使用SOAP :: Lite解析XML响应

Question

使用SOAP::Lite我正在尝试解析XML响应；但是，SOAP :: SOM没有给我想要的值。它似乎采取了与我尝试查找的路径不同的路径。

    #!/usr/bin/env perl
    use strict;
    use warnings;
    use SOAP::Lite;
    use Data::Dumper;

    my $xml  = <<'__XML__';
    <S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/">
      <S:Body>
        <GetResponse>

    </S:Envelope>
    __XML__

    my $som = SOAP::Deserializer->deserialize($xml);

    print Dumper($som->valueof('//services/common-data/subscription-list/'));

我正在使用不同的XML路径获取相同ID的值。

我想从请求的XML路径中获取其余ID的<key>，例如beta和gamma。

从<number>元素获取所有日期的xpath表达式：

//services/common-data//subscription//number/text()

[仅从<number>内的<subscription-list>内的<default-subscription/>元素中获取数据，请使用：

//services/common-data//subscription[.//child::*[name()='default-subscription']]//number/text()
