java poi替换pptx中的文字

最近项目中有个需求，PPTS中的文字能够进行替换。比如在PPT中设置一个标志位“#year#”，用户能在界面上把这个标志位替换成自己所需要的值。
以下是我写的代码。
public void test4()
{
try
{
XMLSlideShow ppt = new XMLSlideShow( new FileInputStream("2.pptx") );

Pattern pyear = Pattern.compile( "([#]year[#])" ) ;
Matcher myear = null ;
Pattern pmonth = Pattern.compile( "([#]month[#])" ) ;
Matcher mmonth = null ;

for( XSLFSlide slide : ppt.getSlides() )
{
for( XSLFShape shape : slide.getShapes() )
{
// System.out.println( shape.getShapeName() + " " + shape.toString() ) ;

if ( shape instanceof XSLFTextShape )
{
XSLFTextShape txtshape = (XSLFTextShape)shape ;
System.out.println( "XSLFTextShape" + ":" + shape.getShapeName() + ":" + txtshape.getText() ) ;
//
if ( txtshape.getShapeName().equals("Text Box 14") )
{
txtshape.setText("fuck") ;
}

myear = pyear.matcher( txtshape.getText() ) ;
// mmonth = pmonth.matcher( txtshape.getText() ) ;
// System.out.println(myear.replaceAll("2011")) ;
// txtshape.setText( myear.replaceAll("2011") ) ;
// txtshape.setText( mmonth.replaceAll("09") ) ;
// System.out.println( txtshape.getTextParagraphs().get(0).getText() );
// System.out.println( txtshape.getTextParagraphs().get(0).getTextRuns().get(0).getText() ) ;

for ( XSLFTextParagraph p : txtshape.getTextParagraphs() )
{
// System.out.println( p.getText() ) ;
// System.out.println( p.getTextRuns().toString() ) ;
for ( XSLFTextRun textRun : p.getTextRuns() )
{
// System.out.println( textRun.getText() ) ;
}
}
}
else if ( shape instanceof XSLFConnectorShape )
{
XSLFConnectorShape connectorShape = (XSLFConnectorShape)shape ;
System.out.println( "XSLFConnectorShape" + ":" + shape.getShapeName() ) ;
}
else if ( shape instanceof XSLFPictureShape )
{
XSLFPictureShape picShape = (XSLFPictureShape)shape ;
System.out.println( "XSLFPictureShape" + ":" + shape.getShapeName() ) ;
}
}
}

FileOutputStream out = new FileOutputStream("3.pptx") ;
ppt.write( out ) ;
out.close() ;
}
catch (FileNotFoundException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
catch (IOException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
}

以上代码只是进行测试下方案是否可行，所以规范度什么的不会太高。现在有一个问题就是，如果ＰＰＴＸ中的文字外面还有套一层矩型框之类的东西，文字就无法替换。如果是用以下代码，则可以读取，但也没找到替换的办法。
public void test5()
{
try
{
XMLSlideShow ppt = new XMLSlideShow( new FileInputStream("2.pptx") );

for( XSLFSlide slide : ppt.getSlides() )
{
System.out.println( slide.getCommonSlideData().getDrawingText().size() ) ;
for ( DrawingTextBody drawingText : slide.getCommonSlideData().getDrawingText() )
{
for ( DrawingParagraph ph : drawingText.getParagraphs() )
{
System.out.println( ph.getText() ) ;
}
}

// for ( DrawingParagraph ph : slide.getCommonSlideData().getText() )
// {
// System.out.println( ph.getText() ) ;
// }
}
}
catch (FileNotFoundException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
catch (IOException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
}
