    <p>In Orbeon Forms I need to create a component (using XBL) that when bound to an instance like</p> <pre><code>&lt;OCinstructionitem&gt; &lt;OCp&gt;paragraph 1&lt;/OCp&gt; &lt;OCp&gt;paragraph 2 &lt;OCem&gt;with italics part&lt;/OCem&gt; rest of paragraph 2 &lt;/OCp&gt; &lt;/OCinstructionitem&gt; </code></pre> <p>creates an editable div like this:</p> <pre><code>&lt;div contentEditable="true"&gt; &lt;p&gt;paragraph 1&lt;/p&gt; &lt;p&gt;paragraph 2 &lt;i&gt;with italics part&lt;/i&gt; rest of paragraph 2 &lt;/p&gt; &lt;/div&gt; </code></pre> <p>My thought was that I need to do this using XSLT. I get this working when the to-be-transformed XML is inside the xforms document:</p> <pre><code>&lt;oc:instructionitem&gt; &lt;OCinstructionitem&gt; &lt;!-- here the xml of above --&gt; ... &lt;/OCinstructionitem&gt; &lt;/oc:instructionitem&gt; </code></pre> <p>but I want to let the XSLT operate on the bound node as in:</p> <pre><code>&lt;oc:instructionitem ref="OCinstructionitem"/&gt; </code></pre> <p>However, I canot access the bound node from the XSLT.</p> <p>My question: is that just not possible? Or do I have to modify my XBL? </p> <p>My XBL code: </p> <pre><code>&lt;xbl:binding id="oc-instructionitem" element="oc|instructionitem"&gt; &lt;xbl:template xxbl:transform="oxf:xslt"&gt; &lt;xsl:transform version="2.0"&gt; &lt;xsl:template match="@*|node()" priority="-100"&gt; &lt;xsl:apply-templates select="@*|node()"/&gt; &lt;/xsl:template&gt; &lt;xsl:template match="text()" priority="-100" mode="in-paragraph"&gt; &lt;xsl:copy&gt; &lt;xsl:value-of select="."/&gt; &lt;/xsl:copy&gt; &lt;/xsl:template&gt; &lt;xsl:template match="OCem" mode="in-paragraph"&gt; &lt;x:i&gt;&lt;xsl:value-of select="."/&gt;&lt;/x:i&gt; &lt;/xsl:template&gt; &lt;xsl:template match="OCp"&gt; &lt;x:div&gt; &lt;xsl:apply-templates mode="in-paragraph"/&gt; &lt;/x:div&gt; &lt;/xsl:template&gt; &lt;xsl:template match="/*"&gt; &lt;x:div contentEditable="true"&gt; &lt;xsl:apply-templates/&gt; &lt;/x:div&gt; &lt;/xsl:template&gt; &lt;/xsl:transform&gt; &lt;/xbl:template&gt; &lt;/xbl:binding&gt; &lt;/xbl:xbl&gt; </code></pre> <p>Any help would be greatly appreciated,</p> <p>edit: after helpfull comment of tohuwawohu (below) It seems that you need to define a variable which is bound to the instance data. Like this:</p> <pre><code>&lt;xsl:template match="oc:instructionitem"&gt; &lt;xforms:group xbl:attr="model context ref bind" xxbl:scope="outer"&gt; &lt;xxforms:variable name="binding" as="node()?" xxbl:scope="inner" &gt; &lt;xxforms:sequence select="." xxbl:scope="outer"/&gt; &lt;/xxforms:variable&gt; &lt;xforms:group xxbl:scope="inner"&gt; &lt;!-- Variable pointing to external single-node binding --&gt; &lt;xforms:group ref="$binding"&gt; &lt;xsl:call-template name="main"/&gt; &lt;/xforms:group&gt; &lt;/xforms:group&gt; &lt;/xforms:group&gt; &lt;/xsl:template&gt; &lt;xsl:template name="main"&gt; &lt;x:div contentEditable="true"&gt; &lt;xforms:repeat nodeset="*"&gt; &lt;xsl:call-template name="paragraph"/&gt; &lt;/xforms:repeat&gt; &lt;/x:div&gt; &lt;/xsl:template&gt; </code></pre> <p>However, the XSLT elements still cannot act on the data. It can only generate XFORMS elements, which can act on the data. This means that something like &lt;xsl:template match="OCp"&gt; will never be selected. This is why the above code uses named templates. So the question still stands: can the bound data be made available to the xslt code?</p> <p>Martijn</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
