SOAP応答から必要な詳細情報を取得するための私のコードです：

def listify(obj): 
"""To convert each element of SOAP into a list, so processing of response would be easy.""" 
if isinstance(obj, list): 
    return obj 
return [obj] 


def search_hotels_formatted_response(soap): 
    """Parse the response.""" 
    soap = xmltodict.parse(soap, process_namespaces=True) 

    # Deal with namespaces 
    env = 'http://schemas.xmlsoap.org/soap/envelope/:' 
    doorway = 'http://www.derbysoft.com/doorway:' 

    availability = listify(
    soap[env + 'Envelope'] 
     [env + 'Body'] 
     [doorway + 'MultiAvailabilityResponse'] 
     [doorway + 'Availabilities'] 
     [doorway + 'Availability']) 

    # Intermediate data structure to hold room names 
    names = { 
    roomtype['@RoomTypeCode']: roomtype['@RoomTypeName'] 
    for _availability in availability 
    for roomtype in listify(_availability

私は辞書の必要な形式にSOAPメッセージから必要な詳細情報を取得することができています。しかし、私は上で共有されたこの特定のSOAPメッセージから詳細を取得する際に問題を抱えています。他のすべてのケースでは、私はちょうどそれの組み合わせの異なる数を持つ単一のホテルの応答を得ていたが、このSOAP応答で私は2つのホテルがあり、私の解析コードは、両方のホテルの部屋の価格を同時に取得しているそれをソートします。しかし、私はセコングホテルのオプションで最初のホテルのオプションでソートをしたい。ホテルの数は様々である可能性があるので、ホテルの数に関係なく機能する一般的なソリューションを提供してください。

すべてのヘルプが評価されます。ありがとう！

XSLT、XML文書を変換するために特に使用宣言型プログラミング言語を使用してXMLを簡素化することを検討してください。 Pythonはlxmlモジュールを使用してXSLT 1.0を実行できます。そこから、変換された木をxmltodictという辞書に構文解析し、さらにjsonに構文解析することができます。以下の3つの出力はすべて以下に含まれます。

XSLTスクリプト（以下の.xslファイルとして保存されます）。PYスクリプト）

<xsl:transform xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0" 
       xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" 
       xmlns:ns2="http://www.derbysoft.com/doorway"> 
<xsl:output version="1.0" encoding="UTF-8" indent="yes" /> 
<xsl:strip-space elements="*"/> 

    <!-- Response Level --> 
    <xsl:template match="ns2:MultiAvailabilityResponse"> 
    <Responses>  
     <xsl:apply-templates select="ns2:Availabilities"/> 
    </Responses> 
    </xsl:template> 

    <xsl:template match="ns2:Availabilities"> 
    <xsl:apply-templates select="ns2:Availability"> 
     <xsl:sort select="@CurrencyCode" order="descending"/> 
    </xsl:apply-templates>  
    </xsl:template> 

    <!-- Hotel Level --> 
    <xsl:template match="ns2:Availability">  
    <Hotel>  
     <xsl:apply-templates select="ns2:RoomRates"/> 
    </Hotel> 
    </xsl:template> 

    <!-- Room Rates Level --> 
    <xsl:template match="ns2:RoomRates">   
    <xsl:apply-templates select="ns2:RoomRate">   
     <xsl:sort select="descendant::ns2:Rate/@AmountBeforeTax" 
       order="ascending" data-type="number"/> 
    </xsl:apply-templates>  
    </xsl:template> 

    <!-- Room Rate Level --> 
    <xsl:template match="ns2:RoomRate"> 
    <RoomRate>  
     <ibp>dbs</ibp> 
     <rL><xsl:apply-templates select="ns2:Rates"/></rL> 
     <hc><xsl:value-of select="ancestor::ns2:Availability/@HotelCode"/></hc> 
     <hn></hn> 
    </RoomRate> 
    </xsl:template> 

    <!-- Rates Level --> 
    <xsl:template match="ns2:Rates/*">  
    <xsl:variable name="rtc" select="ancestor::ns2:RoomRate/@RoomTypeCode"/> 
    <rtc><xsl:value-of select="$rtc"/></rtc> 
    <rpc><xsl:value-of select="ancestor::ns2:RoomRate/@RatePlanCode"/></rpc> 
    <rtn><xsl:value-of select="ancestor::ns2:Availability/ns2:RoomTypes/ 
           ns2:RoomType[@RoomTypeCode=$rtc]/@RoomTypeName"/></rtn>

