Javascript正则表达式匹配xml标签

Question

I am going to match something like <textEntryInteraction responseIdentifier="RESPONSE" expectedLength="15"/> , and I want it to be occur once only. When I use /<textEntryInteraction [^>]+\\/>/g to search and match the tags, I don't know why pattern.test(xml) return false.

However, if i use /<textEntryInteraction [^>]+\\/>/ , it return true.

Can anyone helps me?

If I were you I would seriously consider looking at jQuery instead of regex for this type of work. You can do something like this.

var $xml = $($.parseXML(yourXMLcontent));
var $textEntries = $xml.find('textEntryInteraction');

You can then filter your textEntries by attribute values .

filter function
