Also, if we use different streams instances without instantiating
the XMLStreamingXPath, looks like the previous the result got appended to
the second evaluated value.
String exampleXML =
"<?xml version=\"1.0\" encoding=\"ISO-8859-1\"?>\n" +
"\n" + " <getQuote>\n" +
" <request>\n" +
" <symbol>kasun</symbol>\n" +
" </request>\n" +
" </getQuote>";
String exampleXML2 =
"<?xml version=\"1.0\" encoding=\"ISO-8859-1\"?>\n" +
"\n" + " <getQuote>\n" +
" <request>\n" +
" <symbol>kasun</symbol>\n" +
" </request>\n" +
" </getQuote>";
InputStream inputStream = new
ByteArrayInputStream(exampleXML.getBytes());
String xpathString = "/getQuote/request/symbol";
XMLStreamingXPath xmlStreamingXPath = new XMLStreamingXPath();
xmlStreamingXPath.setXpathQuery(xpathString);
String val1 = (String)xmlStreamingXPath.getValueOf(inputStream);
String val2 = (String) xmlStreamingXPath.getValueOf(new
ByteArrayInputStream(exampleXML2.getBytes()));
System.out.println("Val " + val1);
System.out.println("Val " + val2);
--- output --
Val <symbol>kasun</symbol>
Val <symbol>kasun</symbol><symbol>kasun</symbol>
