Answer 2

与 Kaira 的回应类似，但侧重于 IndexValue 元素：

DocumentBuilderFactory documentBuilderFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder documentBuilder = documentBuilderFactory.newDocumentBuilder();
InputSource inputSource = new InputSource(new StringReader(xmlString));
Document document = documentBuilder.parse(inputSource);
XPathFactory xPathFactory = XPathFactory.newInstance();
XPath xpath = xPathFactory.newXPath();
XPathExpression expression = xpath.compile("//IndexValue/text()");
NodeList nodeList = (NodeList) expression.evaluate(document, XPathConstants.NODESET);

for (int n = 0; n < nodeList.getLength(); n++) {
    System.out.println(n + ": " + nodeList.item(n).getNodeValue());
}

如果你痴迷于简短的编码，那么它可能更合适（但不是我的风格:-)）

public class XMLTextExtractor {
    static String  val;

    public static void main(String[] args) {

        String textResult = "";
        for (String fragment: val.replace("<?xml version=\"1.0\"?>", "").split(">")){
            textResult += fragment.replaceAll("<\\/.*|<.*","").trim();
        }
        System.out.println(textResult);
    }

    static {
        val = "<?xml version=\"1.0\"?><NGOSearchDocumentExt_Input> \n" +
                "    <Option>NGOSearchDocumentExt</Option><CabinetName>INOMNUTDB</CabinetName> \n" +
                "    <UserDBId>468315129</UserDBId><SearchText></SearchText><Rank>Y</Rank> \n" +
                "    <SearchOnPreviousVersions>N</SearchOnPreviousVersions> \n" +
                "    <LookInFolder>0</LookInFolder><IncludeSubFolder>Y</IncludeSubFolder> \n" +
                "    <Name></Name><Owner></Owner><CreationDateRange></CreationDateRange> \n" +
                "    <ExpiryDateRange></ExpiryDateRange><AccessedDateRange> \n" +
