XSLT- Get substring and pass it as parameters to java function

Question

In the below code snippet, I am trying to get the substring of my @imageMeta node, append some more path location and pass it as a parameter to my java method through XSLT.

<xsl:variable name="imagePathFrom" select="/config/assets/images/{substring-after(@imageMeta,'/')}" />
<xsl:variable name="imagePathTo" select="'/dev/svn_root/platform/system'" />
<xsl:value-of select="filecopy:copyFile($imagePathFrom, $imagePathTo)"/>

My @imageMeta node data looks like Images/common/dialog/dialogue_black.png. I have to convert the above path to images/common/dialog/dialogue_black.png (note the change of capital 'I' to small 'i') and append some more path data.

So my final path entry should look like "/config/assets/images/common/dialog/dialogue_black.png". When i run my code snippet i get an error stating:

line 51: Error parsing XPath expression '/config/assets/images/{substring-after(@imageMeta,'/')}'.'

Please help.

<xsl:variable name="imagePathFrom" select="/config/assets/images/{substring-after(@imageMeta,'/')}" />

There are two problems here:

A syntax error -- a select is probably the only attribute attribute in XSLT that cannot contain an AVT.
Even without the AVT, this would attempt to select all /config/assets/images nodes, but the intent is that the variable must contain the string "/config/assets/images"

Solution to both problems:

<xsl:variable name="imagePathFrom" select=
 "concat('/config/assets/images/', substring-after(@imageMeta,'/')" />

Alternative solution:

<xsl:variable name="imagePathFrom" select=
 "concat('/config/assets/',
         translate(substring(@imageMeta, 1, 1),
                   $vUpper,
                   $vLower
                   ),
         substring(@imageMeta, 2)
         )" />

where $vLower and $vUpper are defined, respectively, as:

'abcdefghijklmnopqrstuvwxyz'

and

'ABCDEFGHIJKLMNOPQRSTUVWXYZ'

There is one problem in your code: <xsl:variable name="imagePathFrom" select="/config/assets/images/{substring-after(@imageMeta,'/')}" />

It suppose to be .. <xsl:variable name="imagePathFrom" select="substring-after(/config/assets/images/@imageMeta,'/')" />

This suggestion fixes the syntax, but it is not the correct one: /config/assets/images is the disk path, not a path in the source XML, Dimitre solution is the right one

infant programmer 'Aravind' suggestion will solve your parse error.

You also mentioned you wanted to lower-case the capital i. Two options here:

Using XSLT 1.0, this StackOverflow answer explains how to lower-case the first character of a string. It won't work for Unicode characters such as 'Í' but you probably don't need it.
XSLT 2.0 has a lower-case function, which will lower-case your entire string, and may not be what you're looking for.
