Remove node from xml javascript

Please provide a concise and complete example, preferably as stand-alone HTML file.

Please also rephrase your question: "html collection xml"
Is it HTML or XML?

you need to lookup for a path to that node, once you got this path/criteria in your mind, you can create a "query" to point that node and remove it from the xml document

please send me the code to make it clear for me
thank you

for more details
i have a xml file
var m_XML_segments_Grid =  ($.parseXML(m_result_segments_Grid); where m_result_segments_Grid is an string
and m_XML_segments_Grid_str = new XMLSerializer().serializeToString(m_XML_segments_Grid);
contain the below :
"<NewDataSet>↵  <DsResQuery>↵    <SEQ>2</SEQ>↵    <SEGMENTNBRE>Segment #1</SEGMENTNBRE>↵    <P_SEGID>1</P_SEGID>↵    <CBOIN>08:00</CBOIN>↵    <CBOOUT>13:00</CBOOUT>↵    <DATE_TIME_STR>09/02/2019</DATE_TIME_STR>↵    <P_DESC>Segment 1 desc</P_DESC>↵    <P_DSCHEMA>8</P_DSCHEMA>↵    <P_WRKSTAT>0</P_WRKSTAT>↵    <P_PRESENT>1</P_PRESENT>↵    <P_STATUS_DAY>0</P_STATUS_DAY>↵    <P_FLOAT>0</P_FLOAT>↵  </DsResQuery>↵  <DsResQuery>↵    <SEQ>3</SEQ>↵    <SEGMENTNBRE>Segment #2</SEGMENTNBRE>↵    <P_SEGID>2</P_SEGID>↵    <CBOIN>14:00</CBOIN>↵    <CBOOUT>17:30</CBOOUT>↵    <DATE_TIME_STR>09/02/2019</DATE_TIME_STR>↵    <P_DESC>Segment 2 desc</P_DESC>↵    <P_DSCHEMA>8</P_DSCHEMA>↵    <P_WRKSTAT>0</P_WRKSTAT>↵    <P_PRESENT>1</P_PRESENT>↵    <P_STATUS_DAY>0</P_STATUS_DAY>↵    <P_FLOAT>0</P_FLOAT>↵  </DsResQuery>↵</NewDataSet>"

i need to add row to this xml
and delete row from this xml where SEQ = 1
i need to update the row where SEQ = 1 with new information
how to do that ?

what code? I believe the issue is in the request itself :
without knowing exactly where's the node to remove or from what criteria you remove the node, you CAN'T do it, it just random code.

I need to add row to this xml

i supposed you mean a <DsResQuery> node

and delete row from this xml where SEQ = 1

so delete a <DsResQuery>  having a children SEQ = 1

I need to update the row where SEQ = 1 with new information

after deleting, no need to update, you insert, before, it's an update

how to do that ?

please confirm above

yes you are right
this is exactly what i want

I need to add row to this xml

// new row
var newDsResQuery = "<DsResQuery>↵    <SEQ>2</SEQ>↵    <SEGMENTNBRE>Segment #1</SEGMENTNBRE>↵    <P_SEGID>1</P_SEGID>↵    <CBOIN>08:00</CBOIN>↵    <CBOOUT>13:00</CBOOUT>↵    <DATE_TIME_STR>09/02/2019</DATE_TIME_STR>↵    <P_DESC>Segment 1 desc</P_DESC>↵    <P_DSCHEMA>8</P_DSCHEMA>↵    <P_WRKSTAT>0</P_WRKSTAT>↵    <P_PRESENT>1</P_PRESENT>↵    <P_STATUS_DAY>0</P_STATUS_DAY>↵    <P_FLOAT>0</P_FLOAT>↵  </DsResQuery>↵";
// insert now
$("NewDataSet", m_XML_segments_Grid).append(newDsResQuery);

Select allOpen in new window

and delete row from this xml where SEQ = 1

var SEQ_value = "1";
$("NewDataSet DsResQuery SEQ", m_XML_segments_Grid).filter(function() { return $(this).text()==SEQ_value; }).remove();

Select allOpen in new window

I need to update the row where SEQ = 1 with new information

var CBOIN_new_hour = "11:09";
var SEQ_value = "1";
$("NewDataSet DsResQuery SEQ", m_XML_segments_Grid).filter(function() { return $(this).text()==SEQ_value; }).parent().find("CBOIN").text($("NewDataSet DsResQuery SEQ", m_XML_segments_Grid).filter(function() { return $(this).text()==SEQ_value; }));

Select allOpen in new window

ok i will test if they work bu i also need to know how to loop to all records with seq = 1 and read each column in the xml?

I need to update the row where SEQ = 1 with new information in the solution you sent :  CBOIN_new_hour  is not used
so how you are updating cboin value with teh new value ?

Kindly advise

var CBOIN_new_hour = "11:09";
var SEQ_value = "1";
$("NewDataSet DsResQuery SEQ", m_XML_segments_Grid).filter(function() { return $(this).text()==SEQ_value; }).parent().find("CBOIN").text($("NewDataSet DsResQuery SEQ", m_XML_segments_Grid).filter(function() { return $(this).text()==SEQ_value; }));

Select allOpen in new window

also what if i need to  updtae cboin with new vaue for records in xml that has seq = 0 and p_segid = 1 how to do that?

any help?

here a test page : https://jsfiddle.net/mqu24x87/

var SEQ_value = "2";
$("NewDataSet DsResQuery SEQ", m_XML_segments_Grid).filter(function() { return $(this).text()==SEQ_value; }).each(function(i,v) {
         var DsResQuery = $(this).parent();
         var CBOIN = $("CBOIN", DsResQuery).text();
         var SEGMENTNBRE = $("SEGMENTNBRE", DsResQuery).text();
         alert("CBOIN text is " + CBOIN + "\nSEGMENTNBRE text is " + SEGMENTNBRE);
});

Select allOpen in new window

also what if i need to  updtae cboin with new vaue for records in xml that has seq = 0 and p_segid = 1 how to do that?
on the other hand remove is not woking for me(i want to  loop for all records in xml that has seq = 2 and delete the related node  how to do that ?

var SEQ_value = "2";
$("NewDataSet DsResQuery SEQ", m_XML_segments_Grid).filter(function() { return $(this).text()==SEQ_value; }).each(function(i,v) {
         var DsResQuery = $(this).parent();
         var CBOIN = $("CBOIN", DsResQuery).text("mefkemdlkmldkmdgkdk");  // need to  updtae cboin with new vaue
         $(this).parent().remove(); // remove DsResQuery where SEQ = 2
         DsResQuery.remove(); // remove DsResQuery where SEQ = 2
});

Select allOpen in new window

ok delete is working and update is working for a specific where condition (seq = 2)
what if i want to updatecboin with new value for records in xml that has seq = 2 and p_segid = 1 how to do that?

if you initial question is answered, please open a new thread

No, my main question was  conserning insert /update and delete
delete and insert are well answered i  till have the update problem
(what if i want to updatecboin with new value for records in xml that has seq = 2 and p_segid = 1 how to do that?)
