ArterialTool, you really should consider using an XSL aware tool such as xsltproc for this type of work.

For example here is how you can use xsltproc to solve your original question

Code:

$ var=`xsltproc -param which "'min-pool-size'" file.xsl file.xml`
$ echo $var
2
$

where file.xml is your input file and file.xsl is

Code:

<?xml version="1.0"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">

    <!-- pass in as -param which "'value'"  -->
   <xsl;param name=which" />

    <xsl:output method="text'/>

   <xsl:template match="/">
      <xsl:apply-templates/>
   </xsl:template>

   <!-- output nodes that match -->
   <xsl:template match="*" priority="1">
      <xsl:if test="name(.)=$which">
        <xsl:value-of select="."/>
      </xsl:if>
   </xsl:template>

   <!-- eat all other output -->
   <xsl:template match="*|text()" priority="0"/>

</xsl:stylesheet>

XML-XPARSE(1)							   User Commands						     XML-XPARSE(1)

NAME

       xml-xparse - Parse XML documents with entity and URI resolution

SYNOPSIS

       xml-xparse [options] xmlfile

DESCRIPTION

       xml-xparse  is a simple command line tool for parsing and validating XML documents.  It is not an actual XML parser, it just wraps around a
       JAXP Parser, adding support for catalog-based entity and URI resolution.

OPTIONS

       -c catalogfile
	      Load a particular catalog file.  May be specified multiple times.

       -v     Perform a validating parse.  This is the default.

       -w     Perform a well-formed parse, not a validating parse.

       -N     Perform a namespace-aware parse.	This is the default.

       -n     Perform a namespace-ignorant parse.

       -d debuglevel
	      Set the debug level (an integer).  Warnings are shown if the debug level is set to greater than 2.

       -E maxerrors
	      Set the maximum number of errors to display.  The default is 10.

FILES

       /etc/java/resolver/CatalogManager.properties
	      The central catalog manager configuration file used by xml-xparse.
