-----------------------------------------------------------
Finally, the PPT embedded files.
I found that the reason why I can't get the embedded object is that i can't get
the exembed object when the program executes to
org.apache.poi.hslf.usermodel.hslfobjectshape.getObjectData.
so, i modified the code.
{code:java}
package org.apache.poi.hslf.usermodel;
public final class HSLFObjectShape extends HSLFPictureShape implements
ObjectShape<HSLFShape,HSLFTextParagraph> {
......
private ExEmbed getExEmbed(boolean create) {
if (_exEmbed == null) {
......
int id = getObjectID() + 3;
for (Record ch : lst.getChildRecords()) {
if(ch instanceof ExEmbed){
ExEmbed embd = (ExEmbed)ch;
if( embd.getExOleObjAtom().getObjStgDataRef() == id) {
_exEmbed = embd;
}
}
}
......
}
return _exEmbed;
}
......
} {code}
then，i got the exembed ppt,pptx,doc,docx,xls,xlsx from ppt.
but , i cant got exembed txt,pdf,xml from ppt.
so,i modified the code again.
{code:java}
package org.apache.tika.parser.microsoft;
public class HSLFExtractor extends AbstractPOIFSExtractor {
......
private void handleSlideEmbeddedResources(ShapeContainer shapeContainer,
XHTMLContentHandler xhtml) throws TikaException, SAXException, IOException {
...... if
(!mediaType.equals("application/x-tika-msoffice-embedded; format=comp_obj") &&
!mediaType.equals("application/x-tika-msoffice") &&
!mediaType.equals("application/x-tika-msoffice-embedded; format=ole10_native"))
{
this.handleEmbeddedResource(stream, objID, objID,
mediaType, xhtml, false);
}
......
}
......
}
{code}
omg,I succeeded.
