dotnet xml: (Type your message here)

--------------------------------
From: Aravind G

Hello all,

I have a peculiar situation.

Following is a small xml snippet in use

<ROOTNODE>
<SPSNODE>
<EXTERNALMESSAGE xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<PHILIPSRIS>
<PERSON xmlns:dt="urn:schemas-microsoft-com:datatypes">
<PATIENT>
<SERVICEEPISODE>
<ORDERENTRY>
<ORDER_STATUS dt:dt="string">SC</ORDER_STATUS>
:
:
:

Through some mapping information I am able to get the element name (viz. ORDER_STATUS) in a variable say RISName.
The need is to get the Value of the element ORDER_STATUS. Since the element name is obtained dynamically, the exact path is not known during the program. Hence I am using the "//" expression suppported to reach the element of interst.

Below is the XSLT snippet used.

<xsl:variable name="RISValue">
<xsl:value-of select="//$RISName"/>
</xsl:variable>

XSLT processor is throwing "Not a valid XPath expression".

1. Can any one kindly clarify if // and $ can be used in conjunction?
2. If there is any way the needed solution can be arrived.

Thanks in advance

Regards
Aravind

You seems to be coding with macros too much :) No macros in XSLT. Use

<xsl:value-of select="//*[name() = $RISName]"/>
