Hi Jakub,

Usually, just getting the string value of a node will do that.

>   aaa
>   <b>
>     bbb
>     <c>

>   </b>
>   AAA
> </a>

It's very easy from this example to get the string:

"  aaa

    bbb

      ccc

    BBB

  AAA
"
Just do:

  <xsl:value-of select="/a" />

But to get the string that you want:

> aaabbbcccBBBAAA

you need to get rid of the whitespace that's been added to the tree.
The easiest thing to do here is to have a template in 'string' mode
that matches text nodes and gives the normalized value of the string:

<xsl:template match="text()" mode="string">
  <xsl:value-of select="normalize-space()" />
</xsl:template>

and then apply templates to the a element in 'string' mode; the built
in templates will move through the tree to get to the text nodes, and
their normalized values will be returned, concatenated together:

  <xsl:apply-templates select="/a" mode="string" />

Cheers,
