Question

我正在尝试使用Jsoup获取字体信息。举个例子： Sample font

以下是我的代码：

result = rtfToHtml(new StringReader(streamToString((InputStream)contents.getTransferData(dfRTF))));
                // Example of text extraction from html
                // Parse html
                // String test = result.toString();
                Document doc = Jsoup.parse(result);
                // Select first bold text
                String strdoc = doc.toString();
                String words[] = strdoc.split("font-family");
                Element firstBoldElt = doc.select("b").first(); 
                Elements ele = doc.select("body");
                String test = ele.toString();
                Elements all = doc.select("b");
                String boldtext = all.text();

通过使用代码我的输出如下：

"<body> 
 <p class="default">
     <span style="color: #000000; font-size: 21pt; font-family: MyriadPro-Bold;">
         <b>Hello World</b>
     </span>
     <span style="color: #000000; font-size: 21pt; font-family: MyriadPro-Bold;">, Testing</span> 
     <span style="color: #000000; font-size: 21pt; font-family: MyriadPro-Bold;">
         <i><b>Font </b></i>
     </span>
     <span style="color: #000000; font-size: 21pt; font-family: MyriadPro-Bold;"> Style</span>
     <span style="color: #000000; font-size: 21pt; font-family: MyriadPro-Bold;">
         <i>Check</i>
     </span>
     <span style="color: #000000; font-size: 10pt; font-family: MyriadPro-Bold;"></span>
</p>   
</body>"

我可以提取第一个 BOLD 元素或所有 BOLD 元素，但我怎么能像所有这些元素相似。

<b>Hello World</b>
, Testing
<i><b>Font </b></i>
 Style 
<i>Check</i>

Answer 1

如果您只需要从文档中提取文本，以及任何<b>或<i>标记（根据您的示例），请考虑使用白名单类（请参阅docs）：

String html = "<body><p class='default'> <span style='color: #000000; font-size: 21pt; font-family: MyriadPro-Bold;'> <b>Hello World</b> </span> <span style='color: #000000; font-size: 21pt; font-family: MyriadPro-Bold;'> , Testing </span> <span style='color: #000000; font-size: 21pt; font-family: MyriadPro-Bold;'> <i><b>Font </b></i> </span> <span style='color: #000000; font-size: 21pt; font-family: MyriadPro-Bold;'> Style </span> <span style='color: #000000; font-size: 21pt; font-family: MyriadPro-Bold;'> <i>Check</i> </span> <span style='color: #000000; font-size: 10pt; font-family: MyriadPro-Bold;'> </span> </p></body>";

Whitelist wl = Whitelist.simpleText();
wl.addTags("b", "i"); // add additional tags here as necessary
String clean = Jsoup.clean(html, wl);
System.out.println(clean);

将输出（根据您的示例）：

11-07 19:04:45.738: I/System.out(318): <b>Hello World</b>   , Testing   
11-07 19:04:45.738: I/System.out(318): <i><b>Font </b></i>   Style   
11-07 19:04:45.738: I/System.out(318): <i>Check</i>

更新

ArrayList<String> elements = new ArrayList<String>();

Elements e = doc.select("span");

for (int i = 0; i < e.size(); i++) {
    elements.add(e.get(i).html());
}

Answer 2

您需要将选择器更改为<p>标记，如下所示：
Element all = doc.select("p").first();

然后你需要得到那个元素的所有孩子。

String myString = "";
for(Element item : all.children()) {
    myString += item.text();
}

我假设你想要标签内的文字，而不是标签本身。

或者你也可以。

Elements all = doc.select("b");
all.addAll(doc.select("i"));
all.addAll(doc.select("span"));
String myString = all.text();
