There is an invalid signature error

[bcs018]

Hello, I'm trying to validate the XML, from the EFD Reinf, from the Federal Revenue of Brazil, but I'm told that the signature is invalid.
I already use this library in other XML signatures and it signs normally, but in this specific case I am not succeeding, follow the XML and the code PHP.:

<?xml version="1.0" encoding="utf-8"?> <Reinf xmlns="http://www.reinf.esocial.gov.br/schemas/envioLoteEventosAssincrono/v1_00_00"> <envioLoteEventos> <ideContribuinte> <tpInsc>1</tpInsc> <nrInsc>xxxxxx970</nrInsc> </ideContribuinte> <eventos> <evento Id="IDxxxxxxxxxxxxxxxxx023082110493200003"> <Reinf xmlns="http://www.reinf.esocial.gov.br/schemas/evt4020PagtoBeneficiarioPJ/v2_01_02"> <evtRetPJ id="IDxxxxxxxxxxxxxxxxx023082110493200003"> <ideEvento> <indRetif>1</indRetif> <perApur>202x-06</perApur> <tpAmb>2</tpAmb> <procEmi>1</procEmi> <verProc>2.1.02</verProc> </ideEvento> <ideContri> <tpInsc>1</tpInsc> <nrInsc>xxxxxx970</nrInsc> </ideContri> <ideEstab> <tpInscEstab>1</tpInscEstab> <nrInscEstab>7xxxxxxxxx0111</nrInscEstab> <ideBenef> <cnpjBenef>xxxxxxxxxx0100</cnpjBenef> <idePgto> <natRend>xxx01</natRend> <infoPgto> <dtFG>20xx-0x-xx</dtFG> <vlrBruto>xxxx98,60</vlrBruto> <retencoes> <vlrBaseIR>xxx8,60</vlrBaseIR> </retencoes> </infoPgto> </idePgto> <idePgto> <natRend>xxxx2</natRend> <infoPgto> <dtFG>20xx-0x-1x</dtFG> <vlrBruto>xxx,08</vlrBruto> <retencoes> <vlrBaseCSLL>xxx,08</vlrBaseCSLL> <vlrCSLL>6,00</vlrCSLL> <vlrBaseCofins>7xxx,08</vlrBaseCofins> <vlrCofins>x,00</vlrCofins> <vlrBasePP>xxxx,08</vlrBasePP> <vlrPP>x,00</vlrPP> </retencoes> </infoPgto> <infoPgto> <dtFG>20xxx-0x-x0</dtFG> <vlrBruto>6xxx,86</vlrBruto> <retencoes> <vlrBaseIR>xxx3,86</vlrBaseIR> <vlrIR>1x,10</vlrIR> </retencoes> </infoPgto> </idePgto> <idePgto> <natRend>xxxx03</natRend> <infoPgto> <dtFG>20xx-0x-x0</dtFG> <vlrBruto>38xx0,06</vlrBruto> <retencoes> <vlrBaseIR>3xxx,06</vlrBaseIR> </retencoes> </infoPgto> </idePgto> <idePgto> <natRend>xxxx19</natRend> <infoPgto> <dtFG>20xx-0x-1x</dtFG> <vlrBruto>1xxx,00</vlrBruto> <retencoes> <vlrBaseCSLL>1xxx0,00</vlrBaseCSLL> <vlrCSLL>xxx,00</vlrCSLL> <vlrBaseCofins>1xxx0,00</vlrBaseCofins> <vlrCofins>9xx,50</vlrCofins> <vlrBasePP>xxx0,00</vlrBasePP> <vlrPP>xx,25</vlrPP> </retencoes> </infoPgto> <infoPgto> <dtFG>20xx-xx-2x</dtFG> <vlrBruto>xxxx0,00</vlrBruto> <retencoes> <vlrBaseCSLL>xxx0,00</vlrBaseCSLL> <vlrCSLL>xx,00</vlrCSLL> <vlrBaseCofins>xx00,00</vlrBaseCofins> <vlrCofins>xx,00</vlrCofins> <vlrBasePP>xxx0,00</vlrBasePP> <vlrPP>xx,00</vlrPP> </retencoes> </infoPgto> <infoPgto> <dtFG>20xx-xx-xx</dtFG> <vlrBruto>xx00,00</vlrBruto> <retencoes> <vlrBaseCSLL>xx00,00</vlrBaseCSLL> <vlrCSLL>2xxx,00</vlrCSLL> <vlrBaseCofins>xx00,00</vlrBaseCofins> <vlrCofins>xx0,00</vlrCofins> <vlrBasePP>xx00,00</vlrBasePP> <vlrPP>xx0,00</vlrPP> </retencoes> </infoPgto> <infoPgto> <dtFG>20xx-0x-x0</dtFG> <vlrBruto>xxx,00</vlrBruto> <retencoes> <vlrBaseIR>3x00,00</vlrBaseIR> <vlrIR>x5,00</vlrIR> </retencoes> </infoPgto> </idePgto> </ideBenef> </ideEstab> </evtRetPJ> </Reinf> </evento> </eventos> </envioLoteEventos> </Reinf>

I need to sign the XML in the tag that is inside Reinf, the signature must be inside the Reinf tag:

Can someone help me please

You give us a whole lot of info, but you tell us nothing about the exact error you are getting...

[bcs018]

the error is that the signature is not validating, it is saying that the signature is invalid

look at the lines:

$serviceresponse_node = $xmlDocument->getElementsByTagName("evtRetPJ")->item(0);
$serviceresponse_node2 = $xmlDocument->getElementsByTagNameNS('http://www.reinf.esocial.gov.br/schemas/evt4020PagtoBeneficiarioPJ/v2_01_02', '*')->item(0);

Is that right?,, $serviceresponse_node is the content I want to sign, and $serviceresponse_node2 is where I want to put the signature
