Name	Description
VOTable	VOTable input (not the file path but the table itself)
Version	VOTable version (1.1, 1.2, ...). Default value is "1.2"
XPath	Normal XPath as if it would be used with normal XMLs

XPath_From_VOTables_core	localworker	Where all the magic happens Script import org.dom4j.; import org.dom4j.io.SAXReader; import org.dom4j.xpath.; SAXReader reader = new SAXReader(false); reader.setIncludeInternalDTDDeclarations(false); reader.setIncludeExternalDTDDeclarations(false); XPath xpathObj = new DefaultXPath(xpath); HashMap map = new HashMap(); map.put(abbrevation,namespace); xpathObj.setNamespaceURIs(map); Document document = reader.read(new StringReader(xmltext)); List nodelist = xpathObj.selectNodes(document); // Process the elements in the nodelist ArrayList outputList = new ArrayList(); ArrayList outputXmlList = new ArrayList(); String val = null; String xmlVal = null; for (Iterator iter = nodelist.iterator(); iter.hasNext();) { Node element = (Node) iter.next(); xmlVal = element.asXML(); val = element.getStringValue(); if (val != null && !val.equals("")) { outputList.add(val); outputXmlList.add(xmlVal); } } List nodelist=outputList; List nodelistAsXML=outputXmlList;
abbrevation_value	stringconstant	Value h
namespace	stringconstant	Value http://www.ivoa.net/xml/VOTable/
namespace_version	beanshell	Script to join the namespace and the version input. Unless version 1.1 specified it will output the VOTable namespace for version 1.2 Script if (version != "1.1") { version = "1.2"; } namespace = namespace_url + "v" + version;
XPath_modifier	beanshell	Simple regex to change the XPath in such way so it works for XPathFromVOTables core. Script xpath_out = "/"+xpath_in.replaceAll("/(?=\\w)","/h:"); //"(?i)(?
