我在XML中使用Processing语言。我在这里找到了一个类似的问题:How to find certain items in an xml?。但这个问题尚未得到解答。无论如何,我想知道,当我得到XML文件的结果时,如何在其中搜索某个字符串?我使用.getChildren()
功能进行搜索吗?返回了很多字符串,但我想搜索某个字符串。
答案 0 :(得分:0)
您可以在parseXML() 2.0:
中使用ProcessingString data = "<mammals><animal>Goat</animal></mammals>";
void setup() {
XML xml = parseXML(data);
if (xml == null) {
println("XML could not be parsed.");
} else {
XML firstChild = xml.getChild("animal");
println(firstChild.getContent());
}
}
// Sketch prints:
// Goat
另请参阅Processing 2.0 XML示例和方法。
// The following short XML file called "mammals.xml" is parsed
// in the code below. It must be in the project's "data" folder.
//
// <?xml version="1.0"?>
// <mammals>
// <animal id="0" species="Capra hircus">Goat</animal>
// <animal id="1" species="Panthera pardus">Leopard</animal>
// <animal id="2" species="Equus zebra">Zebra</animal>
// </mammals>
XML xml;
void setup() {
xml = loadXML("mammals.xml");
XML[] children = xml.getChildren("animal");
for (int i = 0; i < children.length; i++) {
int id = children[i].getInt("id");
String coloring = children[i].getString("species");
String name = children[i].getContent();
println(id + ", " + coloring + ", " + name);
}
}
// Sketch prints:
// 0, Capra hircus, Goat
// 1, Panthera pardus, Leopard
// 2, Equus zebra, Zebra
