Re: Testing if first child is text or an element?

I've got some markup that allows mixed content in an element. When I
process this content I need to do something different if the element
starts with text vs an element. My content can be like this:

<?xml version="1.0" encoding="UTF-8"?>
<doc>
B  <step >
B B B  <info>
B B B B B  1 The following collection shows examples of non-checklist
B B B B B  lists with nested checklists.
B B B B B  <ul>
B B B B B B B B  <li>This is an unordered list item with a child
B B B B B B B B B B B  checklist.
B B B B B B B B  </li>
B B B B B  </ul>
B B B  </info>
B  </step>
B  <step >
B B B  <info>
B B B B B B  <p>2 The following collection shows examples of non-checklist
B B B B B B B  lists with nested checklists.</p>
B B B B B B  <ul>
B B B B B B B B B  <li>This is an unordered list item with a child
B B B B B B B B B B  checklist.
B B B B B B B B B  </li>
B B B B B B  </ul>
B B  </info>
B  </step>
</doc>

I want it to produce:

+
1 The following collection shows examples of non-checklist
lists with nested checklists.
* This is an unordered list item with a child
checklist.

2 The following collection shows examples of non-checklist
lists with nested checklists.</p>
* This is an unordered list item with a child

So if the <info> starts with text it should add the '+' and if it
starets with an element, add nothing.

B B B B <xsl:template name="list-block-start">

B B B B B B B  <xsl:if test="
B B B B B B B B B B B  ancestor::step ">

B B B B B B B B B B B  <xsl:choose>
B B B B B B B B B B B B B B B  <!-- collapsed tables in

B B B B B B B B B B B B B B B <xsl:when

'collapse')]"/>
B B B B B B B B B B B B B B B  <xsl:otherwise>
B B B B B B B B B B B B B B B B B B B  <xsl:value-of select="$RETURN"/>
B B B B B B B B B B B B B B B B B B B  <xsl:choose>
B B B B B B B B B B B B B B B B B B B B B B B  <xsl:when

B B B B B B B B B B B B B B B B B B B B B B B B B B B  <xsl:choose>
B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B  <xsl:when

of element()">
B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B  <!--

B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B  </xsl:when>
B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B  <xsl:when

of text()">
<xsl:text>+</xsl:text>
B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B

B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B  </xsl:when>
B B B B B B B B B B B B B B B B B B B B B B B B B B B  </xsl:choose>

But do realize that the second info element also starts with a pure
whitespace text node child.

So, unless you strip-space, both your case have a text node child as the
first child, you might want to check

to match the info element that starts with a text node that has more
than whitespace.
