XMLTokenizeLanguage on camel split EIP

Question

我有一個關於XMLTokenizeLanguage的問題，更具體地說是關於XMLTokenExpressionIterator.java ：

this.splitpath接受以“/”分隔的多個標記。

我嘗試以這種方式使用它：==>

.split(body().xtokenize("/ns1:[some type]/ns1:[another type]" 'i', ns))
    .streaming()

其中 ns 和 ns1 是命名空間

但管道中沒有結果

你能和我分享更多關於XMLTokenizeLanguage的內容嗎？

駱駝網站中的示例是關於將 XML 拆分為 1 種 [JAXB java POJO]，那么 2 種或更多類型 [JAXB java POJO] 呢？ 有可能嗎？

這是我的 XML 內容：

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<LocationMessages xmlns="http://standards.iso.org/iso/15143/-3">
    <Links>
        <rel>self</rel>
        <href>https://[source domain name ]/public/api/aemp/v2/15143/-3/Fleet/Equipment/ID/[equipement id]/Locations/2021-01-01T00:00/2022-09-28T09:34:06.439553/1</href>
    </Links>
    <Links>
        <rel>last</rel>
        <href>https://[source domain
            name]/public/api/aemp/v2/15143/-3/Fleet/Equipment/ID/[equipement
            id]/Locations/2021-01-01T00:00/2022-09-
            28T09:34:06.439553/1</href>
    </Links>
    <Location datetime="2022-04-05T09:52:53Z">
        <Latitude>43.290143</Latitude>
        <Longitude>5.491987</Longitude>
        <Altitude>102.375</Altitude>
        <AltitudeUnits>metre</AltitudeUnits>
    </Location>
    <Location datetime="2022-05-04T13:50:57Z">
        <Latitude>43.289926</Latitude>
        <Longitude>5.492582</Longitude>
        <Altitude>77.0</Altitude>
        <AltitudeUnits>metre</AltitudeUnits>
    </Location>
</LocationMessages>

這是命名空間聲明：

Namespaces ns = new Namespaces("ns1", "http://standards.iso.org/iso/15143/-3");

這是 xtokenize 語言定義的拆分：

.split(body().xtokenize("/ns1:Links/ns1:Location", 'i', ns)).streaming()

當我一次使用一種類型（鏈接或位置）時，拆分 xtokenize 對我有用，但我不想使用 (.multicast()) 來復制管道。

我想通過 2 種類型（鏈接和位置）進行標記化，然后應用內容路由 EIP (choice()) 為每種標記類型選擇路由。

鏈接和位置是 xjc 從 xsd 模式生成的 JAXB pojo 類型。 這里簡要介紹一下它們的結構：

Answer 1

您需要使用通配符*更改xtokenize表達式以根據其模式定義包含其所有潛在子項，即Links和Location 。

split的正確代碼應該是.split(body().xtokenize("/ns1:LocationMessages/ns1:*", 'i', ns)).streaming()
