XML解析Android中

Question

大家我在做XML解析像這樣

public class XMLHandler extends DefaultHandler{ 

// =========================================================== 
// Fields 
// =========================================================== 
static ArrayList<Category1> cat_list=new ArrayList<Category1>(); 
static ArrayList<Products> product_list=new ArrayList<Products>(); 
    Category1 cat; 
    Products pro; 
private boolean in_outertag = false; 
private boolean in_innertag = false; 
private boolean in_mytag = false; 
private boolean in_mytag1 = false; 
private boolean in_mytag2 = false; 
private boolean in_mytag3 = false; 


private XMLDataSet myParsedExampleDataSet = new XMLDataSet(); 

// =========================================================== 
// Getter & Setter 
// =========================================================== 

public XMLDataSet getParsedData() { 
     return this.myParsedExampleDataSet; 
} 

// =========================================================== 
// Methods 
// =========================================================== 
@Override 
public void startDocument() throws SAXException { 
     this.myParsedExampleDataSet = new XMLDataSet(); 
} 

@Override 
public void endDocument() throws SAXException { 
     // Nothing to do 
} 

/** Gets be called on opening tags like: 
    * <tag> 
    * Can provide attribute(s), when xml was like: 
    * <tag attribute="attributeValue">*/ 
@Override 
public void startElement(String namespaceURI, String localName, 
      String qName, Attributes atts) throws SAXException { 
     if (localName.equals("root")) { 
      this.in_outertag = true; 
     }else if (localName.equals("Categories")) { 
      this.in_innertag = true; 
     }else if (localName.equals("Category")) { 
      cat =new Category1(); 
      String attrValue = atts.getValue("id"); 
      int i = Integer.parseInt(attrValue); 
      myParsedExampleDataSet.setExtractedInt(i); 
      cat.setCatId(i+""); 
      //cat_id[i]=myParsedExampleDataSet.setExtractedInt(i); 
      //Log.i("id", cat.setCatId(i+"")); 
      String attrValue1 = atts.getValue("pid"); 
      int i1 = Integer.parseInt(attrValue1); 
      myParsedExampleDataSet.setExtractedInt(i1); 
      cat.setPid(i1+""); 
      //p_id[i1]=myParsedExampleDataSet.setExtractedInt(i1); 
      //Log.i("pid", myParsedExampleDataSet.setExtractedInt(i1)+""); 
      this.in_mytag = true; 
     }else if (localName.equals("title")) { 
      // Extract an Attribute 

      this.in_mytag1 = true; 
     }else if (localName.equals("products")) { 
      this.in_innertag = true; 
     }else if (localName.equals("product")) { 
      pro=new Products(); 
      String attrValue = atts.getValue("catid"); 
      int i = Integer.parseInt(attrValue); 
      myParsedExampleDataSet.setExtractedInt(i); 
      pro.setCatId(i+""); 
      //Log.i("catid", myParsedExampleDataSet.setExtractedInt(i)+""); 
      this.in_mytag = true; 
     }else if (localName.equals("name")) { 
      // Extract an Attribute 
      this.in_mytag2 = true; 
     }else if (localName.equalsIgnoreCase("url")) { 
      // Extract an Attribute 
      this.in_mytag3 = true; 
     } 
} 

/** Gets be called on closing tags like: 
    * </tag> */ 
@Override 
public void endElement(String namespaceURI, String localName, String qName) 
      throws SAXException { 
     if (localName.equals("root")) { 
      this.in_outertag = false; 
     }else if (localName.equals("Categories")) { 
      this.in_innertag = false; 
     }else if (localName.equals("Category")) { 
      cat_list.add(cat); 

      this.in_mytag = false; 
     }else if (localName.equals("title")) { 

      this.in_mytag1=false; 
     }else if (localName.equals("products")) { 

      this.in_innertag=false; 
    }else if (localName.equals("product")) { 
     product_list.add(pro); 
     this.in_mytag=false; 
    }else if (localName.equals("name")) { 

     this.in_mytag2=false; 
    }else if (localName.equalsIgnoreCase("url")) { 

     this.in_mytag3=false; 
    } 
} 

/** Gets be called on the following structure: 
    * <tag>characters</tag> */ 
@Override 
public void characters(char ch[], int start, int length) { 
     if(this.in_mytag1){ 
     myParsedExampleDataSet.setExtractedString(new String(ch, start, length)); 
     cat.setCatName(new String(ch, start, length)); 
} 
     if(this.in_mytag2){ 
      myParsedExampleDataSet.setExtractedString(new String(ch, start, length)); 
      pro.setProductId(new String(ch, start, length)); 
    } 
     if(this.in_mytag3){ 
      String chars = new String(ch, start, length); 
      chars = chars.trim(); 
      //myParsedExampleDataSet.setExtractedString(chars); 
      pro.setUrl(chars); 
    } 
} 

}

我解析所有的東西很好，但不是URL ....

XML文件是這樣的

<?xml version="1.0" encoding="UTF-16"?> 
<products> 

    <product catid="11"> 

     <name>song1</name> 

     <url>http://news.google.co.in/news?edchanged=1&amp;ned=en_il</url> 

    </product> 

我得到了結果ned=en_il只有

請幫幫我，我在哪裏錯了？ 謝謝x

Answer 1

您可以扭曲你的<url>節點到CDATA標籤這樣

<url><![CDATA[http://news.google.co.in/news?edchanged=1&ned=en_il]]></url> 

整頓問題嘗試。

Answer 2

我會推薦使用android.sax來解析它更容易。你可以閱讀在這裏http://www.ibm.com/developerworks/opensource/library/x-android/

Answer 3

該問題很可能出現在您的字符方法中。

對於給定的元素，可能會多次調用此方法，您的代碼假設它只會被調用一次。例如它很可能被稱爲「http://news.google.co.in」，「/ news？edchanged = 1 &」和「ned = en_il」

如果您將字符追加到適當的屬性而不是設置它們它可能會工作。
