[xsl] XSLT Concepts

[chirag matkar <chiragmatkarbioinfo@xxxxxxxxx>]

Hello Friends,
I am an Amateur Developer in Xsl transformations.
I work on Research Article XML conversions.
I just want to be clear on some Concepts of XSLT.

1)When we apply a Template<xsl:apply-templates/> the whole text within
the tags in input file data gets applied and new  element  are
processed as we declare them.

So when we use <xsl:value of select=""/> ,additional data is
processed.This results into extra junk data as i have noticed.How to
avoid such circumstances.?

2)Also Suppose we tag the input data with new elements,the tags appear
in the sequence of initial text in the data.How can we sequentially
keep changing order of the data as we wish and apply templates
accordingly.
Example -  we need to tag article title which appears at end in the
input file but we wish to have it tagged first in the output file.ie
change order of tags according to our requirements.


3)Can we template match a tag more than one time and process nodes
within it sequentially?


Thanking You.
