Re: [docbook-apps] How to transform the content of a <para> element?

[Christophe HARO <christophe.haro@free.fr>]

Hi Bob,

Thanks for your response.

Has I want to translate all text's nodes of the document, not only texts of <para> elements, I wrote a stylesheet to preprocess the document :

<xsl:output method="xml" encoding="utf-8" />

<xsl:template match="/">
  <xsl:apply-templates />
</xsl:template>

<xsl:template match="text()">
  <xsl:value-of select="translate(.,'T','Z')" />
</xsl:template>

<xsl:template match="@* | node()">
  <xsl:copy>  
	<xsl:apply-templates select="@* | node()" />
  </xsl:copy>
</xsl:template>

Then, all work fine with :
<para>                                    <para>
    This is a text.                           Zhis is a text.
    <emphasis>                                <emphasis>
        This is another phrase.    ==>            Zhis is another phrase.
    </emphasis>                               </emphasis>
</para>                                   </para>

But a sentence that follows </emphasis> before </para> is not outputed :

<para>                                    <para>
    This is a text.                           Zhis is a text.
    <emphasis>                                <emphasis>
        This is another phrase.    ==>            Zhis is another phrase.
    </emphasis>                               </emphasis>
    This was a Test.                      </para>
</para>

Any suggestion to solve this ?

Thank you.
