If you have Python and you know the language, here's an alternative
Code:
import re,os
s = open("file").read()
stringtofind = "<param-name>Number</param-name>\n<param-value>(.*?)</param-value>"
pat = re.compile("%s" % stringtofind,re.M)
number = int(pat.findall(s)[0]) + 1
stringtosub = "<param-name>Number</param-name>\n<param-value>%d</param-value>" % number
replacement = re.sub(stringtofind,stringtosub,s)
open("temp","w").write(replacement)
os.rename("temp","file")

output:
Code:
<c-param>
<param-name>Number</param-name>
<param-value>23</param-value>
<description>my house number</description>
</c-param>
<c-param>
<param-name>Address</param-name>
<param-value>XYZ</param-value>
<description>my house Address</description>
</c-param>
