如何在 JavaScript 中使用正则表达式查找字符串？

Question

This is the string from which I need to do searching -

<bpmn:process id="Process_1" isExecutable="false">
<bpmn:task id="Task_15xgmrn" name="Select1Select5" extratask:entity="Select1" extratask:action="Select5"/>
<bpmn:extensionElements> <camunda_1:executionListener class="org.camunda.bpm.getstarted.loanapproval.MyTaskList" event="start"/> </bpmn:extensionElements>
<bpmn:task id="Task_0ditp3t" name="Select2Select6" extratask:entity="Select2" extratask:action="Select6" camunda_1:exclusive="false" camunda_1:asyncAfter="true" camunda_1:async="true" />
<bpmn:extensionElements> <camunda_1:executionListener class="org.camunda.bpm.getstarted.loanapproval.MyTaskList" event="start"/> </bpmn:extensionElements>
<bpmn:task id="Task_0ffkkda" name="Select2Select4" extratask:entity="Select2" extratask:action="Select4"/>
<bpmn:task id="Task_0p68hrl" name="Select3Select6" extratask:entity="Select3" extratask:action="Select6"/>
</bpmn:process>

And search result should be like this -

<bpmn:task id="anything" name="anything" extratask:entity="anything" extratask:action="anything" />

all the occurrence of the result.

I have made some changes in the search string, some attributes have been added into the second "bpmn:task" tag. And I don't want that tag to be get selected in the search result.

Am I correct that what you actually want to do is collect all the bpmn:task XML tags, because this can actually be as small as:

str.match(/<bpmn:task.+?>/g)

Or as the person in the comment pointed out

str.match(/<bpmn:task id=".*"\s*name=".*"\s*extratask:entity=".*"\s*extratask:action=".*"\s*\/>/g)

However if you want to anything more with the XML I do highly recommend using a parser.
