hi david..
The solution that you gave for using
/a/b/*[name()=$path]
works fine..
Thanks a lot..

[number($Index)]
you would have been better to have kept Index as a
number rather than
forcing it back to a number.
ie don't do this:
<xsl:with-param name="Index"><xsl:value-of
select="$Index+1"/></xsl:with-param>
do this
<xsl:with-param name="Index" select="$Index+1"/>
Never use xsl:variable with content instead of a
select attribute
unless you intend to do that. It is quite expensive.
You are starting with a number then generating a
text node with the
string value of that number, placing that in a root
node, making a result
tree fragment of that, and then converting the whole
thing back to a
number with number().
The purpose is solved but i want to know if it is
the
right thing to do....
Impossible to say given your description, but it
seems unlikely that
you need recursion at all. As I said in my reply
your stated aim of
concatenating the text can be done with a single
line:
<xsl:copy-of select="Type/text()"/>
<xsl:variable name="fullpath"
select="concat('/a/b/',$path)"/>
This is a FAQ Xpaths are not strings, they are part
of the syntax of
the language. In C or Java or most other programming
languages, if you
had a variable x with value 2 and the string "x+2"
it wouldn't be
trivial to get the value 4: you'd have to write a
parser to parse the
string and access the referenced constructs. It is
the same in XPath,
if you have a string that looks like an XPath then
this is no use to you
unless you have an Xpath parser that is callable at
run time. Some
systems do have such an extension, eg saxon:evaluate
but it is not a
standard part of the language.
In simple cases such as your first
<xsl:variable name="path">c</xsl:variable>
(which would be better as
<xsl:variable name="path" select="'c'"/>
)
<!-- Now i am trying to access the dynamic path
a/b/c
you can do
/a/b/*[name()=$path]
This really is a FAQ see the faq that is linked from
the home page of
this list.
