我需要你的帮助来解析XML宣布。
让我们看看下面的XML:
<?xml version="1.0" encoding="UTF-8"?>
<FAVORIS>
<LOGGED>1</LOGGED>
<NOTICES NUM_PAGE="2">
<NOTICE>
<DEPARTMENT>33</DEPARTMENT>
<SOURCE>EMP</SOURCE>
<OBJET><![CDATA[Fourniture d'une solution régionale]]></OBJET>
<ID_PROCEDURE>7543</ID_PROCEDURE>
<ORGANISME><![CDATA[Gcs]]></ORGANISME>
<TYPE_AVIS>ZZ</TYPE_AVIS>
<TYPE_PROCEDURE>W3</TYPE_PROCEDURE>
<CATEGORIE>Service</CATEGORIE>
<DATE_OFFRE>16/09/2013 12:00</DATE_OFFRE>
<DECALAGE_HORAIRE>0</DECALAGE_HORAIRE>
</NOTICE>
<NOTICE>
<DEPARTMENT>33</DEPARTMENT>
<SOURCE>EMP</SOURCE>
<OBJET><![CDATA[Refonte du portail]]></OBJET>
<ID_PROCEDURE>4323</ID_PROCEDURE>
<ORGANISME><![CDATA[Mairie de W]]></ORGANISME>
<TYPE_AVIS>Z</TYPE_AVIS>
<TYPE_PROCEDURE>W1</TYPE_PROCEDURE>
<CATEGORIE>Service</CATEGORIE>
<DATE_OFFRE>03/09/2013 12:00</DATE_OFFRE>
<DECALAGE_HORAIRE>0</DECALAGE_HORAIRE>
</NOTICE>
....
</NOTICES>
</FAVORIS>
为了解析这个XML,我遵循了http://developer.android.com/training/basics/network-ops/xml.html
中关于XML解析的教程当我解析这个XML时,我遇到如下错误:
expected: START_TAG {null}NOTICES (position:START_TAG <FAVORIS>@2:10 in java.io.InputStreamReader@40e69360)
这是由于要求但我该如何解决这个问题?
有关我的代码的更多信息:
public class AOThumbnail_ParserXML {
private static final String ns = null;
public ArrayList<AOThumbnail> parse(String in) throws XmlPullParserException, IOException {
Decoder decoder = new Decoder();
String decoded_in = decoder.decode(in);

parser.setFeature(XmlPullParser.FEATURE_PROCESS_NAMESPACES, true);
parser.setInput(new ByteArrayInputStream(decoded_in.getBytes()), null);
parser.nextTag();
return readFeed(parser);
}
private ArrayList<AOThumbnail> readFeed(XmlPullParser parser) throws XmlPullParserException, IOException {
ArrayList<AOThumbnail> entries = new ArrayList<AOThumbnail>();
parser.require(XmlPullParser.START_TAG, ns, "NOTICES");
while (parser.next() != XmlPullParser.END_TAG) {
if (parser.getEventType() != XmlPullParser.START_TAG) {
continue;
}
String name = parser.getName();
// Starts by looking for the entry tag
if (name.equals("NOTICE")) {
entries.add(readEntry(parser));
} else {
skip(parser);
}
}
return entries;
}

continue;
}
String name = parser.getName();
if (name.equals("ORGANISME")) {
organisme = read(parser, "ORGANISME");
} else if (name.equals("OBJET")) {
objet = read(parser, "OBJET");
} else if (name.equals("DATE_CAND")) {
date_candidature = read(parser, "DATE_CAND");
} else if (name.equals("DATE_OFFRE")) {

} else if (name.equals("ID_PROCEDURE")) {
idProcedure = read(parser, "ID_PROCEDURE");
} else if (name.equals("DECALAGE_HORAIRE")) {
decalageHoraire = read(parser, "DECALAGE_HORAIRE");
} else {
skip(parser);
}
}
String date = "";
try {
if (date_candidature.length() > 0)
date = date_candidature;
else if (date_offre.length() > 0)
date = date_offre;
else
date = "Se référer à l'annonce";
} catch (Exception ex) {
Logger.logit(ex);
}
return new AOThumbnail(organisme, objet, date, departement, idProcedure, source, Boolean.parseBoolean(decalageHoraire));
}
private String read(XmlPullParser parser, String balise) throws IOException, XmlPullParserException {
parser.require(XmlPullParser.START_TAG, ns, balise);
String content = readText(parser);
parser.require(XmlPullParser.END_TAG, ns, balise);
return content;
}
private String readText(XmlPullParser parser) throws IOException, XmlPullParserException {
String result = "";
if (parser.next() == XmlPullParser.TEXT) {
result = parser.getText();
parser.nextTag();
}
return result;
}
private void skip(XmlPullParser parser) throws XmlPullParserException, IOException {
if (parser.getEventType() != XmlPullParser.START_TAG) {
throw new IllegalStateException();
}
int depth = 1;
while (depth != 0) {
switch (parser.next()) {
case XmlPullParser.END_TAG:
depth--;
break;
case XmlPullParser.START_TAG:
depth++;
break;
}
}
}
}
如果我解析这样的XML(见下文),它可以工作,但不适用于上面的XML!

我希望你能帮助我, 非常感谢!
答案 0 :(得分:1)
在readFeed()方法中,您告诉您的Parser当前事件应该是名为“NOTICES”的START_TAG,在其他情况下,该方法将抛出一个Exception,这是您发布的。这就是第二个.xml文件工作的原因,但不是第一个(该文件的第一个事件是START_TAG,名称为“FAVORIS”)。
所以你应该用另一种方法来查找NOTICES块,你可以使用这样的东西(还有其他方法):
while (parser.next() != XmlPullParser.START_TAG && !(parser.getName().equals("NOTICES")));
因此,当while循环结束时,您的解析器将位于NOTICES块的开头。
PS:我没有测试代码,所以它可能不起作用,但解决方案应该类似。

使用require“FAVORIS”解决了问题!
private ArrayList<AOThumbnail> readFeed(XmlPullParser parser) throws XmlPullParserException, IOException {
ArrayList<AOThumbnail> entries = new ArrayList<AOThumbnail>();
//Go to FAVORIS' level
parser.require(XmlPullParser.START_TAG, ns, "FAVORIS");
while (parser.next() != XmlPullParser.END_TAG) {
if (parser.getEventType() != XmlPullParser.START_TAG) {
continue;
}
String name = parser.getName();
if(parser.getName().equals("NOTICES")) {
//Go to NOTICES' level
parser.require(XmlPullParser.START_TAG, ns, "NOTICES");
//Parse on Notices' level
return readFeed(parser);
}
// Starts by looking for the entry tag
if (name.equals("NOTICE")) {
Logger.logit("Dans notice !!!!!!");
entries.add(readEntry(parser));
} else {
skip(parser);
}
}
return entries;
}
感谢@ javi9375的提示;)
