Rather than using grep, sed or awk to transform the XML into the required output, it is better to use an XSLT processor.

If you have (Gnome) libxsl/libxslt installed, it comes with xsltproc a command line interface to a XSLT v1.0 compliant processor.

Here is a stylesheet which performs the required transformation using xsltproc:
Code:
$ cat file.xsl
<?xml version="1.0"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

<xsl:output method="text" omit-xml-declaration="yes" />

<xsl:template match="id">
    <xsl:value-of select="@v"/><xsl:text>&#xa;</xsl:text>
</xsl:template>

<xsl:template match="/">
  <xsl:apply-templates select="/wfregistry/completedworkflows/id" />
</xsl:template>

</xsl:stylesheet>

$ xsltproc file.xsl file.xml

xml2-config

GNOME-XML(1)							       1.1.0							      GNOME-XML(1)

NAME

       xml-config - script to get information about the installed version of GNOME-XML

SYNOPSIS

       xml-config [--prefix[=DIR]] [--libs] [--cflags] [--version] [--help]

DESCRIPTION

       xml-config  is  a  tool	that  is  used to determine the compile and linker flags that should be used to compile and link programs that use
       GNOME-XML.

OPTIONS

       xml-config accepts the following options:

       --version
	       Print the currently installed version of GNOME-XML on the standard output.  Add the --static option to print the linker flags  that
	       are necessary to statically link a GNOME-XML program.

       --libs  Print the linker flags that are necessary to link a GNOME-XML program.

       --cflags
	       Print the compiler flags that are necessary to compile a GNOME-XML program.

       --prefix=PREFIX
	       If  specified,  use  PREFIX  instead  of  the  installation  prefix that GNOME-XML was built with when computing the output for the
	       --cflags and --libs options. This option must be specified before any --libs or --cflags options.
