JSP, Solr - How to get attribute from node, add to documentbuilder and display on webpage.

[willie wright]

Hi,

I am having trouble learning how to get attributes from nodes and adding them to a documentbuilder object and making it available to display on the webpage. I am using results from Solr with Java and XML. (I'm new to Java but I'm good with JavaScript and JQuery.)

With this app I am having problems getting numFound from the XML response and showing it on the webpage. Here's an example of the XML response from Solr:

<?xml version="1.0" encoding="UTF-8"?>
<response>
<lst name="responseHeader">
 <int name="status">0</int>
 <int name="QTime">31</int>
 <lst name="params">
  <str name="indent">on</str>
  <str name="start">0</str>
  <str name="q">widget</str>
  <str name="rows">10</str>
  <str name="version">2.2</str>
 </lst>
</lst>
<result name="response" numFound="583" start="0">
 <doc>
  <str name="cgyid">14150</str>
...
  <float name="prc">19.97</float>
 </doc>

I really appreciate your assistance. Here's the code I'm working with:

/// Sends stuff to frontend
                request.setAttribute("resultsDoc", doc);
                if (doc != null)
                {
                    List<SearchResult> searchResults = convertDoc(doc);
                    request.setAttribute("searchResults", searchResults);

                    Map<String, Integer> facetCounts = getFacetCounts(doc);
                    request.setAttribute("facetCounts", facetCounts);

/// I tested this on the webpage and I can get this value from type                  
                    Element root = doc.createElement("sonnet");
                    request.setAttribute("type", "Shakespearean");
                
                   } 

/// Get value from XML

 private Element getNumRows(Document doc)
 {
     Element result = new HashMap<String, Integer>();
     NodeList numFound = doc.getElementsByTagName("numFound");
     if (numFound != null && numFound.getLength() > 0)
     {
         
     }
     return result;
 }

UseCodeTags because it will be easier to read your code.

It'd be easier if you helped us know where to look in the code, posted only the most-relevant sections, etc. 650+ lines of code is a lot to look over to find something so specific.

Hi, I have edited this post to be shorter. Installing a Java IDE helped.

I think I'm on the right track to a solution here. I just need some help putting it all together. Thanks!
