Re: [Vtd-xml-users] How to traverse to nodes from current node after evalXPath?

[<cra...@co...>]

I don't think vtd-xml is intended for html unless it is xhtml... 

if it is an XML file.. could you provide an example of the data, just to remove ambiguity?

Subject: [Vtd-xml-users] How to traverse to nodes from current node after evalXPath? 

Hi, 
I am using vtd-xml to parse html.  The structure of html is unknown until run-time.  After I used xpath to locate the <p> that I want, I want to find <img>s that matches certain src are inside the <p>, before the <p> or after <p>.  How?  Thanks. 


    VTDNav vn = vg.getNav();     
    AutoPilot ap = new AutoPilot (vn);   

      try { 
    ap.selectXPath ("//p[matches(.,'[\\p{Space}\\p{Punct}]" + term + "[\\p{Space}\\p{Punct}]'"); 
      } catch (com.ximpleware.XPathParseException e) { 
      } 

      try { 
    while ((j = ap.evalXPath ()) != -1) { // loop through all matching <p> 
      try { 
            if (vn.toString (j).split (" ").length >= MIN_NUM_WORDS_IN_SNIPPET) {// if word count in this paragraph is larger than the minimum, I found the paragraph.  Otherwise, continue to loop 
          sbSnippet.append (vn.toString (j)); 
              break; 
        } 
        } catch (com.ximpleware.NavException e) { 
      } 
        } 
      } catch (com.ximpleware.XPathEvalException e) { 
      } catch (com.ximpleware.NavException e) { 
      } 

      // find whether <img>s with matched src are inside <p>, before <p> or after <p> 
      // How? 
    
      ap.resetXPath ();
