Holen Sie die Details von SOAP xml Antwort

Question

Ich analysiere unter SOAP-Antwort mit Xmltodict-Bibliothek.

Hier ist mein Code die erforderlichen Details aus der SOAP-Antwort zu erhalten:

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 
          [doorway + 'RoomTypes'] 
          [doorway + 'RoomType']) 
} 

    return_dict = { 
    'ibp': 'dbs', 
    'rL': sorted([ 
     { 
      'rtc': roomrate['@RoomTypeCode'], 
      'rpc': roomrate['@RatePlanCode'], 
      'rtn': names[roomrate['@RoomTypeCode']], 
      'rmt': rate['@AmountBeforeTax'], 
      'cur': _availability['@CurrencyCode'], 
      'ttc': float(rate['@AmountAfterTax']) - float(rate['@AmountBeforeTax']), 
      'egc': 0, 
      'long': '' 

     } 
     for _availability in availability 
     for roomrate in listify(_availability 
           [doorway + 'RoomRates'] 
           [doorway + 'RoomRate']) 
     for rate in listify(roomrate

     key=lambda x: float(x['rmt'])), 
    'hc': _availability['@HotelCode'], 
    'hn': '' 
} 

    return return_dict 

Ich bin in der Lage, die erforderlichen Daten aus der SOAP-Nachricht in das erforderliche Format von Wörterbuch zu erhalten . Aber, ich bekomme Problem, wenn ich die Details von dieser speziellen SOAP-Nachricht, die oben geteilt wird, bekomme. In allen anderen Fällen bekam ich nur die Antwort eines einzelnen Hotels mit einer unterschiedlichen Anzahl von Kombinationen, aber in dieser SOAP-Antwort habe ich zwei Hotels und mein Parsing-Code holt die Zimmerpreise von beiden Hotels gleichzeitig und es sortieren. Aber, ich möchte die Sortierung auf den ersten Hoteloptionen dann auf den zweiten Hoteloptionen tun. Die Anzahl der Hotels könnte variieren, versuchen Sie also eine generische Lösung anzubieten, die unabhängig von der Anzahl der Hotels funktioniert.

Jede Hilfe würde geschätzt werden. Vielen Dank!

Answer 1

Betrachten Sie die XML vereinfacht mit XSLT, die deklarative Programmiersprache verwendet speziell XML-Dokumente zu transformieren. Python kann XSLT 1.0 mit dem Modul lxml ausführen. Von dort analysieren Sie den transformierten Baum in ein Wörterbuch mit xmltodict, das weiter in json geparst werden kann. Alle drei Ausgänge sind im Folgenden enthalten:

XSLT Skript (Speichern als .xsl Datei, siehe unten in.py-Skript)

<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> 
    <rmt><xsl:value-of select="@AmountBeforeTax"/></rmt> 
    <cur><xsl:value-of select="ancestor::ns2:Availability/@CurrencyCode"/></cur> 
    <ttc><xsl:value-of select="@AmountAfterTax - @AmountBeforeTax"/></ttc> 
    <egc>0</egc> 
    <long></long> 
    </xsl:template> 

</xsl:transform> 

Python Script (Ausgänge zu xml, dict, und json Typen)

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

Sie erstellen Liste Verständnis von allen Zimmerpreis-Ergebnisse (obwohl alle Hotels), aber Hotelcode ist außerhalb einer Schleife aller Art, auf der gleichen Ebene wie die Liste. So erhalten Sie immer nur ein (letztes) der Hotels.

In Code:

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

Variable _availability ist das letzte Vorkommen von der vorhergehenden Schleife "für _availability in Verfügbarkeit". Es war die Schleife für Block "normal", es wäre dort nicht einmal definiert.

Meiner Meinung nach sind solche komplexen Datenstrukturen sehr schwer zu lesen und zu verwenden, vielleicht sollten Sie den OOP-Ansatz mit Daten in Objektattributen in Betracht ziehen.

Wenn Sie darauf bestehen, solche Datenstrukturen verwenden, können Sie es wie folgt tun:

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
