将html标记存储在xml中 [英] Store html tags in xml
本文介绍了将html标记存储在xml中的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我有一个具有html格式和各种html标签的字符串.我想将此字符串放在xml标记中，以便html标记保留.例如
I have a String having html format with various html tags. I want to put this string in xml tags such that the html tags stay. e.g.
public class XMLfunctions {
public final static Document XMLfromString(String xml){
Document doc = null;
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
try {
DocumentBuilder db = dbf.newDocumentBuilder();
InputSource is = new InputSource();
is.setCharacterStream(new StringReader(xml));
doc = db.parse(is);
} catch (ParserConfigurationException e) {
System.out.println("XML parse error: " + e.getMessage());
return null;
} catch (SAXException e) {
System.out.println("Wrong XML file structure: " + e.getMessage());
return null;
} catch (IOException e) {
System.out.println("I/O exeption: " + e.getMessage());
return null;
}
return doc;
}
/** Returns element value
* @param elem element (it is XML tag)
* @return Element value otherwise empty String
*/
public final static String getElementValue( Node elem ) {
Node kid;
if( elem != null){
if (elem.hasChildNodes()){
for( kid = elem.getFirstChild(); kid != null; kid = kid.getNextSibling() ){
if( kid.getNodeType() == Node.TEXT_NODE ){
return kid.getNodeValue();
}
}
}
}
return "";
}
/*Start Parsing Body */
public static String getBodyXML(String id){
String line = null;
try {
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost("http://192.168.1.44:9090/solr/core0/select/?q=content_id:"+id+"&version=2.2&start=0&rows=10&indent=on");
HttpResponse httpResponse = httpClient.execute(httpPost);
HttpEntity httpEntity = httpResponse.getEntity();
line = EntityUtils.toString(httpEntity);
} catch (UnsupportedEncodingException e) {
line = "<results status=\"error\"><msg>Can't connect to server</msg></results>";
} catch (MalformedURLException e) {
line = "<results status=\"error\"><msg>Can't connect to server</msg></results>";
} catch (IOException e) {
line = "<results status=\"error\"><msg>Can't connect to server</msg></results>";
}
String st= ParseXMLBodyNode(line,"doc");
return st;
}
public static String ParseXMLBodyNode(String str,String node){
String xmlRecords = str;
String results = "";
String[] result = new String [1];
StringBuffer sb = new StringBuffer();
StringBuffer text = new StringBuffer();
try {
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
InputSource is = new InputSource();
is.setCharacterStream(new StringReader(xmlRecords));
Document doc = db.parse(is);
NodeList indiatimes1 = doc.getElementsByTagName(node);
sb.append("<results count=");
sb.append("\"1\"");
sb.append(">\r\n");
for (int i = 0; i < indiatimes1.getLength(); i++) {
Node node1 = indiatimes1.item(i);
if (node1.getNodeType() == Node.ELEMENT_NODE) {
Element element = (Element) node1;
NodeList nodelist = element.getElementsByTagName("str");
Element element1 = (Element) nodelist.item(0);
NodeList title = element1.getChildNodes();
title.getLength();
for(int j=0; j<title.getLength();j++){
text.append(title.item(j).getNodeValue());
}
System.out.print((title.item(0)).getNodeValue());
sb.append("<result>\r\n");
sb.append("<body>");
String tmpText = html2text(text.toString());
sb.append("<![CDATA[<body>");
sb.append(tmpText);
sb.append("</body>]]>");
sb.append("</body>\r\n");
sb.append("</result>\r\n");
result[i] = title.item(0).getNodeValue();
}
}
sb.append("</results>");
} catch (Exception e) {
System.out.println("Exception........"+results );
e.printStackTrace();
}
return sb.toString();
}
/*End Parsing Body*/
public static int numResults(Document doc){
Node results = doc.getDocumentElement();
int res = -1;
try{
res = Integer.valueOf(results.getAttributes().getNamedItem("count").getNodeValue());
}catch(Exception e ){
res = -1;
}
return res;
}
public static String getValue(Element item, String str) {
NodeList n = item.getElementsByTagName(str);
return XMLfunctions.getElementValue(n.item(0));
}
public static String html2text(String html) {
String pText = Jsoup.clean(html, Whitelist.basic());
return pText;
}
}
我称这些功能为
String xml = XMLfunctions.getBodyXML(id);
Document doc = XMLfunctions.XMLfromString(xml);
我希望字体标签作为xml中的html标签存在.
i want that the font tag be there as html tag in xml.
我们将不胜感激！!!!!!!
help would be appreciated!!!!!
推荐答案
将HTML包含在 CDATA部分，因此它不会被视为XML的一部分，而是普通文本:
Enclose your HTML in a CDATA section so it doesn't get treated as part of your XML, but instead just normal text:
<result>
<![CDATA[
<body><font size="2px" face="arial">Hello World</font></body>
]]>
</result>
更新
您的问题可能在这里:
sb.append("<result>\r\n");
sb.append("<body>");
String tmpText = html2text(text.toString());
sb.append("<![CDATA[<body>");
sb.append(tmpText);
sb.append("</body>]]>");
sb.append("</body>\r\n");
sb.append("</result>\r\n");
注意 sb.append(< body>"); 和 sb.append(</body> \ r \ n"); 行围绕您的CDATA部分，它们可能导致XML无法正确读取的问题.也许您应该删除这两行，使其看起来像这样:
Notice the sb.append("<body>"); and sb.append("</body>\r\n"); lines surrounding your CDATA section, they're probably causing the problem with your XML not being read correctly. Maybe you should remove those two lines so it looks like this:
sb.append("<result>\r\n");
String tmpText = html2text(text.toString());
sb.append("<![CDATA[<body>");
sb.append(tmpText);
sb.append("</body>]]>");
sb.append("</result>\r\n");
