Ho to filter elements from a source node with ION mapper?

Legacy Contributor

Hi,

we want to transform a Sync.ContentDocument BOD into a Process.ContentDocument BOD. The Sync.ContentDocument contains a node "DocumentResource" which contains as elements the original document and also "Preview" and "Thumbnail" resource. In the Process.ContentDocument in Node "DocumentResource" only the original document is allowed. So we have to filter out during the transformation the other elements. I tried this with the "IF" function. But always all elements are shown in the destination document. Do you have any suggestions, how to solve this problem?

Here is a screenshot of my modeled function

 

best regards

Hi Ralf,

Did your issue get resolved?

This looks like a tricky requirement. Easiest way I can think of would be to achieve this with two mappers in succession. the first one will convert the Sync to a Process. And the second one takes the same document as input and delivers the same as output expect removing the attribute you don't need. This can be achieved using an advanced mapper where you write the XSLT code.



To do this in your code, You would need an empty template that removes the Original document attribute and then an identity template that copies everything else in to the output.



Some thing like the code below.. (I assumed the attribute is called OriginalDocument. If not use the exact string after @ in '@OriginalDocument'



<xsl:stylesheet version="1.0" xmlns:xsl="www.w3.org/.../Transform">

<!--empty template that removes Original document attribute.-->

<xsl:template match="@OriginalDocument" />

<!--identity template copies everything forward by default-->

<xsl:template match="@*|node()"&gt;

<xsl:copy>

<xsl:apply-templates select="@*|node()"/&gt;

</xsl:copy>

</xsl:template>

</xsl:stylesheet>



When you have more questions on xslt syntax, you can search the internet more on how to remove certain attributes from an element using xslt. Hope this helps.
