I try to read a XML File with Ximpleware. My Problem is, that I don't find usefull examples or tutorials.
I want to read following XML:
<title name="bliblablu">
<program>
<text lang="1">
<![CDATA[English]]>
</text>
<text lang="2">
<![CDATA[Francais]]>
</text>
<text lang="3">
<![CDATA[Deutsch]]>
</text>
</program>
<program>
<text lang="1">
<![CDATA[Afrikans]]>
</text>
<text lang="2">
<![CDATA[Portuges]]>
</text>
<text lang="3">
<![CDATA[Italiano]]>
</text>
</program>
</title>
And what I want is a simple print out like below.
1: English 2: Francais 3: Deutsch 1: Afrikans 2: Portuges 3: Italiano
How can I do this? I read the following SO Answer, SO Answer. And I tried with the following Code, but it does not work.
import com.ximpleware.AutoPilot;
import com.ximpleware.NavException;
import com.ximpleware.VTDGen;
import com.ximpleware.VTDNav;
import com.ximpleware.XPathEvalException;
import com.ximpleware.XPathParseException;
...
final VTDGen vg = new VTDGen();
vg.parseFile(file.getAbsolutePath(), false);
VTDNav vn = vg.getNav();
final AutoPilot ap = new AutoPilot(vn);
ap.selectXPath("/title/program/text");
Log.d(ap.evalXPathToString());
int i = 0, j = 0;
String languageNr = "", languageText ="";
while ((i = ap.evalXPath()) != -1) {
j = vn.getAttrVal("lang");
// z = vn.toNormalizedString(i);
if (j != -1) {
languageNr = vn.toString(j);
AutoPilot ap2 = new AutoPilot(vn);
ap2.resetXPath();
ap2.selectXPath("/ticker/program/text");
ap2.selectElement(Integer.toString(j));
languageText = ap2.evalXPathToString();
}
Log.d(languageNr);
Log.d(languageText);
}
My output is:
1: English 2: English 3: English 1: English 2: English 3: English
Thanks for every kind of help Lukas
Ok, I assume you know xpath reasonably well... so I don't see why you need another AutoPilot... Here is the first version.
import com.ximpleware.*;
public class simpleRead {
public static void main(String s[]) throws VTDException{
VTDGen vg = new VTDGen();
if (!vg.parseFile("d:\\xml\\title.xml", false)){
return;
}
VTDNav vn = vg.getNav();
AutoPilot ap = new AutoPilot(vn);
ap.selectXPath("/title/program/text/text()");
int i=0;
while((i=ap.evalXPath())!=-1){
System.out.print(" "+vn.toString(i));
}
}
}
Here is the second version that does the same thing...
import com.ximpleware.*;
public class simpleRead {
public static void main(String s[]) throws VTDException{
VTDGen vg = new VTDGen();
if (!vg.parseFile("d:\\xml\\title.xml", false)){
return;
}
VTDNav vn = vg.getNav();
AutoPilot ap = new AutoPilot(vn);
ap.selectXPath("/title/program/text");
int i=0;
while((i=ap.evalXPath())!=-1){
int k=vn.getText();
if (k!=-1)
System.out.print(" "+vn.toString(k));
}
}
}
