First, I must say that I find \[code\]Xpath\[/code\] as a very nice parser , and I guess pretty powerful when comparing it to other parsers .Given the following code :\[code\] DocumentBuilderFactory domFactory = DocumentBuilderFactory.newInstance(); domFactory.setNamespaceAware(true); DocumentBuilder builder = domFactory.newDocumentBuilder(); Document doc = builder.parse("input.xml"); XPath xpath = XPathFactory.newInstance().newXPath();\[/code\]If I wanted to find the \[code\]first\[/code\] node of Round 1 & Door 1 , here : \[code\]<Game> <Round> <roundNumber>1</roundNumber> <Door> <doorName>abd11</doorName> <Value> <xVal1>0</xVal1> <xVal2>25</xVal2> <pVal>0.31</pVal> </Value> <Value> <xVal1>25</xVal1> <xVal2>50</xVal2> <pVal>0.04</pVal> </Value> <Value> <xVal1>50</xVal1> <xVal2>75</xVal2> <pVal>0.19</pVal> </Value> <Value> <xVal1>75</xVal1> <xVal2>100</xVal2> <pVal>0.46</pVal> </Value> </Door> <Door> <doorName>vvv1133</doorName> <Value> <xVal1>60</xVal1> <xVal2>62</xVal2> <pVal>1.0</pVal> </Value> </Door> </Round> <Round> <roundNumber>2</roundNumber> <Door> <doorName>eee</doorName> <Value> <xVal1>0</xVal1> <xVal2>-25</xVal2> <pVal>0.31</pVal> </Value> <Value> <xVal1>-25</xVal1> <xVal2>-50</xVal2> <pVal>0.04</pVal> </Value> <Value> <xVal1>-50</xVal1> <xVal2>-75</xVal2> <pVal>0.19</pVal> </Value> <Value> <xVal1>-75</xVal1> <xVal2>-100</xVal2> <pVal>0.46</pVal> </Value> </Door> <Door> <doorName>cc</doorName> <Value> <xVal1>-60</xVal1> <xVal2>-62</xVal2> <pVal>0.3</pVal> </Value> <Value> <xVal1>-70</xVal1> <xVal2>-78</xVal2> <pVal>0.7</pVal> </Value> </Door> </Round></Game>\[/code\]I'll do this : \[code\] XPathExpression expr = xpath.compile("//Round[1]/Door[1]/Value[1]/*/text()"); Object result = expr.evaluate(doc, XPathConstants.NODESET); NodeList nodes = (NodeList) result;\[/code\]and if I wanted the \[code\]second\[/code\] node of Round 1 & Door 1 then : \[code\]XPathExpression expr = xpath.compile("//Round[1]/Door[1]/Value[2]/*/text()"); \[/code\]but how do I do this using a loop , since I don't know how much \[code\]Value-nodes\[/code\] I have , meaning how can I do this using a loop , where each iteration I retrieve 3 (I mean the \[code\]xVal1\[/code\] , \[code\]xVal2\[/code\] and \[code\]pVal\[/code\] values ) more values of a Value node !? The reasons for asking for this are :[*]I don't know how much \[code\]Round\[/code\]-s I have[*]I don't know how much \[code\]Value\[/code\]-s I have[*]I don't want to declare every time a new \[code\]XPathExpression\[/code\] Thanks .
