RE: [xsl] How can I test the last preceding text character?

[Sascha Mantscheff <922492@xxxxxx>]

Thank you. Additional question:

-- Example --------------------------
<text xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; version="2.0">
x
<a>
    This is parent text a not ending with an x.
    <d>This ends with an x</d>
        <e>This should issue a message.</e>
    This is parent text ending with an x
</a>
</text>
-- /Example --------------------------

What irritates me is that in Oxygen the XPath 
  //e/preceding::node()[1]
highlights the blank space before <e>, while
  //e/preceding::node()[2]
highlights the d element. But when I run Saxon on the example with the
the test 
	<xsl:if test="ends-with(preceding::node()[1],'x')"> 
it fires a the e element and refers to the d element, not to the blank
space.

Obviously, this is due to the 
    <xsl:strip-space elements="*"/>
directive in the XSL sheet. Can the XPath query control in the Oxygen
IDE be configured to behave likewise?

Thanks again for your fast response.
s.m.
