Hi Folks,
I just started using the "selectPath" Function of XmlBeans with a XPath-Expression and run into different problems.
I have a xml structure that can have arbitrary nestings of categories/category elements (see further below). With my Xpath expression I want to filter a node category with a certain default name and get all of its child categories.
But all I get Is the above mentioned exception:
java.lang.RuntimeException: net.sf.saxon.trans.DynamicError: Required item type of first operand of '/' is node(); supplied value has item type java:org.apache.xmlbeans.impl.store.Xobj-DocumentXobj
[...]
I searched with google and espacially in this forum but could not find any hint on this!
I use XmlBeans in combination with Spring and Maven. I have xmlbeans.jar:2.30, xmlbeans-xpath.jar:2.3.0, saxon.jar:8.7 and saxon-xpath.jar:8.7 in my classpath.
Thanks for any help!
Regards,
Christian
Here is the code that causes my problems:
[...]
String prefix = "declare namespace my='
http://www.my-namespace.com';";
String xq = prefix + "$this//my:category/@default_name='Category 1'";
myDocument.selectPath(xq);
[...]
The underlying xml is a little complex and looks like this:
<my:sites xmlns:my="
http://www.my-namepace.com">
<my:site default_name="My Test Site">
<my:attributes>
<my:attribute locale="de_DE">
<my:name>_longDescription_</my:name>
<my:value>Description of site</my:value>
</my:attribute>
</my:attributes>
<my:categories>
<my:category default_name="Root Category">
<my:attributes/>
<my:categories>
<my:category default_name="Category 1">
<my:attributes>
<my:attribute locale="de_DE">
<my:name>_longDescription_</my:name>
<my:value>Description of Category 1</my:value>
</my:attribute>
</my:attributes>
<my:categories>