    <egc>0</egc> 
    <long></long> 
    </xsl:template> 

</xsl:transform> 

のPythonスクリプト（XML、辞書、およびJSONタイプに出力）

import lxml.etree as ET 
import xmltodict 
import json 

# LOAD XML AND XSL 
dom = ET.parse('soap.xml') 
xslt = ET.parse('XSLTScript.xsl') 

# TRANSFORM 
transform = ET.XSLT(xslt) 
newdom = transform(dom) 

# NEW TREE OUTPUT 
return_xml = ET.tostring(newdom, encoding='UTF-8', pretty_print=True, xml_declaration=True) 
print(return_xml.decode("utf-8")) 

return_dict = xmltodict.parse(return_xml) 
print(return_dict) 

return_json = json.dumps(return_dict, indent=4) 
print(return_json)

Answer 2

すべての客室料金の結果からリストの理解を作成していますが、ホテルコードはリストと同じレベルのループの外にあります。 それで、あなたはいつもホテルの1つだけを得るでしょう。コードで

：

'hc': _availability['@HotelCode'], 

変数_availabilityは "可用性に_availabilityための" 前のループの最後の出現です。ループはブロックのために「普通」でした、それはそこで定義されることさえありませんでした。

私の意見では、このような複雑なデータ構造は読み込みと使用が非常に難しく、オブジェクトの属性のデータでOOPアプローチを検討する必要があります。

あなたは、このようなデータ構造を使用して主張する場合、あなたはこのようにそれを行うことができます。

def search_hotels_formatted_response(soap): 
    """Parse the response.""" 
    soap = xmltodict.parse(soap, process_namespaces=True) 

    # Deal with namespaces 
    env = 'http://schemas.xmlsoap.org/soap/envelope/:' 
    doorway = 'http://www.derbysoft.com/doorway:' 

    availability = listify(
    soap[env + 'Envelope'] 
     [env + 'Body'] 
     [doorway + 'MultiAvailabilityResponse'] 
     [doorway + 'Availabilities'] 
     [doorway + 'Availability']) 

    # Intermediate data structure to hold room names 
    names = { 
    roomtype['@RoomTypeCode']: roomtype['@RoomTypeName'] 
    for _availability in availability 
    for roomtype in listify(_availability 
          [doorway + 'RoomTypes'] 
          [doorway + 'RoomType']) 
} 

    # Intermediate data structure to hold rates 
    rates = { 
    rate['@RoomTypeCode']: rate 
    for _availability in availability 
    for rate in listify(_availability 
          [doorway + 'RoomRates'] 
          [doorway + 'RoomRate']) 
} 

    return_list = [] 
    for _availability in availability: 
     return_list.append({ 
    'ibp': 'dbs', 
    'rL': sorted([ 
     { 
      'rtc': rates[roomtype['@RoomTypeCode']]['@RoomTypeCode'], 
      'rpc': rates[roomtype['@RoomTypeCode']]['@RatePlanCode'], 
      'rtn': names[rates[roomtype['@RoomTypeCode']]['@RoomTypeCode']], 
      'rmt': rates[roomtype['@RoomTypeCode']][doorway + 'Rates'][doorway + 'Rate']['@AmountBeforeTax'], 
      'cur': _availability['@CurrencyCode'], 
      'ttc': float(rates[roomtype['@RoomTypeCode']][doorway + 'Rates'][doorway + 'Rate']['@AmountAfterTax']) - float(rates[roomtype['@RoomTypeCode']][doorway + 'Rates'][doorway + 'Rate']['@AmountBeforeTax']), 
      'egc': 0, 
      'long': '', 
     } 
     for roomtype in listify(_availability 
          [doorway + 'RoomTypes'] 
          [doorway + 'RoomType'])], 
     key=lambda x: float(x['rmt'])), 
    'hc': _availability['@HotelCode'], 
    'hn': '' 
}) 

    return return_list
