我试图将由xsl文件转换的xml数据显示在
Android应用程序的webview中.但是,数据未按预期显示.
XML file used (cdcatalog_with_xsl.xml) -- Sample xml data
--------------------------------------
<?xml version="1.0" encoding="ISO-8859-1"?>
<?xml-stylesheet type="text/xsl" href="cdcatalog.xsl"?>
<!-- Edited by XMLSpy® -->
<catalog>
<cd>
<title>Empire Burlesque</title>
<artist>Bob Dylan</artist>
<country>USA</country>
<company>Columbia</company>
<price>10.90</price>
<year>1985</year>
</cd>
<cd>
<title>Hide your heart</title>
<artist>Bonnie Tyler</artist>
<country>UK</country>
<company>CBS Records</company>
<price>9.90</price>
<year>1988</year>
</cd>
</catalog>
XSL file used (cdcatalog.xsl) -- Sample xsl file
-----------------------------
<?xml version="1.0" encoding="ISO-8859-1"?>
<!-- Edited by XMLSpy® -->
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
<html>
<body>
<h2>My CD Collection</h2>
<table border="1">
<tr bgcolor="#9acd32">
<th>Title</th>
<th>Artist</th>
</tr>
<xsl:for-each select="catalog/cd">
<tr>
<td><xsl:value-of select="title"/></td>
<td><xsl:value-of select="artist"/></td>
</tr>
</xsl:for-each>
</table>
</body>
</html>
</xsl:template>
</xsl:stylesheet>
有些人会帮我提供示例代码,将这些数据加载到Android应用的webview中吗？
它非常棘手,我试着让它易于理解.请按照以下步骤_
原文链接：https://www.f2er.com/xml/292159.html>在res / raw下构建您的XSLT文件,
>要么解析你的XML,要么准备好你的XML(res / raw)
>最后,使用这些消息在Android Webview中显示
你的cdcatalog_with_xsl.xml& cdcatalog.xsl必须在res / raw中.我已经构建了LoadXSLTinWebview来满足您的需求_
public class LoadXSLTinWebview extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
getWindow().requestFeature(Window.FEATURE_PROGRESS);
WebView webview = new WebView(this);
setContentView(webview);
//Reading XSLT
String strXSLT = GetStyleSheet(R.raw.cdcatalog);
//Reading XML
String strXML = GetStyleSheet(R.raw.cdcatalog_with_xsl);
/*
* Loading XSLT...
*/
//Transform ...
String html=StaticTransform(strXSLT,strXML);
//Loading the above transformed CSLT in to Webview...
webview.loadData(html,"text/html",null);
}
/*
* Transform XSLT to HTML string
*/
public static String StaticTransform(String strXsl,String strXml) {
String html = "";
try {
InputStream ds = null;
ds = new ByteArrayInputStream(strXml.getBytes("UTF-8"));
Source xmlSource = new StreamSource(ds);
InputStream xs = new ByteArrayInputStream(strXsl.getBytes("UTF-8"));
Source xsltSource = new StreamSource(xs);
StringWriter writer = new StringWriter();
Result result = new StreamResult(writer);
TransformerFactory tFactory = TransformerFactory.newInstance();
Transformer transformer = tFactory.newTransformer(xsltSource);
transformer.transform(xmlSource,result);
html = writer.toString();
ds.close();
xs.close();
xmlSource = null;
xsltSource = null;
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
} catch (TransformerConfigurationException e) {
e.printStackTrace();
} catch (TransformerFactoryConfigurationError e) {
e.printStackTrace();
} catch (TransformerException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}
return html;
}
/*
* Read file from res/raw...
*/
private String GetStyleSheet(int fileId) {
String strXsl = null;
InputStream raw = getResources().openRawResource(fileId);
ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
int size = 0;
// Read the entire resource into a local byte buffer.
byte[] buffer = new byte[1024];
try {
while ((size = raw.read(buffer,1024)) >= 0) {
outputStream.write(buffer,size);
}
raw.close();
strXsl = outputStream.toString();
Log.v("Log","xsl ==> " + strXsl);
} catch (IOException e) {
e.printStackTrace();
}
return strXsl;
}
}
输出：
我希望这对所有人都有帮助！
