Read and convert XML file block to description

Hi,
I have a custom module and function which read XML and create the description from:

<features>
<feature title="Color" id="6100"><![CDATA[White]]></feature

And it create the description like:
Color: White

But now I have a different XML
<category_properties>
<category_property name="Sim slot">
<values>
<value>
<name>Single Sim</name>
</value>
</values>
</category_property>
And I need to read the data from <values> block to:

Sim Slot: Single Sim

Some blocks are with few value data:

<category_property name="Other">
<values>
<value>
<name>4G/LTE, Bluetooth 5.0, A-GPS, GLONASS, GALILEO, QZSS</name>
</value>
<value>
<name>Wi-Fi 802.11 a/b/g/n/ac/ax, dual-band, hotspot</name>
</value>
<value>
<name>Face ID, Stereo speakers Dolby Atmos, Qi безжично зареждане</name>
</value>
<value>
<name>Двойна основна камера 12 MP 26mm (wide) + 12 MP 13mm (ultrawide)</name>
</value>
