我使用Xpath提供的'evaluate'函數解析xml字符串以讀取嵌入在xml中特定標記中的內容。但是我在試圖解析一個嵌入到我想要解析的一組標籤中的xml時遇到了麻煩。使用XPath解析另一個xml中嵌入的xml Spring

在上面的xml示例中，我需要讀取和檢索標記「param」中的所有內容。 目前，我首先得到了param標記的計數，然後循環直通他們在標籤內獲得數據 -
paramCount = XPathUtils.evaluate(originalPayload,"count(/Channel/parameters/param)",XPathUtils.STRING);
for(int i=1;i<=pCount;i++){
pList.add(XPathUtils.evaluate(originalPayload, "/Channel/parameters/param[" +i+ "]",XPathUtils.STRING)
}
這工作得很好與其他個XML但與上面給出的樣本。我得到下面的錯誤 - 「？xmlversion =」？
"[Fatal Error] :5:17:The processing instruction target matching "[xX][mM][lL]" is not allowed."
如果我刪除了部分1.0" 編碼= 「UTF-8」 它解析標籤，但輸出 -
org.springframework.messaging.MessageHandlingException: HTTP request execution failed for URI [https://nike-dev.coupahost.com/api/suppliers?return_object=limited]; nested exception is org.springframework.web.client.HttpClientErrorException: 400 Bad Request
Unable to find valid PaymentTerm record for payment_term with keys {"code"=>"9999"}. Possible keys are ["id", "code"]. Please verify your xml.

因此，大家可以看到，它只是捕獲的各種標籤內的內容並打印它。 我問的是打印的所有文本在

所以預期輸出 -
