xpath syntax?

[inetquestion]

<xml>
<key name="Tokens\Encotone=4086" friendlyName="Encotone">
<param name="A_1" />
<param name="B_2" />
<param name="C_3" />
</key>

<key name="Tokens\Encotone=4087" friendlyName="Encotone">
<param name="A_4" />
<param name="B_5" />
<param name="C_6" />
</key>
</xml>

I'm trying to find the xpath syntax for the "param" with a name of
"B_5".
Can someone tell me if the entry below is correct?

"xml/key/@friendlyName=Econotone/attribute/@name=B_5"

Also I'm looking for a way to replace that entire element once i'm able
to select it with xpath, but haven't found a good way to do that yet.
Any suggestions woudl be appreciated.

"/xml/key[@friendlyName="Econotone"]/param[@name=B_5]"

If you don't understand why, start by reading a good xpath tutorial.

XPath per se has no replacement mechanism. If you're using the DOM Level
3 XPath API to evaluate this path, you can alter the returned node using
DOM methods on that node. If you're using XSLT, you'd output the
replacement rather than outputting the node itself. Again, see tutorials
on those tools for more info.

Whups. Typos in the quoting of values; sloppy of me.
"/xml/key[@friendlyName='Econotone']/param[@name='B_5']"

There's also a typo by the OP for "Econotone" vs. "Encotone"
Sometimes the simple stuff like this can confuse the hell out of you -
you think it's some subtle XPath problem when really it's just a
trivial string typo.

Good catch. Don't assume posted code has been tested... <smile/>
