[kuro-mujou]

hello developers,
how to get the book title and author for CBZ file? or at least get the ComicInfo.xml file inside CBZ file.

this is my first time i work with readium. I just need parser to extract book info and content. Here my code when trying to Log everything out to see what inside the Publication object:

 val httpClient = DefaultHttpClient() val assetRetriever = AssetRetriever( contentResolver = context.contentResolver, httpClient = httpClient ) val publicationOpener = PublicationOpener( publicationParser = DefaultPublicationParser( context = context, httpClient = httpClient, assetRetriever = assetRetriever, pdfFactory = null, additionalParsers = listOf( EpubParser(), AudioParser( assetSniffer = assetRetriever ), ImageParser( assetRetriever = assetRetriever ), ReadiumWebPubParser( context = context, httpClient = httpClient, pdfFactory = null, ) ) ) ) val uriString = inputData.getString(ImportWorker.Companion.INPUT_URI_KEY)?: return@withContext Result.failure() val uri = uriString.toUri() val url = uri.toAbsoluteUrl() val asset = assetRetriever.retrieve(url!!).getOrNull() val publication = publicationOpener.open(asset!!, allowUserInteraction = true).getOrNull() Log.d("Publication context: ", publication?.context?.joinToString("\n").toString()) publication?.metadata?.toJSON()?.toMap()?.onEachIndexed { index, it -> Log.d("Publication metadata$index: ", it.toString()) } publication?.container?.forEachIndexed{ index,it-> Log.d("Publication container item $index: ", it.toString()) } publication?.readingOrder?.forEach{ it.toJSON().toMap().onEachIndexed { index, it -> Log.d("Publication reading order $index: ", it.toString()) } } publication?.tableOfContents?.forEach { it.toJSON().toMap().onEachIndexed { index, it -> Log.d("Publication table of contents $index: ", it.toString()) } } publication?.subcollections?.toMap()?.onEachIndexed { index, it -> Log.d("Publication sub collections $index: ", it.toString()) } 

i found that it can parse the cbz file.
but i dont see anything from publication.metadata (this work with epub file and it super detail)
i saw that inside the publication.container, it also recognized the ComicInfo.xml

(LOG) 10:46:18.960 Publication container item 0: ComicInfo.xml 

so i tried to get the content from that ComicInfo.xml file but i cant see any log.
here my code:

suspend fun readComicInfoXml(publication: Publication?){ val comicInfoHref = "ComicInfo.xml" publication?.container?.get(comicInfoHref.toUri().toAbsoluteUrl()!!)?.buffered()?.use { it.read().onSuccess {byteArray-> val text = byteArray.decodeToString() Log.d("Publication", text) } } } 

so does anyone know how to get the book info from cbz?

okay i change my code to read that xml file and it work!

suspend fun readComicInfoXml(publication: Publication?) { val comicInfoHref = "ComicInfo.xml" val url = Url(comicInfoHref) val resource = publication?.container?.get(url!!) if (resource == null) { Log.w("Publication", "ComicInfo.xml not found in container") return } val result = resource.read() result.onSuccess { byteArray -> val parserFactory = XmlPullParserFactory.newInstance() parserFactory.isNamespaceAware = true val parser = parserFactory.newPullParser() parser.setInput(ByteArrayInputStream(byteArray), null) var eventType = parser.eventType var series: String? = null var writer: String? = null while (eventType != XmlPullParser.END_DOCUMENT) { when (eventType) { XmlPullParser.START_TAG -> { when (parser.name) { "Series","series" -> { series = parser.nextText()?.trim() } "Writer","writer" -> { writer = parser.nextText()?.trim() } } } } eventType = parser.next() } Log.d("Publication", "Series: $series") Log.d("Publication", "Writer: $writer") }.onFailure { error -> Log.e("Publication", "Failed to read ComicInfo.xml: ${error.message}") } }
