Title: question about : xpathselector.selectSingleNode(doc)

You should check the element thats returned form selectSingleNode() - maybe it cannot be found and you're getting a NullPointerException.   Without a sample program and XML document its hard to know what the problem is....

All works well but I have a question about this point : I select an Element from its xpath address : The two parts of code are working : Element richText_Element =         (Element) xpoix_Element.selectSingleNode("richDesc[@type='product']/richText"); richText_Element = richText_Element.addText(rt + ", station : " + nb); or : DocumentFactory I_DocumentFactory = new DocumentFactory(); XPath xpath = I_DocumentFactory.createXPath("richDesc[@type='product']/richText"); Element richText_Element = (Element) xpath.selectSingleNode(xpoix_Element); richText_Element = richText_Element.addText(rt + ", station : " + nb); But when the element "richDesc[@type='product']/richText" is not present in the document, the program crashes without Exception... Is it normal or Is sth missing in my code ? Thank you for your help, Regards. François Paulus.
