Set indentation for attributes in new lines

[MuntashirAkon]

There is an option to set indentation for child tags in XMLDocument but no option to set indentation for new line attributes and they are at present calculated at XMLElement#appendAttributesIndentText(Writer). It might be better to provide an option to set indentations instead of calculating them. For example, instead of providing an argument boolean newLineAttributes, you can provide int attributeIndentation whose negative value (e.g. -1) would imply no new line and any positive number would imply the amount of indentation.

Thanks.

I agree , there a lot of other issues to fix on com.reandroid.xml.* classes.

Any updates?

Sorry I don't know how I forgot this issue.
Keeping newLineAttributes, I have added setAttributesIndentScale(float indentScale) for elements, you can set negative value to pull back.

It only scales the calculated indentation, it does not set the indentation.

I feel like i missed your point. As on the last commit you can set indentation to any position you like, I kept newLineAttributes param to turn off/on indentation. The indentation for attributes must be calculated bc it is anchored with parent element.
Can you show me your goal with screenshoot/document ? Or make PR

I have ended up writing a concrete implementation of XmlPullParser to handle this. As I said in #18, I don't think XML conversion should be part of the library as it can be handled quite easily using XmlSerializer and Transformer functions.
