I’m having a problem with SAX XML parser.
It Does parse everything, except quotation marks (“).
For example, if the text is hell"3o in a node, the result is hell.
Here are my codes:
XML Handler:
public class MyXMLHandler extends DefaultHandler {
Boolean currentElement = false;
String currentValue = null;
public static SitesList sitesList = null;
public static SitesList getSitesList() {
return sitesList;
}
public static void setSitesList(SitesList sitesList) {
MyXMLHandler.sitesList = sitesList;
}
/** Called when tag starts ( ex:- <name>AndroidPeople</name>
* -- <name> )*/
@Override
public void startElement(String uri, String localName, String qName,
Attributes attributes) throws SAXException {
currentElement = true;
if (localName.equals("channel"))
{
/** Start */
sitesList = new SitesList();
} else if (localName.equals("item")) {
String attr=attributes.getValue("item");
sitesList.setItem(attr);
} else if (localName.equals("title")) {
/** Get attribute value */
String attr = attributes.getValue("title");
sitesList.setTitle(attr);
}
else if (localName.equals("link")) {
/** Get attribute value */
String attr = attributes.getValue("link");
sitesList.setLink(attr);
}
else if (localName.equals("description")) {
/** Get attribute value */
String attr = attributes.getValue("description");
sitesList.setDescription(attr);
}
else if (localName.equalsIgnoreCase("pubDate")) {
/** Get attribute value */
String attr = attributes.getValue("pubDate");
sitesList.setPubDate(attr);
}
}
/** Called when tag closing ( ex:- <name>AndroidPeople</name>
* -- </name> )*/
@Override
public void endElement(String uri, String localName, String qName)
throws SAXException {
currentElement = false;
/** set value */
if (localName.equalsIgnoreCase("item"))
sitesList.setItem(currentValue);
else if (localName.equalsIgnoreCase("title"))
sitesList.setTitle(currentValue);
else if (localName.equalsIgnoreCase("link"))
sitesList.setLink(currentValue);
else if (localName.equalsIgnoreCase("description"))
sitesList.setDescription(currentValue);
else if (localName.equalsIgnoreCase("pubDate"))
sitesList.setPubDate(currentValue);
}
/** Called to get tag characters ( ex:- <name>AndroidPeople</name>
* -- to get AndroidPeople Character ) */
@Override
public void characters(char[] ch, int start, int length)
throws SAXException {
if (currentElement) {
currentValue = new String(ch, start, length);
currentElement = false;
}
}
}
Getter and Setter:
import java.util.ArrayList;
/** Contains getter and setter method for variables */
public class SitesList {
/** Variables */
private ArrayList<String> title = new ArrayList<String>();
private ArrayList<String> link = new ArrayList<String>();
private ArrayList<String> description = new ArrayList<String>();
private ArrayList<String> pubDate = new ArrayList<String>();
private ArrayList<String> item=new ArrayList<String>();
/** In Setter method default it will return arraylist
* change that to add */
public ArrayList<String> getTitle() {
return title;
}
public void setTitle(String title) {
this.title.add(title);
}
public ArrayList<String> getLink() {
return link;
}
public void setLink(String link) {
this.link.add(link);
}
public ArrayList<String> getDescription() {
return description;
}
public void setDescription(String description) {
this.description.add(description);
}
public ArrayList<String> getPubDate() {
return this.pubDate;
}
public void setPubDate(String PubDate) {
this.pubDate.add(PubDate);
}
public ArrayList<String> getItem() {
return this.item;
}
public void setItem(String item) {
this.item.add(item);
}
}
And RSS Thread class:
public class RssThread {
private String title,html,pubDate;
public RssThread(String title,String html,String pubDate)
{
this.title=title;
this.html=html;
this.pubDate=CovertToDate(pubDate);
}
private String CovertToDate(String pubDate) {
