Calling another element by attribute value in same context?

[MaKSiNG]

I have the following XML which define the options available to a radio button and which option is checked as default:

<item name="options">
   <value>
      <item name="description">
         <value>Yes</value>
      </item>
      <item name="default"/>
   </value>
   <value>
      <item name="description">
         <value>No</value>
      </item>
      <item name="default">
         <value>yes</value>
      </item>
   </value>
</item>

I am using the following piece of XSL to transform this into HTML:

<xsl:for-each select="value/item/value/item[@name='description']">
<xsl:variable name="pos2" select="position () - 1"/>
<tr valign="top">
<td class="cn-cont-nopad" height="10" width="10">
   <xsl:element name="input">
   <xsl:attribute name="type">radio
   </xsl:attribute>
   <xsl:attribute name="name">
      <xsl:value-of select="$rdBtnName" />
   </xsl:attribute>
   <xsl:attribute name="id">radiobutton0_
      <xsl:value-of select="$pos"/>
   </xsl:attribute>
[COLOR=blue]   <xsl:attribute name="value">radiobutton0_
      <xsl:value-of select="$pos"/>_
      <xsl:value-of select="$pos2"/>
   </xsl:attribute>[/color]
   <xsl:attribute name="class">cn-form-field
   </xsl:attribute>
[COLOR=red]   <xsl:if test="item[@name='default']/value='yes'">
   <xsl:attribute name="checked">checked</xsl:attribute>
   </xsl:if>[/color]
   </xsl:element>
</td>
<td class="cn-form-radio-text" height="10" width="190">
<xsl:value-of select="value" />
</td>
</tr>
</xsl:for-each>

My problem is two-fold:

1. I am building the <input> tag bit by bit using <xsl:element> and <xsl:attribute> and populating the attributes with variables, text and content from the XML. If you look at the value attribute in blue, I am building it using 2 variables and text. When I look at the rendered HTML I get lots of spaces between the various components I am trying to put together in a single string. This stops the HTML being read as a single line and I am not getting a radio button displayed. I have taken the resulting HTML and deleted all the space from these attributes and it works fine. How do I stop all these extra spaces being added?

2. I am having difficulty locating the node I need in the highlighted red <xsl:if> statement. My <xsl:for-each> statement puts me on a certain level of nodes; the item node with attribute description, but how do I now specify the item node with attribute default, which is also on the same level?


Thx,

First of all, I think you might consider simplifying your xml. For example:

<options>
  <item default="False">Yes</item>
  <item default="True">No</item>
</options>

Then for your questions:
1: use the concat()-function:
<xsl:attribute name="value">
<xsl:value-of select="concat(radiobutton0_,$pos,'_',$pos2)" />
</xsl:attribute>

2: there is an x-path-expression for parent-node (../), so you can ask if the parent-node has a childnode...etc:
<xsl:if test="../item[@name='default']/value='yes'">
In the xml I suggested above, you don't have to stunt like that...

Enjoy,
