Subject: Re: [xsl] How to copy only the really existing <choice> branch/element? "value-of-if-exist" From: Martin Honnen <Martin.Honnen@xxxxxx> Date: Wed, 07 Oct 2009 14:18:51 +0200 |
Assume I have a XML source based on the following (simplified) XSD schema:
<xsd:element name="top" type="mytype"/>
<xsd:complexType name="mytype"> <xsd:choice> <xsd:element name="aaa" type="....."> <xsd:element name="bbb" type="....."> <xsd:element name="ccc" type="....."> </xsd:choice> </xsd:complexType>
That mean either element aaa or element bbb or element ccc is filled/exists.
Now I want to copy only this sub-element to a target which currently exists.
If I simply write:
<xsl:value-of select=".../aaa"/> <xsl:value-of select=".../bbb"/> <xsl:value-of select=".../ccc"/>
then ALL three elements were copied. The 2 branches which do not exist were created as empty elements so that the target XML doc looks like e.g.
<top> <aaa></aaa> <bbb>myvalue</bbb> <ccc></ccc> </top>
which is an invalid XML because of its XSD schema file definition.
