to save session:getxml result in a variable

[Elvira Nieto Carretero <en...@sadiel.es>]

Hello again all!!

I create a session with

<session:setxml context="lastSearch" path="/search">

  <session:getxml context="request" path="/querystring" /> 

</session:setxml>

Once i created it i want to save in a param or variable so i can use anywhere.

If i put in my code directly 

<session:getxml context="lastSearch" path="/search" />

, the value of my session print in my page but if i do  

<xsl:variable name="mySearch">

  <session:getxml context="lastSearch" path="/search" />

</xsl:variable>

...

<xsl:value-of select="$mySearch"/>

It isn't print nothing, it's blank my variable $mySearch.



Why?

thank you very much

In which way exactly? A string or elements or ...?

You create a result tree fragment here: 
http://www.w3.org/TR/xslt#section-Result-Tree-Fragments. It is a mixture 
of an XML structure and a string: though the xml nodes are in it, only 
string functions can be executed on it.

> <xsl:value-of select="$mySearch"/>

Here you retrieve the string value of this result tree fragment which is 
the concatenation of all text nodes in it. If the above session:getxml 
results in a element-only XML structure you will see no output, you have 
to use copy-of instead then.
