私はこのようなxmlを持っています:
<order>
<orderheader>
<orderissuedate>1/11/2013</orderissuedate>
</orderheader>
</order>
INFO で設定されたミュール ロガー コンポーネントには、orderissuedate 1/11/2013 を出力しようとするミュール式があります。
私は次の表現を使用します。
[xpath('/order/orderheader//orderissuedate')] は機能しませんでした。
私も試しました: #[xpath('/order/orderheader/orderissuedate/text()').text] これも機能しませんでした。
正しい xpath 式を教えてください。次のエラー メッセージが表示されます。
java.lang.RuntimeException: org.mule.api.MuleRuntimeException: XPath 式の評価に失敗しました: "/Order/OrderHeader/OrderIssueDate/text()"
オンラインの xpath チェッカーを使用してこれらの xpath 式をテストしたところ、動作するようです。ご協力いただきありがとうございます。
元のxmlは次のとおりです。
<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE Order>
<Order
xmlns:core="rrn:org.xcbl:schemas/xcbl/v4_0/core/core.xsd"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<OrderHeader>
<OrderNumber>
<BuyerOrderNumber>111111</BuyerOrderNumber>
</OrderNumber>
<OrderIssueDate>2013-06-28T08:40:12</OrderIssueDate>
<OrderReferences>
<AccountCode>
<core:RefNum></core:RefNum>
</AccountCode>
</OrderReferences>
</OrderHeader>
</Order>
およびラバからのエラー出力:
