestination:=2
enableSSL:=

I am trying to extract only the value 2 following smtpDestination:=

Someone had suggested I use:
sed -e "s/^smtpDestination:=\(.*\)$/\1/" extract.txt
but this returns:
listenPort:=25
2

Can someone help me correct the RegEx to correctly return only the data I need?

Thanks for any help.

Alex

NAME
scrollkeeper-devel, scrollkeeper-extract, scrollkeeper-gen-seriesid, scrollkeeper-preinstall - utilities for working with OMF documents and the scrollkeeper database SYNOPSIS
scrollkeeper-extract file stylesheet output [stylesheet output...] scrollkeeper-gen-seriesid scrollkeeper-preinstall docfile omf-file1 omf-file2 DESCRIPTION
scrollkeeper-extract is used internally by scrollkeeper to convert DocBook/SGML files to Docbook/XML files if necessary, and to apply a number of transformations to the XML file to extract information from the XML file. scrollkeeper-gen-seriesid generates a globally unique series ID for an OMF file. scrollkeeper-preinstall reads omf_file1, changes the URL attribute of the identifier tag to doc_file and writes the output to omf_file2. scrollkeeper-preinstall can be used during the document installation process to point OMF files to the correct location on the target machine before registration in the scrollkeeper database. OPTIONS
None. OPERANDS
The following operands are supported: docfile Specifies the file path to the document that omf-file1 describes. file Specifies the XML file that is to be used as input for XSLT transformations. omf-file1 Specifies the OMF file that contains metadata for docfile. omf-file2 Specifies the file created by scrollkeeper-preinstall, which contains the same data as omf-file1 except that the URL attribute of the identifier tag is changed to docfile. output Specifies the file that contains the result when the preceding stylesheet has been applied to file. stylesheet Specifies an XSLT transformation to apply. EXAMPLES
Example 1: Creating a New scrollkeeper Series ID example% scrollkeeper-gen-seriesid Example 2: Extracting a TOC From a Document example% scrollkeeper-extract /path/to/xml/file.xml /usr/share/scrollkeeper/stylesheets/toc.xsl /path/to/toc.xml EXIT STATUS
The following exit values are returned: 0 Application exited successfully >0 Application exited with failure FILES
