Re: problem with transforming mixed content

Thank you very much, Graydon and Dimitre, for your replies! Your solutions work very well and deepened my understanding of XSLT.

There is just one little problem I encountered: The data of the external source comes in a particular namespace. Since I do not want to have the namespace declaration in the output, I use @exclude-result-prefixes in the <xsl:stylesheet> element, which works as expected for the rest of the output produced by my stylesheet and also for the <title> and <subtitle> elements produced by your solutions. However, on the <i> elements, the namespace declaration suddenly shows up, which baffles me. Do you know why that is? And how do I get rid of it?

Best,
Wolfhart

XSLT 2.0:

B <xsl:template match="title//text()" mode="copy-lowercase"><xsl:value-of select="lower-case(.)"/></xsl:template>
</xsl:stylesheet>

When applied on the provided XML document:

<title>THE TITLE OF THE BOOK WITH SOME
B  B <i>ITALICS</i> AND SOME MORE
WORDS: THE SUBTITLE OF THE BOOK WITH SOME
B  B <i>ITALICS</i>
</title>

the wanted result is produced:

<title>the title of the book with some
<i>italics</i> and some more
words</title>
<subtitle> the subtitle of the book with some
<i>italics</i>
</subtitle>

Dear list,

    I would like to ask for your help with the following mixed-content
    problem. I am receiving, from an external source, data in the
    following
    form:

    <title>THE TITLE OF THE BOOK WITH SOME <i>ITALICS</i> AND SOME MORE
    WORDS: THE SUBTITLE OF THE BOOK WITH SOME <i>ITALICS</i></title>

    What I would like to do is
    1) separate the title from the subtitle (i.e., divide the data at the
    colon) and put each in a separate element node;
    2) all the while maintaining the <i> markup;
    3) and perform certain string manipulations on all of the text nodes;
    for the purposes of this post, I will use the example of converting
    upper-case to lower-case.

So the desired output is the following:

    <title>the title of the book with some <i>italics</i> and some more
    words</title>
    <subtitle>the subtitle of the book with some <i>italics</i></subtitle>

How can this be done?

    I know that I can perform string manipulations while maintaining
    the <i>
    markup with templates, i.e., <xsl:template match="text()"/> and
    <xsl:template match="i"/>. But in this case I do not know how to
    divide
    the data at the colon. And I know that I can divide the data at the
    colon with <xsl:value-of select="substring-before(.,': ')"/>, but
    then I
    loose the <i> markup. So I am at a loss.

    Thanks in advance for your help!
