Looking for a way to replace double quotes within specific characters in a String. Here's an example string:
"XML": "<MyTag>"Value1"</MyTag><MyTag2>Value2</MyTag2>"
The desired output is:
"XML": "<MyTag>\"Value1\"</MyTag><MyTag2>Value2</MyTag2>"
Attempts with regexr to match the quotes have been unsuccessful like:
/<MyTag>(")<\/MyTag>/
/(<MyTag>)"(<\/MyTag>)/
Can quotes between tags be escaped?
When dealing with a very specific scenario, like the one you described, using a simple replace() function can be a more efficient and resource-friendly solution:
var str = '"XML": "<MyTag>"Value1"</MyTag><MyTag2>Value2</MyTag2>"';
// replace
str = str.replace('<MyTag>"','<MyTag>\\"');
str = str.replace('"</MyTag>', '\\"<MyTag>');
// test
alert(str);
You can also find this code on JSFiddle:
https://jsfiddle.net/xbe1x0mz/
let myString = '"<MyTag>"content1"</MyTag><MyTag>content2</MyTag>"';
let firstReplace = myString.replace(/<MyTag>"/g, "<MyTag>\\\"");
let secondReplace = myString.replace(/"</MyTag>/g, "\\\"<MyTag>");
// secondReplace = "<MyTag>\"content1\"</MyTag><MyTag>content2</MyTag>";
Avoid using regular expressions to manipulate XML data. It's much better to follow these simple steps:
// Convert XML string to DOM:
var rootNode = new DOMParser().parseFromString(XML_DATA, 'text/xml');
// Manipulate desired elements:
var tags = rootNode.querySelectorAll('DesiredTag');
for (var j = 0; j < tags.length; j++) {
var tag = tags[j];
tag.textContent = tag.textContent.replace(...);
}
// Convert modified DOM back to XML string:
var updatedXML = new XMLSerializer().serializeToString(rootNode);
