我的传入SOAP消息的格式如下:
const soap = `
<?xml version="1.0" encoding="UTF-8"?>
<env:Envelope xmlns:env="http://www.w3.org/2003/05/soap-envelope">
<env:Header/>
<env:Body property="def">
<Root>
<Abc attr="abc">123456</Abc>
</Root>
</env:Body>
</env:Envelope>
`;
我期望得到的是<env:Body>
的内容不变:
<Root>
<Abc attr="abc">123456</Abc>
</Root>
要提取身体,我使用简单的正则表达式:
function getSoapBody(xmlStr) {
let soapBody = null;
if (xmlStr) {
const soapBodyRegex = /<env:Body>([\s\S]*)<\/env:Body>/im;
const soapBodyRegexMatchResult = xmlStr.match(soapBodyRegex);
soapBody = soapBodyRegexMatchResult[1];
}
return soapBody;
}
然而,当然,获取正则表达式的身体并不理想。
此外,我不想重新发明轮子,我正在寻找一个基本上getSoapBody的解决方案(甚至是npm包),无论使用什么前缀(如果前缀改变,上面的正则表达式会失败)或者如果有的话是可选属性等。

您可以使用xml2js解析:
var xml2js = require('xml2js');
var builder = new xml2js.Builder();
const soap = `
<?xml version="1.0" encoding="UTF-8"?>
<env:Envelope xmlns:env="http://www.w3.org/2003/05/soap-envelope">
<env:Header/>
<env:Body optional="abc">
<Root>
<Abc attr="1">123456</Abc>
</Root>
</env:Body>
</env:Envelope>
`;
var options = {explicitArray: false, tagNameProcessors: [xml2js.processors.stripPrefix] };
xml2js.parseString(soap, options, (err, result) => {
if (err) {
console.log('An error has occurred: ' + err);
return;
}
// Get the soap body object
var soapBody = result.Envelope.Body;
// Remove optional attribute(s) from <Body> element.
if (soapBody.$) {
delete soapBody.$;
}
// Get the body XML if needed
var soapBodyXML = builder.buildObject(soapBody);
console.log(soapBodyXML);
});

我使用fast-xml-parser(https://www.npmjs.com/package/fast-xml-parser/v/2.9.0)通过使用以下选项来排除命名空间和前缀并确保属性位于节点“ attr”下来实现此目的:
async function stripBodyFromSoapEnvelope(inputBody){
const xmlParser = require('fast-xml-parser');
let options = {
attributeNamePrefix : '',
attrNodeName: 'attr',
ignoreNameSpace: true,
ignoreAttributes: false
};
const soapenv = xmlParser.parse(inputBody,options);
return(soapenv.Envelope.Body);
}
希望这会有所帮助。
