Bug: Double Apostrophe in <value> URI Formatting Issue

[Alfystar]

Description:
I encountered a problem with the @prettier/plugin-xml plugin. When an XML file contains the text:

<value>&apos;&apos;</value>

Prettier rewrites it as:

<value>
    &apos; &apos;
</value>

This formatting adds an unwanted space between the apostrophes, which disrupts the appearance of our system.

Steps to Reproduce:

1. Create an XML file with the following content:

   <root>
       <value>&apos;&apos;</value>
   </root>

2. Run Prettier with the @prettier/plugin-xml plugin.
3. Observe the formatted output.

Expected Behavior:
The content of the <value> tag should remain <value>&apos;&apos;</value> without adding spaces.

Actual Behavior:
The content of the <value> tag is rewritten as:

<value>
    &apos; &apos;
</value>

Additional Information:
In other cases, when there is only one apostrophe, Prettier formats correctly by keeping the line together:

<values>
    <field>ITA_IFM_ActivityDescription__c</field>
    <value xsi:type="xsd:string">MEDIA COMPLESSITA&apos;</value>
</values>

This leads us to believe it is a minor bug. Could you please provide feedback?

Thanks in advice, i'm here if you need anything else 😊

[Alfystar]

Have you news about this bug?

[Alfystar]

Excuse me, can I at least know if you consider this a bug?

[kddnewton]

I'm not sure if this is a bug or not. You're setting it to "preserve", which means in some cases we keep the whitespace and in some cases we do not. I will investigate further.

[Alfystar]

The problem remains, we had to exclude that resource to avoid problems in fact

If you can fix it that would be great!
