Xsl Preserving output text order

I’m using XSLT to convert xml documents that contains complex structure of data, free text etc. into a HTML document.
Documents that I process can be with or without structural items, and if present structural tags can be nested arbitrarily. Data tags can refers to
any type of goods, so I don’t know in advance the content of the XML doc.

Documents looks like

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<?xml-stylesheet type="text/xsl" href="my.xsl"?>
<doc>
  <elementStructure type="tag">
     The following items are cars: 
    <Car id="12" type="data" value="Ferrari"> this is a sport car.
     <structureLev2 type="tag">
       <Model id="432" value="458" />
      <Rim id="55" value="wheels of car" type="data"> 
      <Tire id="234" value="front" type="data">
       <Note id="33" value="special tire" type="data"/> size of front is less that rear.
       <TypeTire id="44" value="radial tire" type="data"/>
      </Tire>
    </Rim>
     </structureLev2>
   </Car>
  </elementStructure>
  <elementStructure type="tag">
    Other text
    <Car id="22" type="data" value="Ford">
      this is a family car.
      <structureLev2 type="tag">
        <Model id="872" value="Mondeo" />
        <Rim id="45" value="wheels of car" type="data">
          <Tire id="734" value="front" type="data">
            <Note id="63" value="normal tire" type="data"/> spare tire could be replaced by run-flat.
            <TypeTire id="84" value="tubeless tire" type="data"/>
          </Tire>
      </Rim>
    </structureLev2>
    </Car>
  </elementStructure>
</doc>

The desiderata HTML document should looks something like:

<section>
 Some text....
 <ul>     
  <li>Car - Ferrari (this is a sport car.)</li>
  <li>Rim - wheels of the car:</li>
   <ul>
    <li>Tire - front Note: special tire (size of front is less than rear).</li>
    <li>TypeTire - radial tire
   </ul>
 </ul>
</section>

Actually I don’t know if it is a good solution but since I don’t know if my xml contains or not structural tags, I used a “switch” to choose between two main templates.

<?xml version="1.0"?>
 <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
 <xsl:output method="html"/>
 <xsl:strip-space elements="*"/>
 <xsl:template match="doc">
 <html>
   <body>
    <xsl:choose>
     <xsl:when test="//*[@type='tag']">
       <xsl:call-template name="stuct" />
     </xsl:when>
     <xsl:otherwise>
       <xsl:call-template name="plain" />
     </xsl:otherwise>
    </xsl:choose>
   </body>
 </html>
 </xsl:template>
 <xsl:template match="doc/*[@type='tag']" name="stuct">
  <h3>
   <xsl:value-of select="text()"/>
  </h3>
    <xsl:apply-templates mode="str"/>
 </xsl:template>
 <xsl:template match="doc/*[@type='tag']" mode="str">
  <ul>
   <li>
    <xsl:call-template name="dataElem"/>
    <xsl:apply-templates mode="str"/>
   </li>
  </ul>
 </xsl:template>
 <xsl:template match="doc/*[@type='data']" name="dataElem">
  <xsl:for-each select="descendant::node()[not(@type='tag')]">
   <xsl:value-of select="name(.)"/>: <xsl:value-of select="@value" /> (<xsl:value-of select="text()"/>)<br/>
  </xsl:for-each>
 </xsl:template>
 <xsl:template match="doc/*[@type='data']" name="plain">
    <xsl:call-template name="dataElem" />
  </xsl:template>
 </xsl:stylesheet>

Among all the problems that I got, starting from the code itself 🙂 one problem that arises is about the text. I want that the text beetween tags possibly appears one time only, and after the “parsed” element. Is it possible?

    It is difficult to discern the logic of the required transformation from a single, incomplete example. Moreover, I suspect that the provided output is actually incorrect – as there is no apparent reason for promoting “Rim” to be a sibling of “Car’ when in the original document it is a child thereof.

    Perhaps something like this could work for you:

    XSLT 1.0

    When applied to your example input, the result will be:

    The following items are cars:

    Car - Ferrari (this is a sport car.)

    Rim - wheels of car

    Tire - front (size of front is less that rear.)

    Note - special tire
    TypeTire - radial tire

    Other text

    Car - Ford (this is a family car.)

    Rim - wheels of car

    Tire - front (spare tire could be replaced by run-flat.)

    Note - normal tire
    TypeTire - tubeless tire
