RE: Detecting character combination in XML

<xsl:template match="book[contains(description, ' q')]">
   <xsl:value-of select="title"/>
</xsl:template>

<bookshelf>
  <book>
    <title>A</book>
    <desc>This qis an interesting qbook about...</desc>
  </book>
  <book>
    <title>B</book>
    <desc>This is another good book</desc>
  </book>
</bookshelf>

When you look at the description (desc) you can see that the first text
contains sometimes a "q" (non capital letters) before a word. I would like a
script that detects all books and return their titles, when the description
contrains a space and a q next to each other somewhere in the text. This
should be only if the q is a non-capital letter. I am using Xalan and don't
really want to change the parser for this task...

This text output here would look that:

A

I am aware that this might be sometimes incorrect but I just want to use
this output to crosscheck and support my manual work.

Also, I have some variations for this:

variation a) I would like to detect the following ". q".
variation b) I would like to detect teh following "? q".
