xsl-foファイルのタグを読み込んで置き換えます

Question

タグを見つけてjavaの.foファイルに置き換える必要があります。どうすればいいのか教えてください。私はいくつかの話題を読んだが、私はJavaで新しく、いくつかの問題を抱えている...このファイルでは、<fo:external-graphic src="url('Images/box.jpg')"/>というタグを見つけて、それをurl = "（別のパス）"に置き換えなければならない！

<fo:block font-weight="bold" space-before.optimum="12pt" space-after.optimum="12pt" padding="0.1in" border="thin solid black"> 
     The manufacturer declines every liability with regard to any direct or 
     consequential damage caused by the equipment to you, your body parts, 
     your personal belongings, your domestic animals e/o beloved relatives. 
     Use this equipment at your own risk, and let God protect your fingers! 
    </fo:block> 

    <fo:block space-before.optimum="6pt">Have fun with our stuff!</fo:block> 

    </fo:block><fo:block id="d0e81" text-align="justify" font="11pt Times" line-height="1.3" space-before.minimum="18pt" space-before.conditionality="retain">

    <fo:block space-before.optimum="6pt">

Answer 1

DOMを作成してからfo:external-graphicという要素をすべて取得します。 src属性を好きなものに変更することができます。

//parse the xml file 
Document doc = DocumentBuilderFactory.newInstance().newDocumentBuilder().parse(new File("file.xml")); 

//get all elements called fo:external-graphic 
NodeList list = doc.getElementsByTagName("fo:external-graphic"); 
for(int i = 0 ; i < list.getLength() ; i++){ 
    Element element = (Element)list.item(i); 
    NamedNodeMap attributes = element.getAttributes(); 

    //change the src attribute 
    Attr src = (Attr)attributes.getNamedItem("src"); 
    System.out.println(src.getValue()); 
    src.setValue("url('another/path/box.jpg')"); 
} 

//let's print out the resulting doc for debugging purposes 
OutputFormat format = new OutputFormat(doc); 
format.setLineWidth(65); 
format.setIndenting(true); 
format.setIndent(2); 
Writer out = new StringWriter(); 
XMLSerializer serializer = new XMLSerializer(out, format); 
serializer.serialize(doc); 
System.out.println(out.toString());
