Alter string using regex in Java

Question

I have a XML file loaded into a String like this

<children name="{content.type}">
    <values>{video}</values>
</children>
<children name="{content.size}">
    <values>250</values>
</children>
<children name="uploaded by">
    <values>user1</values>
</children>

I want to remove the {} in the name tags so the output looks like this

<children name="content.type">
    <values>{video}</values>
</children>
<children name="content.size">
    <values>250</values>
</children>
<children name="uploaded by">
    <values>user1</values>
</children>

Currently I have this code -

Pattern p = Pattern.compile("([^,]*)\"\\{([^,]*)\\}\"([^,]*)");
Matcher m = p.matcher(content);
if (m.find()){
    System.out.println(m.group(1));
}

But the string gets cutoff midway. Is something wrong with my regex?

Don't you need to concatenate the second and third group? You are printing only the first captured group right now I think. — Jerry

How about

content.replaceAll("\\bname=\"\\{([^}]+)\\}\"", "name=\"$1\"")

Will this work ?

s.replaceAll( "name=\"\\{", "name=\"" ).replaceAll( "\\}\">", "\">" )

This will work only if OP wont have other attributes in his input like <children name="{content.type}" someOtherAttrib="{some.value}">
