I have come up with a way that is handling this circumstance, by testing for
child nodes rather than just child elements of para element. It is working
with what I see so far.
Added below in para template.
<xsl:for-each select="node()"> <!—before the select was “child::*” à
<!—various other xsl:if’s for possible elements à
<xsl:if test="self::processing-instruction()">
<xsl:if test="following-sibling::node()[1][self::text()]">
<xsl:value-of
select="following-sibling::node()[1][self::text()]"/>
</xsl:if>
</xsl:if>
</xsl:for-each>

As far as an XML parser is concerned you have 3 nodes within the “para”
element; two separate text nodes with the PI in between them.
Your XSL would need to string both text nodes together instead of just showing
the first one.
I’m a bit rusty on this sorry, but there should be a couple of ways to do it.
Cheers,

Sorry, meant to add. I think the expected behavior in textual content would be
to be able to ignore the processing instruction. It seems to be ignored if it
occurs in places other than textual content..
<?xml version="1.0" encoding="UTF-8"?>
<example>
<para> text con<?Pub Caret?>tent here </para><?Pub Caret?>
<para>more text content here </para>
</example>
The second instance of <?Pub Caret?> above is ignored.

OK, I understand what you mean now. Your editor/authoring tool adds those <?Pub
Caret?> and you don't want that to break your PDF generation.
I don't know what the expected behavior should be. I will have to investigate.

Xml simple example:

<para> text con<?Pub Caret?>tent here </para>

Xsl from parent template:
<fo:block font-size="10pt" text-align="left" padding-before="1mm"
margin-left="1mm" margin-right="1mm" padding-after="1mm" font-weight="bold"

Simple xsl para template(para template I do a lot of testing for child elements
of para and do formatting accordingly for each different element that can
appear in the para besides text)
But simply if just text in para element as below :
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl= <http://www.w3.org/1999/XSL/Transform>

<xsl:value-of select="text()"/>

Subject: Re: xml processing instructions in textual content
So, are you generating PDF from XML and XSL, or from FO?
For instance, as an example, if I want PDF to show XML content, and I start
from XML and XSL then I put this in the XML file:
<example>
<![CDATA[
<?xml version="1.0" encoding="UTF-8"?>
<fo:root xmlns:fo= <http://www.w3.org/1999/XSL/Format>
"http://www.w3.org/1999/XSL/Format";>
<fo:layout-master-set>
<fo:simple-page-master margin="2cm"
page-width="21.0cm" page-height="29.7cm" master-name="A4-portrait">
<fo:region-body />
</fo:simple-page-master>
</fo:layout-master-set>
<fo:page-sequence master-reference="A4-portrait">
<fo:flow flow-name="xsl-region-body">
<fo:block>Hello World!</fo:block>
</fo:flow>
</fo:page-sequence>
</fo:root>
]]>
</example>
and something like this in the XSL file:
<fo:block>
<xsl:apply-templates select="example" />
</fo:block>
<xsl:template match="example">
<fo:block font-size="12pt" linefeed-treatment="preserve"
white-space-treatment="preserve" white-space-collapse="false"
font-family="monospace">
<xsl:value-of select="." />
</fo:block>
</xsl:template>
Then fop -xml example.xml -xsl example.xsl -pdf example.pdf generates a PDF
with the example you see above inside the <![CDATA[]]>.
If you are working with FO, then you can use the above example and fop -xml
example.xml -xsl example.xsl -foout example.fo to see how it should look like:
<fo:block font-family="monospace" white-space-collapse="false"
white-space-treatment="preserve" linefeed-treatment="preserve" font-size="12pt">
<?xml version="1.0" encoding="UTF-8"?>
<fo:root xmlns:fo= <http://www.w3.org/1999/XSL/Format>
"http://www.w3.org/1999/XSL/Format">
<fo:layout-master-set>
<fo:simple-page-master margin="2cm"
page-width="21.0cm" page-height="29.7cm" master-name="A4-portrait">
<fo:region-body />
</fo:simple-page-master>
</fo:layout-master-set>
<fo:page-sequence master-reference="A4-portrait">
<fo:flow flow-name="xsl-region-body">
<fo:block>Hello World!</fo:block>
</fo:flow>
</fo:page-sequence>
</fo:root>
</fo:block>

I am encountering xml processing instructions in textual content. Example: “

The resulting pdf from using FOP is “ text con” followed by content from the
next element. The remainder of the text content following the processing
instruction “tent here” is left out.
Is this a bug? Is there something I can configure in FOP config.xml to handle
this? Processing instructions are allowed in textual content of xml elements.
Using FOP 1.0, Windows 7, JDK 1.6.0_26