// TODO Auto-generated method stub
//Wed, 28 Sep 2011 11:40:51//
String newDate="";
if (pubDate.substring(0,pubDate.indexOf(",")).equals("Sun"))
newDate+="יום ראשון";
else if (pubDate.subSequence(0, pubDate.indexOf(",")).equals("Mon"))
newDate+="יום שני";
else if (pubDate.subSequence(0, pubDate.indexOf(",")).equals("Tue"))
newDate+="יום שלישי";
else if (pubDate.subSequence(0, pubDate.indexOf(",")).equals("Wed"))
newDate+="יום רביעי";
else if (pubDate.subSequence(0, pubDate.indexOf(",")).equals("Thu"))
newDate+="יום חמישי";
else if (pubDate.subSequence(0, pubDate.indexOf(",")).equals("Fri"))
newDate+="יום שישי";
else if (pubDate.subSequence(0, pubDate.indexOf(",")).equals("Sat"))
newDate+="יום שבת";
newDate+=", ";
String[] splited = pubDate.split(" ");
newDate += splited[1]+".";
if (splited[2].equals("Jan"))
newDate+="1.";
else if (splited[2].equals("Feb"))
newDate+="2.";
else if (splited[2].equals("Mar"))
newDate+="3.";
else if (splited[2].equals("Apr"))
newDate+="4.";
else if (splited[2].equals("May"))
newDate+="5.";
else if (splited[2].equals("Jun"))
newDate+="6.";
else if (splited[2].equals("Jul"))
newDate+="7.";
else if (splited[2].equals("Aug"))
newDate+="8.";
else if (splited[2].equals("Sep"))
newDate+="9.";
else if (splited[2].equals("Oct"))
newDate+="10.";
else if (splited[2].equals("Nov"))
newDate+="11.";
else if (splited[2].equals("Dec"))
newDate+="12.";
newDate+=splited[3];
newDate+=", בשעה "+splited[4].substring(0,splited[4].lastIndexOf(":"));
return newDate;
}
public String getTitle() {
return this.title;
}
public String getHTML() {
return html;
}
public String getPubDate() {
return this.pubDate;
}
}
I have forgotten to put another class:
public class XMLParsingExample {
private static String[] RssString;
/** Create Object For SiteList Class */
SitesList sitesList = null;
/** Called when the activity is first created. */
/** Create a new textview array to display the results */
String[] title;
String[] link;
String[] pubDate;
{
try {
/** Handling XML */
SAXParserFactory spf = SAXParserFactory.newInstance();
SAXParser sp = spf.newSAXParser();
XMLReader xr = sp.getXMLReader();
/** Send URL to parse XML Tags */
URL sourceUrl = new URL(
"http://www.blich.co.il/rss.xml");
/** Create handler to handle XML Tags ( extends DefaultHandler ) */
MyXMLHandler myXMLHandler = new MyXMLHandler();
xr.setContentHandler(myXMLHandler);
xr.parse(new InputSource(sourceUrl.openStream()));
} catch (Exception e) {
System.out.println("XML Pasing Excpetion = " + e);
}
/** Get result from MyXMLHandler SitlesList Object */
sitesList = MyXMLHandler.sitesList;
/** Assign textview array lenght by arraylist size */
title = new String[sitesList.getTitle().size()];
link = new String[sitesList.getTitle().size()];
pubDate = new String[sitesList.getTitle().size()];
/** Set the result text in textview and add it to layout */
RssString=new String[sitesList.getItem().size()/2];
for (int i=0;i<RssString.length;i++)
RssString[i]="";
int counter=1;
for (int i = 0; i < sitesList.getItem().size(); i++) {
if (i%2!=0) {
title[i-counter]=sitesList.getTitle().get(i);
if (title[i-counter]!=null)
RssString[i-counter]+=title[i-counter]+"~";
link[i-counter]=sitesList.getLink().get(i);
if (link[i-counter]!=null)
RssString[i-counter]+=link[i-counter]+"~";
pubDate[i-counter]=sitesList.getPubDate().get(i);
if (pubDate[i-counter]!=null)
RssString[i-counter]+=pubDate[i-counter]+"~";
counter++;
}
}
}
public static String[] getRSSarray() {
return RssString;
}
}
I gave you all the codes so you can see everything.
Maybe what both of you told me would work, but it would be complicated.
I have found an easier and more simple solution:
Other parser.
It uses 1 class (vs the sax parser that uses 3 classes), much much easier to understand, and of course, doesn’t ignore quotation marks 😀
Thanks anyway.
