我正在尝试使用 Jsoup 获取字体信息。举个例子:
下面是我的代码:
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,我的输出将如下所示:
"<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,但如何提取所有类似的元素。
<b>Hello World</b>
, Testing
<i><b>Font </b></i>
Style
<i>Check</i>
非常感谢任何建议或引用。

最佳答案
如果只需要从文档中提取文本,则加上任意 <b>
或<i>
标签(根据您的示例),请考虑使用 Whitelist 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);
它将输出(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());
}
